I have an extendedDataTable with a selectionchange event and selectionMode="single". Furthermore I work with the attribute "onrowdblclick" wich invokes a JavaScript function.
<rich:extendedDataTable id="myTable" ... selectionMode="single" var="item" selection="#{myController.selection}" onrowdblclick="showPageByDoubleClick('#{item.id}');">
<a4j:ajax event="selectionchange" listener="..."/>
My question is, how can I prevent the extendedDataTable from invoking the selectionchange event if the user has double clicked a row?
On double click I forward to a new page and the selectionchange event takes too much time, thus the page forwarding is delayed. We have very strict performance requirements.
I'am using RichFaces 4.5.9
Best regards
Ok, everything I had to do is to work with a queue and to group both requests in one queue. The queue treats both requests as the same request and thus the ignoreDupResponses attribute is working.
Example:
<h:form id="myform">
<a4j:queue name="overviewSelectionQueue" ignoreDupResponses="true" requestDelay="200"/>
<a4j:jsFunction name="editWithDoubleClick" action="#{myController.editWithDoubleClick}">
<a4j:param name="selectedId" assignTo="#{myController.selectedId}" />
<a4j:attachQueue name="overviewSelectionQueue" requestGroupingId="overviewSelection"/>
</a4j:jsFunction>
<rich:extendedDataTable id="myTable" value="#{myController.myList}" var="item" selectionMode="single"
selection="#{myController.selection}" onrowdblclick="editWithDoubleClick('#{item.id}');">
<a4j:ajax event="selectionchange" listener="#{myController.overviewTableSelectionChanged}"
execute="#this" limitRender="true">
<a4j:attachQueue name="overviewSelectionQueue" requestGroupingId="overviewSelection"/>
</a4j:ajax>

Hello I am new to JSF ice faces, and i am stuck on one point.
I have checkboxButton inside a tree. The checkboxes has associated action listeners.
Issue is that the action listener is only invoked for the top level check box (at the root node), not for the checkbox which are at the child or leaf of the tree. Am i missing something?
<ace:tree var="treeNode" value="#{clientUserAdmin.segmentationTree}" expansion="true" selection="false" reordering="false"
rendered="#{!empty clientUserAdmin.clientAccessSelectList and !clientUserAdmin.currentProfile.allSegmentations and user.currentProject.isSegmentationManual}" >
<ace:node>
<h:panelGroup style="display: inline">
<ace:checkboxButton partialSubmit="true"
value="#{treeNode.userObject.treeNodeSelected}"
valueChangeListener="#{clientUserAdmin.onSegmentationAccessChange}"
styleClass="#{treeNode.userObject.classStyle}"
disabled="#{treeNode.userObject.checkBoxDisabled}" >
<ace:ajax execute="#this" render="#all" />
</ace:checkboxButton>
</h:panelGroup>
<h:panelGroup style="display: inline">
<h:outputText value="#{treeNode.userObject.text}"
styleClass="#{treeNode.userObject.classStyle}" />
</h:panelGroup>
</ace:node>
</ace:tree>
I can see that the request is sent to the server and onSuccess is always executed for every check box value change. but value change listener is never invoked for child node check boxes.
thanks in advance
I couldn't find the solution to the original issue.
I changed to my code to use h:selectBooleanCheckbox instead of ace:checkboxButton
Also instead of ace:ajax execute="#this" render="#all", i changed to
f:ajax event="click" execute="#form" render="#form"
Now it is working as expected. If someone can explain what is happening, will be a great help.
thanks.
I started using primafaces and I came up with the following scenario. The user rates and element and if the rating is valid then a span block appears or it hides depending the case. I am based on the example here: (http://www.primefaces.org/showcase/ui/input/rating.xhtml ) with the ajax approach. Note that a rate is valid if the user clicks on any star. So here's what I've done so far:
<h:form>
<p:panelGrid>
<p:row>
<p:column>
<p:rating value="#{searchBean.dateWeight}">
<p:ajax event="rate" listener="#{searchBean.addDatetoWeights}"
update="dates" render="dates" />
<p:ajax event="cancel"
listener="#{searchBean.removeDatefromWeights}"
update="dates" />
</p:rating>
<h:panelGroup id="dates" rendered="#{searchBean.dateRated}">
<h:outputText value="test"></h:outputText>
</h:panelGroup>
</p:column>
</p:row>
</p:panelGrid>
</h:form>
segment of the bean:
boolean dateRated;
int dateWeight;
public void addDatetoWeights(){
dateRated=true;
weights.put("date",dateWeight);
System.out.println(dateRated);
}
public void removeDatefromWeights(){
dateRated=false;
if(weights.containsKey("date"))
weights.remove("date");
}
Let's go back to the basics: HTML and JavaScript. It's important to also know them before diving into JSF. JSF is in the context of this question merely a HTML/JS code generator.
With <p:ajax update="dates"> you're basically telling JavaScript to grab the HTML element by the given ID and then replace its contents with the new contents retrieved from server in ajax response. However, as the <h:panelGroup id="dates"> is in first place never rendered to the HTML output, JavaScript can't find the element by document.getElementById() stuff in order to replace its contents and then just ignores the instruction.
Instead, the <p:ajax update="dates"> must refer a component which is always rendered, so that JavaScript can actually find it. Only its contents can be conditionally rendered.
Here's a rewrite:
<h:panelGroup id="dates">
<h:outputText value="test" rendered="#{searchBean.dateRated}" />
</h:panelGroup>

I've just started learning JSF and PrimeFaces, and as soon as I solve a problem (with your help), another one arises. I have a datatable showing some data about my application's users; in the last column, a commandButton invokes a dialog allowing the corresponding data to be edited. The dialog actually interacts with the backing bean, since the fields are correctly precompiled with the existing data, but the "Submit changes" commandButton doesn't fire the proper editUser() method!
I've searched everywhere for a solution to my problem, but none of the threads on the PrimeFaces forums nor any question here on Stack Overflow helped me: I tried all combinations of action, actionListener, inner <h:form>, outer <h:form>, even the dreaded nested <h:form>, but the underlying method is still not called.
Thank you all, people!
EDIT: I included some more xhtml. Just to be clear: in the datatable I'm implementing both single and multiple selection mechanisms. The single selection is performed by the editButton in the last column and triggers the editDialog that's giving me pain, while multiple selection is enabled by the checkboxes in the first column and is targeted by a commandButton at the bottom of the table that deletes all selected users; of course they store the selections in different fields in the backing bean (selectedUser and selectedUsers[], respectively).
xhtml file
<h:form id="tableForm">
<p:dataTable id="userList" var="user" value="#{userListBean.userList}"
selection="#{userListBean.selectedUsers}" rowKey="#{user.username}">
<!-- this is a checkbox column I use for multiple selection -->
<p:column selectionMode="multiple" style="width:2%"/>
<!-- other datatable columns -->
<!-- this is the button column that triggers the dialog -->
<p:column style="width:4%">
<p:commandButton id="editButton" update=":tableForm:editUserData"
oncomplete="PF('editDialog').show()" title="Edit" icon="ui-icon-pencil">
<f:setPropertyActionListener target="#{userListBean.selectedUser}"
value="#{user}" />
</p:commandButton>
</p:column>
</p:datatable>
<p:dialog id="editDlg" widgetVar="editDialog" header="Edit User"
showEffect="fade" hideEffect="fade" modal="true" dynamic="true">
<h:panelGrid columns="6" id="editUserData">
<p:outputLabel for="editUsername">Username:</p:outputLabel>
<p:inputText disabled="true" id="editUsername" value="#{userListBean.selectedUser.username}" />
<p:message for="editUsername" />
<!-- and other fields like that -->
</h:panelGrid>
<p:commandButton id="submitChanges" action="#{userListBean.editUser()}"
value="Submit changes" oncomplete="PF('editDialog').hide();" />
</p:dialog>
</h:form>
Backing bean
#ManagedBean(name="userListBean")
#ViewScoped
public class UserListBean {
private UserDTO selectedUser;
public UserListBean() {
}
//some methods...
public String editUser() {
System.out.println("------------------ EDIT TRIGGERED! -------------------");
System.out.println(selectedUser.getUsername());
//this stuff never gets printed, so the method is never called!
}
//getters and setters
}
Actually, the only thing didn't come to my mind turned out to be the one that worked.
I sorted out my issue by using THREE forms (as I mentioned in my question, I had already tried out all possible combinations of one and two forms, even nested ones), like this:
<h:form id="tableForm">
<!-- here lies the p:dataTable -->
</h:form>
<p:dialog>
<h:form id="dialogForm">
<!-- here lies the h:panelGrid with the editable fields -->
</h:form>
<h:form id="buttonForm">
<!-- and HERE goes the commandButton, alone -->
</h:form>
</p:dialog>
It looks like everyone solves this problem in ways that don't work for others :) .
I am building an app where one of the requirements is heavy use of hotkeys. So heavy in fact that we want to pull those hotkeys back into a central controller.
The basic idea is each page will have a key associated with it. When jsf hits that key, it will go back to a central enummap to decide what hotkeys are supposed to be associated with that page and what methods are supposed to be added to the keys of that page.
My problem is the dynamic load. I can't use the
For now, I have this
<h:form binding="#{hotkeyController.form}">
<f:event listener="#{hotkeyController.genKeyHandler('HOTKETEST')}" type="preRenderComponent"/>
<p:outputPanel id="displayHotkey">
<h:outputText value="#{hotkeyController.keyText}" rendered="#{not empty hotkeyController.keyText}"/>
</p:outputPanel>
</h:form>
Then for my backing bean i have this
public void genKeyHandler(String pageKey) {
Hotkey hotkey = new Hotkey();
hotkey.setBind("ctl+shift+d");
hotkey.setAsync(true);
// "#{hotkeyController.keyHandler('HOTKETEST', 'F1')}"
hotkey.setActionExpression(createMethodExpression("#{hotkeyController.keyHandler('HOTKEYEXAMPLE', 'CTLSHIFTD')}", null,
String.class, String.class));
hotkey.setUpdate("displayHotkey");
form.getChildren().add(hotkey);
hotkey = new Hotkey();
hotkey.setBind("ctl+shift+a");
hotkey.setAsync(true);
// "#{hotkeyController.keyHandler('HOTKETEST', 'F1')}"
hotkey.setActionExpression(createMethodExpression("#{hotkeyController.keyHandler('HOTKEYEXAMPLE', 'CTLSHIFTA')}", null,
String.class, String.class));
hotkey.setUpdate("displayHotkey");
form.getChildren().add(hotkey);
}
Now this works in the sense that it actually inserts the hotkey into the form. I can see it in inspector. But, my problem is two fold. One, if I refresh the page, I get duplicate ID errors, if I use the preRenderView, I get "Error restoring component" errors. seems like no combination will work.
Is there any way to make this work? All I want is to have the bean method that inserts the hotkeys fire the first time a page is loaded and only fired once in the life of the page/view/whatever. This shouldn't be this hard.
My suggestion is that you use an exclusive form for the hotkeys.
Here is the sample:
<h:form id="mainForm">
<p:remoteCommand name="loadHotKeys" action="#{hotkeyController.genKeyHandler('HOTKETEST')}" update=":hotkeyForm" global="false" process="#this" />
<p:outputPanel id="displayHotkey">
<h:outputText value="#{hotkeyController.keyText}" rendered="#{not empty hotkeyController.keyText}"/>
</p:outputPanel>
</h:form>
<h:form id="hotkeyForm" binding="#{hotkeyController.form}" />
<script type="text/javascript">
jQuery(document).ready(loadForm());
</script>
And the genKeyHandler method should clear the hotkeyForm (form.getChildren().clear()) before adding the hotkeys.
I'm using PrimeFaces dataTable and rowEditor in pretty default way:
<p:dataTable id="payments-table" var="apayment" value="#{payment.payments}" editable="true">
<p:ajax event="rowEdit" listener="#{payment.update}"/>
...
</p:dataTable>
I'd like a confirmation dialog to show itself on clicking to the 'check' button of rowEditor.
I know it's possible using JS confirm function (thanks to Show a confirm message before <p:rowEditor> updates the model on click of "OK" button):
<p:ajax event="rowEdit" listener="#{payment.update}" onstart="return confirm('Save changes?')"/>
But I would like the dialog to conform to the UI theme, confirmDialog component being the best candidate. Alas, I don't know how to use it here. I tried the following and it won't work (simply no confirmation occurres):
<p:ajax event="rowEdit" listener="#{payment.update}">
<p:confirm header="Remove payment" message="Remove payment?" icon="ui-icon-trash"/>
</p:ajax>
....
<p:confirmDialog global="true">
<h:form id="form-payment-confirm">
<p:commandButton value="Yes" type="button" styleClass="ui-confirmdialog-yes" icon="ui-icon-check"/>
<p:commandButton value="No" type="button" styleClass="ui-confirmdialog-no" icon="ui-icon-close"/>
</h:form>
</p:confirmDialog>
Any ideas?
I think you can use in this case simple widgetVar and call show() or hide() functions. Here is your modified code:
<p:ajax event="rowEdit" listener="#{tableBean.onRowEdit}" oncomplete="myDialog.show()"/>
I use PF 3.5 and can't find global parameter in p:confirmDialog. May be it is new feature. So I simple deleted it of my code. Here is modified confirmDialog:
<p:confirmDialog widgetVar="myDialog" closeOnEscape="true" appendToBody="true" closable="true">
<h:form id="form-payment-confirm">
<p:commandButton value="Yes" type="button" update="#form" styleClass="ui-confirmdialog-yes" icon="ui-icon-check"/>
<p:commandButton value="No" type="button" onclick="myDialog.hide()" styleClass="ui-confirmdialog-no" icon="ui-icon-close"/>
</h:form>
</p:confirmDialog>
Please try and adjust this confirm dialog code! May be unnecessary code for update form or hide()...
EDIT:
If you want to dynamically adjust text message of confirmDialog, you can adjust from server-side. Perhaps it is not best solution. I think the second way is it adjust from client-side by JQuery.
Server-side:
The ajax event is same. It call onRowEdit listener which adjust simple String attribute. For example the bean containt:
String myDialogMessage = "Default message";
//getter and setter
public void onRowEdit(RowEditEvent event) {
myDialogMessage="Are you sure?";
}
and the dialog containt message property:
<p:confirmDialog widgetVar="myDialog" closeOnEscape="true" appendToBody="true" closable="true" message="{tableBean.myDialogMessage}">
Client-side:
You can use repleaceWith function of JQuery:
<script>
jQuery("myDialog.p").replaceWith(....
</script>
Of course need to develop more business logic to client-side, more functions. Maybe the server-side solution is faster.
Please try it!
Based on your comment, I edited:
I find this in 4.0 user' guide:
When pencil icon is clicked, row is displayed in editable mode meaning
input facets are displayed and output facets are hidden. Clicking
tick icon only saves that particular row and cancel icon reverts the
changes, both options are implemented with ajax interaction. Another
option for incell editing is cell editing, in this mode a cell
switches to edit mode when it is clicked, losing focus triggers an
ajax event to save the change value.
So ajax event works when row is change. Here is dataTable events which can you catch:
I hope this answer help to you find solution!
