How to set selected item in bean in <p:dataList> - jsf

I am using p:dataList because I am developing a PrimeFaces mobile view displaying a list of items. When clicking on any item, another pm:view of the same view should be displayed. But the bean should be notified of the selected item.
Unfortunately I couldn't find a way to update the bean successfully: <p:ajax> inside dataTable throws this exception:
<p:ajax> Unable to attach <p:ajax> to non-ClientBehaviorHolder parent
Using <f:setPropertyActionListener> inside the iterative element fails too because I get:
<f:setPropertyActionListener> Parent is not of type ActionSource
This is my code:
<pm:view id="instrumentsView" >
<pm:content >
<h:form id="instrumentsList" >
<p:dataList var="instrument" value="#{instrumentBean.subscribedInstruments}" >
<h:outputLink value="#newView" >#{instrument.longName}</h:outputLink>
<f:setPropertyActionListener value="#{instrument}" target="#{instrumentBean.selectedInstrument}" />
</p:dataList>
</h:form>
</pm:content>
</pm:view>
Clearly, I am using dataList and outputLink because as far as I understand, they are the components optimized for the use in PrimeFaces mobile lists. But I am available to find other options if necessary.

I found out in the showcase (example titled News) the correct way of handling the problem:
<p:dataList var="instrument" value="#{instrumentBean.subscribedInstruments}" >
<p:column >
<p:commandLink value="#{instrument.longName}" action="pm:newView" update=":compId">
<f:setPropertyActionListener value="#{instrument}" target="#{instrumentBean.selectedInstrument}" />
</p:commandLink>
</p:column>
</p:dataList>

There is a topic explaining this in the primefaces documentation.
Selecting Data (page 124)

http://www.primefaces.org/documentation.html
Here is the content
<h:form id="carForm">
<p:dataGrid var="car" value="#{carBean.cars}" columns="3" rows="12">
<p:panel header="#{car.model}">
<p:commandLink update=":carForm:display" oncomplete="dlg.show()">
<f:setPropertyActionListener value="#{car}"
target="#{carBean.selectedCar}"
<h:outputText value="#{car.model}" />
</p:commandLink>
</p:panel>
</p:dataGrid>
<p:dialog modal="true" widgetVar="dlg">
<h:panelGrid id="display" columns="2">
<f:facet name="header">
<p:graphicImage value="/images/cars/#{car.manufacturer}.jpg" />
</f:facet>
<h:outputText value="Model:" />
<h:outputText value="#{carBean.selectedCar.year}" />
</h:panelGrid>
</p:dialog>
</h:form>

Primefaces datatable update datatable

I have a problem with primefaces datatables. I have one datatable with some entries and a column with a button inside. If the button is pressed a popup is opened with another datatable. The entries in the second datatable are depending on the row in which the button is pressed.
<!-- first datatable -->
<h:form id="list">
<p:dataTable id="list1" var="item" value="#{bean1.itemlist}"
rowKey="#{item.id}" selection="#{bean1.selectedItem}"
selectionMode="single">
<p:column headerText="ID">
<h:outputText value="#{item.id}" />
</p:column>
...
<p:column headerText="Edit Entries">
<p:commandButton value="Edit Entries"
actionListener="#{bean2.updateEntries(item)}" ajax="true"
oncomplete="PF('edit_entries').show()" />
</p:column>
</p:dataTable>
<!-- Second datatable in the popup -->
<p:dialog header="Edit Entries" widgetVar="edit_entries" modal="true"
resizable="false">
<p:dataTable id="list2" var="entry"
value="#{bean2.entriesList}" rowKey="#{entry.id}"
selection="#{bean2.selectedEntry}" selectionMode="single">
<p:column headerText="Entry Number">
<h:outputText value="#{entry.number}" />
</p:column>
</p:dataTable>
<f:facet name="footer">
<p:commandButton value="Save" oncomplete="PF('edit_entries').hide()" />
</f:facet>
</p:dialog>
</form>
Bean2
public void updateEntries(Item selectedItem) {
this.entriesList = this.entriesQuery.getAllEntriesByItemID(selectedItem.getId());//db query could take some time
System.out.println("entrieslist size: " + this.entriesList.size()); //prints the correct size
}
The problem is that there are no entries listed in the popup datatable although there are some in the list after the db query.
Any ideas how to fix this bug?
Thanks in advance!
UPDATE 1:
<!-- first datatable -->
<h:form id="list">
<p:dataTable id="list1" var="item" value="#{bean1.itemlist}"
rowKey="#{item.id}" selection="#{bean1.selectedItem}"
selectionMode="single">
<p:column headerText="ID">
<h:outputText value="#{item.id}" />
</p:column>
...
<p:column headerText="Edit Entries">
<p:commandButton value="Edit Entries" update=":dialogUpdateEntries"
actionListener="#{bean2.updateEntries(item)}" ajax="true"
oncomplete="PF('edit_entries').show()" />
</p:column>
</p:dataTable>
</h:form>
<!-- Second datatable in the popup -->
<p:dialog header="Edit Enries" id="dialogUpdateEntries" widgetVar="edit_entries" modal="true"
resizable="false">
<h:form id="formEntriesList">
<p:dataTable id="list2" var="entry"
value="#{bean2.entriesList}" rowKey="#{entry.id}"
selection="#{bean2.selectedEntry}" selectionMode="single">
<p:column headerText="Entry Number">
<h:outputText value="#{entry.number}" />
</p:column>
</p:dataTable>
<f:facet name="footer">
<p:commandButton value="Save" oncomplete="PF('edit_entries').hide()" />
</f:facet>
</form>
</p:dialog>
You're indeed not updating the data table in the dialog. JSF doesn't automatically update the view on change of the model, you have to explicitly tell the view to do so. You can use the ajax action component's update attribute for this. This takes a JSF client ID which can be found by rules as outlined in this related answer: How to find out client ID of component for ajax update/render? Cannot find component with expression "foo" referenced from "bar".
Given the markup as shown in the question, that'll be
<p:commandButton ... update=":list:list2" />
However, there's another potential problem. You're using <p:dialog modal="true"> inside a form instead of giving the dialog its own form. This way the dialog may not be available in the HTML DOM tree as JavaScript (the one responsible for dealing with ajax stuff) would expect to find it. Giving the dialog its own form should fix this matter. It'll also fix the potential future problems with invoking actions from inside the dialog as handled in this related question: <p:commandbutton> action doesn't work inside <p:dialog>.
<h:form id="viewForm">
...
<p:commandButton ... update=":editDialog" />
...
</h:form>
<p:dialog id="editDialog" modal="true">
<h:form id="editForm">
...
</h:form>
</p:dialog>
Try adding update="list2" to Edit Entries command button (even update="#widgetVar(edit_entries)" should work).
If, because of page layout and structure, you can't target the second datatable using above suggestions, then add styleClass="tList2" to second table, and update it with update="#(.tList2)" on edit button.

PrimeFaces Composite Components: commandLink doesn't work in dataTable

'
<cc:implementation>
<p:outputLabel value="#{cc}"/>
<p> <p:commandButton value="Vedi lista file" actionListener="#{cc.researchFileInDirectory}" update="panelFileLog"/></p>
<h:panelGrid id="panelFileLog">
<p:dataTable var="file" rendered="#{cc.viewFileList}" binding="#{cc.listaFile}">
<p:column headerText="File" style="width:100px">
<h:outputText value="#{file.toString()}" />
</p:column>
<p:column headerText="Link" style="width:100px">
<p:commandLink id="downloadLink" value="download" ajax="false" actionListener="cc.downloadFile">
<p:fileDownload value="#{cc.file}" />
</p:commandLink>
</p:column>
</p:dataTable>
</h:panelGrid>
</cc:implementation>'
This component is called in this page
<l:logFile />
It loads the list of files but when I click on commandLink, it does not call the actionListener method but redirects me to the same page.
Every component that uses StreamedContent does not work in a composite component. For more detailed explained, please read http://jsfcorner.blogspot.be/2012/11/advanced-primefaces-graphic-image.html . Since <p:fileDownload/> is one of them you can't use it.

update primefaces or jsf view after ajax call on submit button

I am trying to update a primefaces form (wizard-first step) after an ajax command button request with no success. The command button that makes the actual ajax call is on a dialog. I would like after submitting the request to force my view to refresh.
The command button deletes a record from a datatable. It works fine, record is deleted but when dialog is hidden the datatable keeps displaying the deleted record. I would like to force it somehow to refresh. Any ideas? Could I do it from my backing bean reviewManagerBean.deleteProtocol() method?
Here is the code (my BackBean is viewScoped):
<h:form id="reviewManagerForm">
...
<pe:masterDetail id="masterDetail" level="#{reviewManagerBean.currentLevel}" showBreadcrumb="false" selectLevelListener="#{reviewManagerBean.levelListener}" >
<f:facet name="header" >
<h:panelGroup layout="block" style="margin-top: 10px;" >
<h:panelGroup styleClass="levelTitle ui-state-default ui-corner-all wizard-breadcrumbs#{reviewManagerBean.currentLevel eq 1 ? 'ui-state-hover' : ''}">
<h:outputText value="1: Protocol picker"/>
</h:panelGroup>
...
<p:messages id="mainMessagesPanel" showDetail="true" closable="true" />
</h:panelGroup>
</f:facet>
<pe:masterDetailLevel level="1">
<p:panel id="panel1" header="List of available protocols">
<p:dataTable id="protocolsDataTable" var="cRProtocol" rowKey="#{cRProtocol.revProtId}" value="#{reviewManagerBean.cRReviewProtocolList}"
widgetVar="protocolsTable"
...
selection="#{reviewManagerBean.selectedReviewProtocol}"
selectionMode="single" >
...
<p:ajax event="rowSelect" listener="#{reviewManagerBean.setSelectedRow}" />
<p:ajax event="rowUnselect" listener="#{reviewManagerBean.unsetSelectedRow}"/>
...
<p:column sortBy="#{cRProtocol.revProtTitle}" headerText="Title" style="width:200px;text-align:center;">
<h:outputText value="#{cRProtocol.revProtTitle}" />
</p:column>
...
<p:column>
<p:commandButton value="Delete" onclick="dlg5.show()"
update=":reviewManagerForm:deleteSingleProtocol"
disabled="#{reviewManagerBean.checkifProtocolIsOpen(cRProtocol)}"
ajax="true" process=":reviewManagerForm:deleteSingleProtocol" />
</p:column>
</p:dataTable>
</p:panel>
...
<p:dialog id="dialog-deleteprotocol" header="Delete Image Type" widgetVar="dlg5" dynamic="true" modal="true" resizable="false">
<p:panelGrid id="deleteSingleProtocol">
<p:row>
<p:column>
<h:outputText value="Id:" style="font-weight:bold; padding-right:10px" />
</p:column>
<p:column>
<h:outputText value="#{reviewManagerBean.selectedReviewProtocol.revProtId}" />
</p:column>
</p:row>
...
<p:column>
<p:commandButton id='protocolDelete'
value='Delete'
action='#{reviewManagerBean.deleteProtocol()}'
ajax="true"
onclick="dlg5.hide()" icon="ui-icon-disk"
update=":reviewManagerForm:protocolsDataTable"
process=":reviewManagerForm:deleteSingleProtocol" />
</p:column>
</p:row>
</p:panelGrid>
</p:dialog>
Your datatable should be re-rendered properly, you would have gotten an exception otherwise (something like component with id :reviewManagerForm:protocolsDataTable could not be found).
This means that #{reviewManagerBean.cRReviewProtocolList} will get called again. You need to remove the item from that list. This is appropriately done from #{reviewManagerBean.deleteProtocol}.
When #{reviewManagerBean.cRReviewProtocolList} is called after the removal, your datatable will get updated.

JSF PrimeFaces overlayPanel submit value

I would like to submit value form jsf page to bean from overlayPanel with checkbox like this:
To show overlay panel and ajax submission I use this code, and see it's OK in debugger:
<p:commandButton id="joinBtn" value="Basic" type="button" disabled="#{dataPropertyCurrent.notJoinable}"/>
<p:overlayPanel id="joinPanel" for="joinBtn" appendToBody="true" dynamic="false">
<f:facet name="header">Details</f:facet>
<p:dataList value="#{treeBean.getDataPropsCouldBeJoinedWith(dataPropertyCurrent)}" type="definition" var="dataJoinVal">
<h:panelGrid columns="2" cellpadding="10">
<h:column>
<p:selectBooleanCheckbox value="#{dataJoinVal.checked}" id="cbID">
<p:ajax event="change" update="cbID" partialSubmit="true"/>
</p:selectBooleanCheckbox>
</h:column>
<h:column>
<h:outputText value="#{dataJoinVal.caption}" />
</h:column>
</h:panelGrid>
</p:dataList>
<!--<p:commandButton value="Apply" id="btnApplyJoin" type="button" process="#parent" />-->
<h:outputLabel value="ID: #{dataPropertyCurrent.joinDataPropertyId}" />
</p:overlayPanel>
But after it when the overlayPanel is hidden and form submit button being pressed with this code:
<p:commandButton value="Apply join" update="joinAccordionPanel,dsAccordionPanelMain" actionListener="#{treeBean.applyJoinOptions}" />
it sets "false" to bean boolean value again.
So how to submit overlayPanel value to bean properly?
PrimeFaces version: 3.5
I've found explanation here: http://forum.primefaces.org/viewtopic.php?f=3&t=30550#p97737:
"If you are using appendToBody, it's strongly recommended to have a form inside the overlayPanel component that wraps all of the input fields and buttons. This is what you have done in your last solution. However, this means that you cannot place the overlayPanel inside another form in the xhtml page because of the limitation on nesting forms. The best solution is typically to avoid appendToBody wherever it's not absolutely necessary."
Edit
I've added <h:form> inside overlayPanel, and now it works fine:
<p:overlayPanel id="joinPanel" for="joinBtn" appendToBody="true" dynamic="true" >
<h:form id="formTmp">
<f:facet name="header">Details</f:facet>
<p:dataList value="#{treeBean.getDataPropsCouldBeJoinedWith(dataPropertyCurrent)}" type="definition" var="dataJoinVal">
<h:panelGrid columns="2" cellpadding="10">
<h:column>
<p:selectBooleanCheckbox value="#{dataJoinVal.checked}" id="cbID">
<p:ajax event="change" update="cbID" partialSubmit="true"/>
</p:selectBooleanCheckbox>
</h:column>
<h:column>
<h:outputText value="#{dataJoinVal.caption}" />
</h:column>
</h:panelGrid>
</p:dataList>
</h:form>
</p:overlayPanel>

prime faces command link ajax not working

I am trying to use Ajax with a command link to update a dialog. Te form doesn't have any id, I am not able to run this page also, it says component with "dialog" not found/doesn't exist
<h:form>
<p:tabView id="tabView">
<p:tab id="tab1" title="Tab 1">
<h:panelGrid columns="1" cellpadding="10">
<h:dataTable value="#{testBean.dataList}" var="data">
<h:column>
<h:outputText value="#{data}" />
</h:column>
<h:column>
<p:commandLink action="#{testBean.loadCommentHistory(data)}"
update="dialog" oncomplete="dlg.show()">
<h:graphicImage url="resources/theme1/images/comments.gif"
styleClass="basicImageStyle" />
</p:commandLink>
</h:column>
</h:dataTable>
<p:dialog id="dialog" header="Dynamic Dialog" widgetVar="dlg">
<h:outputText value="#{testBean.commentHistory}" />
</p:dialog>
</h:panelGrid>
</p:tab>
</p:tabView>
</h:form>
The p:dataTable itself is a container. The p:commandLink is searching within the p:dataTable for an element with an id "dialog".
Solution: add an id to the form and refer to the dialog as ":formid:dialog".
Edit:
The p:tabView or the p:tab is also a container so check the id of the dialog in your browser and use that one. ;-) It should be noted to avoid id's as jdt_id4.
