ignoreValidationFailed doesn´t work inside p:dataTable - jsf-2

I am using actionListener ajax call inside datatable and trying to do the following :
skip validation
update the model with the inserted values
I knew that omnifaces utility liberary by BalusC can do this using o:ignoreValidationFailed
But it failed with me to work inside primefaces datatable.
Also I found that it failed to work inside ui:repeat in another post here
I dont know if its a bug or not.
here is my code example
<o:form id ="trans_desc_form">
<p:outputPanel id="stkdetailsid">
<p:dataTable id="transactiondetailsid" value="#{stockTransactionsBean.stkTransHeader.stkTransDetailsList}"
var="stkTransDet" rowIndexVar="rowIndex">
<p:column>
<f:facet name="header">
<h:outputText value="Item Code" />
</f:facet>
<p:autoComplete id="dd" required="true"
value="#{stkTransDet.item}" var="i" itemLabel="#{i.itemno} #{i.itemnamee}"
itemValue="#{i}" converter="itemsConverter"
completeMethod="#{stockTransactionsBean.completeItems}"/>
</p:column>
<p:column>
<p:commandButton value="-" update="#form" process="#form"
actionListener="#{stockTransactionsBean.removeRow(rowIndex)}">
<o:ignoreValidationFailed />
</p:commandButton>
</p:column>
</p:dataTable>
</p:outputPanel>
</o:form>
As a workaround, I added
1- add a condition to the required field to know if the ajax come from submit button or not
to the autoComplete component where the trans_desc_form is thte entire form id and savetransid is the submit button save id
required="#{!empty param['trans_desc_form:savetransid']}"/>
2- I removed #NotNull from my JPA entity which force the validation
#JoinColumn(name = "ITEMNO", referencedColumnName = "ITEMNO")
#ManyToOne(optional = false, fetch = FetchType.LAZY)
//#NotNull
private Item item;

To skip validation you can use the immediate="true" attribute on your p:commandButton

Calling listener in p:selectBooleanCheckbox without refreshing the whole dataTable in Primefaces

I have a Primeface selectBooleanCheckbox in a column of a DataTable. Inside there is a <p:ajax that on check calls the method in the listener (mybean.checkCell(cell.field2)) and saves the status of the checkbox.
My problem is that the entire p:dataTable is refreshed when I check.
How do I call mybean.checkCell(cell.field2) without refreshing the whole dataTable?
Here is my code:
<p:dataTable var="cell" value="#{mybean.mycells}" widgetVar="cell" emptyMessage="No cells" filteredValue="#{mybean.filteredCells}">
<p:column filterBy="#{cell.field1}" headerText="Field1" filterMatchMode="contains">
<h:outputText value="#{cell.field1}" />
</p:column>
<p:column headerText="Checkbox">
<p:selectBooleanCheckbox value="#{cell.check}" partialSubmit="true">
<p:ajax process="#this" partialSubmit="true" update=":form:messages" listener="#{mybean.checkCell(cell.field2)}" onstart="PF('statusDialog').show();" oncomplete="PF('statusDialog').hide();" />
</p:selectBooleanCheckbox>
</p:column>
</p:dataTable>
You are updating the component specified in update=":form:messages" everytime click the checkbox. I guess "messages" ID belongs to a container where the datatable is in. If it is not right, i don't understend why the databled gets updated. If it is right, just delete the update attribute or update something that does not contain the datatable inside.

How to dynamically get value of component p:inputText inside a datatable?

I have a primefaces Datatable:
<p:dataTable id="tabela" var="item"
value="#{myBean.lista}"
rowIndexVar="rowindex">
<p:column>
<p:inputText
required="true" id="inputAliquota" value="#{item.taxa}"
>
</p:inputText>
</p:column>
</p:dataTable>
In my backing bean I have a lista:
private List<Aliquota> lista;
And a Button to remove columns from my datatable:
<p:commandLink
immediate="true" id="botaoExcluir"
action="#{myBean.excluirAliquota}"
>
<f:setPropertyActionListener value="#{item}"
target="#{myBean.aliquota}" />
</p:commandLink>
When I start the bean I populate "lista" with 5 empty Aliquota objects.
In excluirAliquota method I get the object that has to be removed, compare with the values of the List and delete it. But I'm having problems. When the user change the value of inputText the change don't reflect the Aliquota object on list.
My question is how to set this value without submit it?
You cannot reflect the value on the backing bean without submitting it. However, you can submit it using Ajax by adding a listener to the input text. The listener method doesn't have to do anything, it can be empty, but it needs to be there for an Ajax submit. It can be something like that:
<p:dataTable id="tabela" var="item"
value="#{myBean.lista}"
rowIndexVar="rowindex">
<p:column>
<p:inputText
required="true" id="inputAliquota" value="#{item.taxa}"
>
<p:ajax listener="#{myBean.dummyListener()}"/>
</p:inputText>
</p:column>
</p:dataTable>
This will instantly reflect all changes in the inputText to the taxa field of the corresponding item. If that's what you want, you can use this method.

Prevent state saving for specific element

I have the following scenario:
I have a dataTable in which I have a column with the following code
<f:facet name="header">
<h:selectBooleanCheckbox styleClass="checkall"
id="my-id-chk" />
<h:outputLabel for="my-id-chk" />
</f:facet>
<h:selectBooleanCheckbox rendered="#{row.selectable}" value="#{row.selected}"
styleClass="checkall_remover" id="row-chk" />
<h:outputLabel for="row-chk" />
When I want to select all rows and delete them:
1) I click on the h:selectBooleanCheckbox in the <f:facet name="header"> and with js I select all rows checkboxes
2) Click on delete button that execute that dataTable and deletes all rows on server , that delete button also renders the dataTable so the deleted rows will be removed from it
Now the thing is that the h:selectBooleanCheckbox in the <f:facet name="header"> keeps its state (checked state)
How can I make that h:selectBooleanCheckbox in the <f:facet name="header"> to be unchecked ?
The solution that I use right now is to render the dataTable from a "proxy" button that is located in other h:form <-- Using that technique causes the h:selectBooleanCheckbox in the <f:facet name="header"> not to remember its state.
But I prefer a cleaner solution without using additional h:form
(I use MyFaces 2.2.3 with Tomcat 7)
Just use plain HTML. JSF state is indeed saved on server side, but HTML state not.
<f:facet name="header">
<input type="checkbox" class="checkall"
id="my-id-chk" />
<label for="my-id-chk" />
</f:facet>
An alternative would be to create a custom component whereby getters/setters don't delegate to UIComponent#getStateHelper() but instead to local properties.

p:commandLink in p:dataTable does not invoke action on first click, but only on second click

I'm using primefaces commandLink in p:datatable and when user clicks on link. It's supposed to navigate to another page including specific info of object that is chosen from table. I don't use any ajax tags. Problem is when first time clicks on link it doesn't invoke action actually nothing happens and on second click it works. Here is my code :
JSF with Datatable
<h:form>
<h:outputText value="Nothing is found" rendered="#{searchView.citizenSearchList.rowCount==0}"/>
<p:dataTable var="cust" value="#{searchView.citizenSearchList}" dynamic ="true" paginator="true" rows="5" paginatorAlwaysVisible="false" style="width: 700">
<p:column>
<f:facet name ="header">
<h:outputText value="name "/>
</f:facet>
<h:outputText value="#{cust.name}"/>
</p:column>
<p:column>
<f:facet name ="header">
<h:outputText value="lastname "/>
</f:facet>
<h:outputText value="#{cust.citizenList.get(0).lastname}"/>
</p:column>
<p:column>
<f:facet name ="header">
<h:outputText value="Id "/>
</f:facet>
<h:outputText value="#{cust.registernumber}"/>
</p:column>
<p:column>
<f:facet name ="header">
</f:facet>
<p:commandLink value="See" action="#{customerView.prepareCitizenView()}"/>
</p:column>
</p:dataTable>
</h:form>
ManagedBean: customerView's action method
#ManagedProperty(...)
SearchView searchview;
public String prepareCitizenView(){
this.customer = (Customer) searchview.citizenSearchResultList.getRowData();
if(this.customer != null)
return "citizeninfo";
else
FacesContext.getCurrentInstance().addMessage(null, new FacesMessage(FacesMessage.SEVERITY_WARN, "no data.", "no data"));
return null;
}
ManagedBean: searchView
DataModel citizenSearchResultList;
public DataModel getCitizenSearchResultList() {
return citizenSearchResultList;
}
You can return redirect to same page.
customerView.prepareCitizenView can retruns same page with redirect.
like
return "citizeninfo.jsf?faces-redirect=true";
this "jsf" changes according to what you use
As mehmet cinar stated, the solution is to use a redirect in your navigation outcome. I've had this problem myself.
return "citizeninfo.jsf?faces-redirect=true";
From what I was able to deduce, the reason is that the ajax submit will not contain a ViewState request parameter for the new page. Without the ViewState the first time, things break.
Once you perform a redirect, the redirect will correctly have a Viewstate parameter appended to the request, and buttons can be clicked the first time
If p:commandLink is included within two h:form then action will be invoked on second call.
Check the outer tags of p:commandLink

Getting the filtered list in datatable

I am trying to filter a datatable using filter field in the column and get the filtered list (which populates datatable) and update another component (Toplam TL Teminati and Toplam Dolar Teminati) according to the filtered list's values in my page.
Is there anyway to do this in Primefaces 2.2.1 and JSF 2? If not can you rec commend a workaround for this case?
Thanks in advance.
To give you an example of how I achieved custom filter logic in my Primefaces 2.2.1 dataTable, I am giving you a scaled version of my code.
<p:dataTable value="#{listBeans.beans}" var="bean" dynamic="true" paginator="true" rows="20" paginatorPosition="bottom"
emptyMessage="No Beans" loadingMessage="Loading. . ." selectionMode="single" selection="#{listBeans.selectedBean}"
id="beanList" widgetVar="beanTable">
<f:facet name="header">
<h:panelGrid columns="4">
<h:outputText value="Bean List" />
<p:outputPanel>
<h:outputText value="Year Filter: " />
<h:selectOneMenu value="#{listBeans.yearFilter}"
onchange="yearFilterBtn.jq.click(); refreshFilters();">
<f:selectItems value="#{listBeans.years}" />
</h:selectOneMenu>
<p:commandButton id="yearFilterBtn" widgetVar="yearFilterBtn" action="#{listBeans.filterYears}"
update="listBeansForm:beanList" style="display:none;" />
</p:outputPanel>
<p:outputPanel>
<h:outputText value="Filter By Beanchild: " />
<p:inputText value="#{listBeans.beanchildFilter}" style="width: 150px; margin-right: 4px;" />
<!-- refreshFilters forces the visitor filter to refresh the selection if column filters are selected. -->
<p:commandButton oncomplete="refreshFilters();" value="Filter"
action="#{listBeans.filterBeanchildren}" update="listBeansForm:beanList" />
</p:outputPanel>
<p:commandButton value="Export to XLS" ajax="false">
<p:dataExporter target="beanList" type="xls" fileName="BeanReport"
excludeColumns="0,5,6" postProcessor="#{listBeans.postProcessExcelReport}" />
</p:commandButton>
</h:panelGrid>
</f:facet>
<p:column style="width:16px">
<p:rowToggler />
</p:column>
<p:column filterStyleClass="filtertag" filterBy="#{bean.beanDateDisplay}" filterMatchMode="startsWith">
....
</p:dataTable>
Without really going into too much detail about the managed bean code, the actions of the command button are essentially passing filter arguments to my BO layer that requery the database for the new list of beans. The explicit update of the dataTable component is needed to refresh the data.
You will notice that on the explicit Beanchild Filter button that is not hidden, I have an oncomplete attribute that references a javascript function called refreshFilters(). I can't remember exactly the problem I had, but I think it is a bug in the 2.2.1 version of Primefaces when a column filter value exists and an asynchronous update occurs within the dataTable itself. Here is the javascript function:
function refreshFilters() {
var filters = jQuery('.filtertag');
var uppedOnce = false;
filters.each(function(idx) {
var curEl = jQuery(this);
if (curEl.val() != '') {
curEl.keyup();
uppedOnce = true;
}
});
if (!uppedOnce) {
jQuery(filters[0]).keyup();
}
}
You can see here that I am locating every DOM element that has the class filtertag, which would be the column filters. I am saying that if a value exists in that field after the server action is complete, then I am manually triggering a keyup event as this will "refilter" the column with the previous value from before.
I am not sure if it is necessary in later versions of Primefaces, I am not even sure it is necessary now, so I suggest trying to do this without the Javascript workaround and if you run into problems cooridnating the two then you can consider using the Javascript.
