so i have this code(not in details)
<p:tabView id="tabviewId">
<p:tab>
<h:form id="mainHeadOfAccountsId_form">
// some input fields with validation
// using viewscoped
<p:commandButton value="Add" process="mainHeadOfAccountsId_form" update="mainHeadOfAccountsId_form :#{p:component('allMainHeadOfAccountsId_table')} :#{p:component('successfullySavedUpdatedId_growl')}" action="#{budgetHeadOfAccountsAction.addMainHeadOfAccountsOnAjax}" />
/// also using <p:datatable id= "allMainHeadOfAccountsId_table" >
</h:form
</p:tab>
<p:tab>
<h:form>
</h:form
</p:tab>
</p:tabView>
<p:growl id="successfullySavedUpdatedId_growl" for="successfullySavedUpdatedFor_growl" value="error" showDetail="false" />
my Question is that when i submit form mainHeadOfAccountsId_form successfully i need to update(reset) all fields which are in mainHeadOfAccountsId_form
but remember that i am also using <h:selectOneMenu> so i want to reset(option[0] selected) not empty, how can i do that ? currently its updating allMainHeadOfAccountsId_table and successfullySavedUpdatedId_growl except mainHeadOfAccountsId_form
i have tired tabviewId:mainHeadOfAccountsId_form but getting exception component not found,
as i am thinking this is just because of #viewScoped and i should reset value of those inputs in my action class (.java), m i right ?
see what primefaces offer for reset input or after submitting the form by the action in the bean reset the values by new or null and recreate the list held by
<h:selectOneMenu>

i am trying to make composite component(multiply use on each view) which allows me to show some inputs by checkbox value. One input is depended on checkbox value. I dont want to bind it to bean cause this value is not saved to database or so. I though that i ll save it in view scope holder.
I ve added in face config holder for bindings
<managed-bean>
<description>Holder of all component bindings.</description>
<managed-bean-name>components</managed-bean-name>
<managed-bean-class>java.util.HashMap</managed-bean-class>
<managed-bean-scope>view</managed-bean-scope>
</managed-bean>
composite component:
<p:selectBooleanCheckbox binding="#{components[cc.attrs.bindingId]}">
<p:ajax update="panel"/>
</p:selectBooleanCheckbox>
<h:panelGroup id="panel">
<p:inputText rendered="#{components[cc.attrs.bindingId].value}" value="#{cc.attrs.beanPropertyOnTrue}">
<p:inputText rendered="#{not components[cc.attrs.bindingId].value}" value="#{cc.attrs.beanPropertyOnFalse}">
</h:panelGroup>
It works fine, I can use this component multiply on one view, but the problem is when i am using commandButton to send form to server, checkboxes are changing to unchecked....
<p:commandButton value="show decision dialog"
actionListener="#{testBean.action}"
update="#form"
oncomplete="if (args && !args.validationFailed){ dialog.show() }"/>
I'm new to JSF, my question may be silly for you.. It is very much valuable for me..
<h:form id="form1">
<p:messages autoUpdate="true" showDetails="true" />
<p:dataTable id='form1ID'>....</dataTable>
<p:inputText value="#{bean.name}" required="true"
requiredMessage="Please Enter Name!" label="Name ">
</p:inputText>
</h:form>
<h:form id="form2">
<p:messages autoUpdate="true" showDetails="true" />
<p:dataTable id='form2ID'>....</dataTable>
<p:inputText value="#{bean.name}" required="true"
requiredMessage="Please Enter Name!" label="Name ">
</p:inputText>
<p:commandButton value="Submit" update=":form1:form1ID"
actionListener="#{mgmtBean.doCreateType}" />
</h:form>
I have two forms. when I click on form2 command button with empty fields, it will show error messages perfectly since i have added <p:messages autoUpdate="true" showDetail="true"/>.
The bad thing or surprising thing here for me is, it is showing error messages on top of form1 also may be because of <p:messages autoUpdate="true" showDetail="true"/> added in form1 and i'm trying to update form1 on command button click in form2.
I don't want to show error messages on form1 when form2 is throwing validation error messages. How can i fix this ? I googled it out.. but couldn't find the solution.
Evironment i'm using is jsf-api-2.1.5 and primefaces 4.0 version and view technology is facelets(XHTML)
Hope it is clear..
Any idea is highly appreciated.
Try to disable rendering of messages on the form1:
<p:messages autoUpdate="true" showDetails="true" rendered="#{bean.renderedmessage}"/>
And in the bean, add the renderedmessage variable:
public Boolean getRenderedmessage() {
return renderedmessage;
}
/**
* #param renderedmessage the renderedmessage to set
*/
public void setRenderedmessage(Boolean renderedmessage) {
this.renderedmessage = renderedmessage;
}
And, for the doCreateType() method, add:
public void doCreateType(){
..............
setRenderedmessage(false);
.............
}
After the form1 is updated, you can choose some event or method, where you can setRenderedmessage(true);
What you're currently experiencing should indicate to you that you usually don't need two <p:messages/>s in the same JSF view; one is enough.
Regardless of the fact that you have two <h:form/>s on your page, there's still only one FacesContext associated with that view (The FacesContext object is a JSF construct that encapsulates all the information/data/components etc that's associated with a given JSF page request).
By default the <p:messages/> will display every FacesMessage that is queued within it's associated instance of FacesContext, regardless of the source of the message (well, almost: if you set globalOnly="true" on the <p:messages/>, you can change that behaviour).
That being said, you basically have two options:
Get rid of the extra <p:messages/> and rely on (and appropriately position) only one to display all errors/warnings for that view
Specify the for attribute, set to the desired component. Doing so, you'll guarantee that only one input component can trigger the display of its associated message component. For example
<h:form id="form1">
<p:messages for="inputName" autoUpdate="true" showDetails="true" />
<p:dataTable id='form1ID'>....</dataTable>
<p:inputText id="inputName" value="#{bean.name}" required="true"
requiredMessage="Please Enter Name!" label="Name ">
</p:inputText>
</h:form>
Note that I've set an id attribute on the <p:inputText/> component; this is necessary so you can use it in the for attribute for the messages component.
Further reading:
What is FacesContext used for?
I have fixed the issue by using the following code
<p:messages autoUpdate="true" showDetails="true" visibility="info"/>
so it is just displaying info messages and other pop up error messages will not be showun.
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 have two forms in my page, in the first formulary are input fields with validation, and in the other a dataTable. The first formulary has a message area to show validation errors, and the second formulary has a message area to show problems with the retrieval of the data (this message area is updated from myController.search).:
<h:form id="form1">
<p:message id="messageForm1" for=":form1" />
<p:inputText id="text1" value="#{myBean.data}" required="true" />
....
<p:commandButton value="Search" actionListener"#{myController.search}"
update=":form2:dataTable :form2:messageForm2 :form1:messageForm1" process="text1, ..." />
</h:form>
<h:form id="form2">
<p:message id="messageForm2" for="messageForm2" />
<p:dataTable>
...
</p:dataTable>
</h:form>
The problem is that the messages in the form2 are working, but the validation messages in form1 are never shown
The description of the for attribute of the p:message tag says:
Id of the component whose messages to display.
So you can't specify the ID of the form. You have to specify the ID of a single form component. e.g. <p:message id="messageForm1" for="text1" />. But then you have to create one message element for every form component.
An alternative would be to use the p:messages tag. For examples see here: http://www.primefaces.org/showcase-labs/ui/messages.jsf
Here I am again with a JSF problem, this time it is more about richfaces (4.2.1 final, JSF 2). I have an eytended DataTable and want to add new items. There ist the List of Journey-objects, every attribute have getter and setter. The table is created well (there are already some items in the list). And now I click the "add new item" button:
<a4j:commandButton ajax="true" value="Neue Fahrt hinzufügen"
actionListener="'{editorBean.prepareCreateJourney}" render="createJourneyPopupForm"
oncomplete="#{rich:component('createJourneyPopup')}.show()" />
The editorBean is SessionScoped, the method is properply called and create a new object of Journey called currentJourney. A popup comes up and should allow me to insert some input:
<rich:popupPanel id="createJourneyPopup" modal="true">
<h:panelGrid id="createJourneyPopupForm" columns="3">
<h:outputLabel for="currentId" value="ID" />
<h:inputText id="currentId"
value="#{editorBean.currentJourney.journeyNumber}" />
<rich:message for="currentId" />
[...and more...]
</h:panelGrid>
<a4j:commandButton value="Save"
execute="currentId currentTrainType operator">
<f:ajax event="click" listener="#{editorBean.doCreateJourney}"
render=":vmsEditorForm:resultTable" />
<rich:componentControl target="createJourneyPopup" operation="hide" />
</a4j:commandButton>
<a4j:commandButton value="Abbrechen"
onclick="#{rich:component('createJourneyPopup')}.hide();" />
</rich:popupPanel>
When i clicked the button, the method doCreateJourney is called, but the currentJourney is empty. It is the default Journey object after creating it. No setter was called, do a hint on the inputfields.
I checked the names twice, there are getters and setters for alle needed objects. I tried to change the scope, but no effect. Objects are the same, in the prepare method i created Journey(id=151) and in the save method it is still Journey(id=151).
What is going on here? I can't be this difficult to make some dialogs to create and edit data objects. Thank you for listening and for your help!
You need to wrap both your inputs and your commandButtons in a form in order to correctly submit the data.
<rich:popupPanel id="createJourneyPopup" modal="true">
<h:form>
... the content of your popupPanel
</h:form>
</rich:popupPanel>
