problem with editing a row in datatable using primefaces - jsf

I have problem with editing datatable with primefaces.
I have tested datatableRowSelection example but it did'nt work.
when I click on the button edit the dialog is displayed but with empty values.
Please Help!
here is my code:
in: ListingPage.xhtml, I have:
<p:column headerText="Edition">
<p:commandButton update="edition" oncomplete="marqueDialog.show()" image="ui-icon ui-icon-pencil">
<f:setPropertyActionListener value="#{item}"
target="#{marqueController.selected}" />
</p:commandButton>
</p:column>
width="400" height="500" showEffect="explode" hideEffect="explode" modal="true" >
<h:panelGrid id="edition" columns="2" cellpadding="4">
</h:panelGrid>
</p:dialog>

See my answer to this question posted shortly before yours...
Cannot update a componet from p:commandLink 'update' attribute,the Link is persent in p:dataTable
The inside of the dialog should be in a seperate form from the dataTable.
EDIT: To clear confusion, DO NOT DO THIS:
<h:form ...>
...
<h:form ...>
...
</h:form>
...
</h:form>
Also, place a form INSIDE the dialog, do NOT encapsulate the dialog:
<h:form ...>
...
<p:dataTable ...>
...
</h:form>
<p:dialog appendToBody="true" ...>
<h:form ...>
...
</h:form>
</p:dialog>
Something like the above should allow the commandButton update to occur to elements WITHIN the dialog.

Update dataTable in a form from a dialog Primefaces

I have a .xhtml file contains 1 form and 1 dialog, as example:
<h:form id="frmMain">
<p:dataTable id="tblFormItem"
widgetVar="wgFormItem">
<p:column>
...
</p:column>
</p:dataTable>
<p:commandButton value="Add value"
onstart="PF('dlg').show()"
oncomplete="PF('dlg').hide()"
action="#{bean.openDialog}"/> <!-- openDialog() will open a dialog has id "dialog" -->
</h:form>
<p:dialog id="dialog"
widgetVar="wgDialog">
<h:form id="dialogForm">
<!-- Some stuffs -->
<p:commandButton value="Save"
update=":messages :frmMain:tblFormItem"
action=#{bean.save}"/>
I got the error Cannot find component for expression ":frmMain:tblFormItem".
I searched and tried everything that I found on Google but it still produces the same error.
Please help me, how do I update the dataTable from commandButton in dialog?

p:commandButton doesn't dislpay p:dialog

i have a problem with the display of a dialog on a click. It's a obvious one but i can't spot the bug. I've been stuck on this for days, it's crazy. Can you help me please.
<h:form id="form">
<p:commandButton
rendered="#{characterBean.characterSession.characterName ne null}"
value="#{characterBean.characterSession.title.titleName}"
icon="fa fa-fw fa-edit" onclick="PF('dlg').show();"
update="#form"/>
<p:dialog id="titleDetail" header="#{i18n['title.yourTitles']}"
widgetVar="dlg" dynamic="true" closable="false" resizable="false"
showEffect="fade" hideEffect="fade">
<h:panelGroup>
<p:messages autoUpdate="true" />
<h:selectOneMenu id="titleSelect" converter="#{titleConverter}"
value="#{characterBean.characterSession.title}">
<f:selectItems value="#{characterBean.titleUnlocked}" var="t"
itemValue="#{t}" itemLabel="#{t.titleName}" />
</h:selectOneMenu>
<hr />
<h:panelGrid columns="2" style="width: 100%; text-align:center">
<p:commandButton value="#{i18n['general.submit']}"
icon="fa fa-check"
actionListener="#{characterBean.updateCharacterTitle}"
oncomplete="PF('dlg').hide();" update="#form" />
<p:commandButton value="#{i18n['general.cancel']}"
icon="fa fa-close" action="#{characterBean.submitCancel}"
oncomplete="PF('dlg').hide();" update="#form" process="#this" />
</h:panelGrid>
<p:remoteCommand name="updateForm()" process="#this" update="#form" />
</h:panelGroup>
</p:dialog>
</h:form>
The core problem is essentially this:
<h:form>
<p:commandButton onclick="PF('dlg').show();" update="#form"/>
<p:dialog widgetVar="dlg">
...
</p:dialog>
</h:form>
The default state of <p:dialog> is hidden.
The onclick shows the dialog.
The update updates the entire content of the <h:form>.
The <p:dialog> is also included in the update.
So, the <p:dialog> gets hidden again.
There are several solutions:
Don't let update include the <p:dialog>.
<h:form>
<h:panelGroup id="outsideDialog">
<p:commandButton onclick="PF('dlg').show();" update="outsideDialog"/>
</h:panelGroup>
<p:dialog widgetVar="dlg">
...
</p:dialog>
</h:form>
Replace onclick by oncomplete as it runs after the update.
<h:form>
<p:commandButton update="#form" oncomplete="PF('dlg').show();" />
<p:dialog widgetVar="dlg">
...
</p:dialog>
</h:form>
Move <p:dialog> outside the <h:form> and give it its own <h:form>.
<h:form>
<p:commandButton update="#form :dlg" oncomplete="PF('dlg').show();" />
</h:form>
<p:dialog id="dlg" widgetVar="dlg">
<h:form>
...
</h:form>
</p:dialog>
or, depending on whether you actually need to update the dialog's contents or not
<h:form>
<p:commandButton onclick="PF('dlg').show();" update="#form" />
</h:form>
<p:dialog widgetVar="dlg">
<h:form>
...
</h:form>
</p:dialog>
The recommended solution is 3.

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.

use <p:commandbutton> in <p:datatable> to show a <p:dialog>

Hello I am trying to implement some primefaces commandbuttons in a p:datatable. My need is almost identical to this post:
f:setPropertyActionListener not invoked
Basically I need to have a column of buttons in a , click on one button will pass the object of the current row to the bean, and a dialog will pop out, showing some information of the chosen object.
The following is the relevant code:
<f:view>
<body>
<h:form id="theForm">
<p:dataTable id="testFailures" value="#{testDetails.report.failures}" var="failure"
styleClass="baseTable">
<p:column id="requestColumn">
<f:facet name="header">
<h:outputText value="Request" id="requestHeaderText" />
</f:facet>
<p:commandButton value="Detail" update="requestDialog"
oncomplete="PF('dlg1').show();" type="button">
<f:setPropertyActionListener
target="#{testDetails.selectedFailure}" value="#{failure}" />
</p:commandButton>
<h:message for="requestDialog" />
<p:dialog id="requestDialog" header="Request Dialog"
widgetVar="dlg1" dynamic="true">
<h:outputText value="#{selectedFailure.request}" />
</p:dialog>
</p:column>
</p:dataTable>
</h:form>
<h:message for="theForm" />
<h:message for="responseDialog" />
<p:dialog id="responseDialog" header="Request Dialog"
widgetVar="dlg2" dynamic="true">
<h:form>
<h:outputText value="#{selectedFailure.request}" />
</h:form>
</p:dialog>
</body>
</f:view>
I tried to put the dialog in different positions (see my "dlg1" and "dlg2"). But neither works. No dialog showing. does not show anything either. And I don't see any error message in the browser's console window. (I think there is a exclamation warning).
I have tried debug mode, and set method for the property "selectedFailure" is not called.
Try to remove type="button" from your commandButton and it should work. Also dialogs should not be placed inside dataTables so the position of "dlg2" is more correct.

f:setPropertyActionListener not invoked

I am trying to move a p:dialog out of a h:form, because I have read that this is the preferred way (however I'd like to understand the reason, because my p:dialog inside a form works well in my application).
The only difficulty is that the dialog title needs to be updated dynamically. The dialog is shown when a button in a p:dataTable is clicked.
Here is my old xhtml (before the changes), that's working fine:
<p:dataTable var="event" value="#{eventBean.lazyModel}" selection="#{eventBean.selectedEvent}" />
...
<p:column headerText="#{msgs.Persons}">
<p:commandButton value="#{msgs.ViewPersons}" update=":viewPersonsForm" oncomplete="viewPersonsDlg.show()">
<f:setPropertyActionListener value="#{event}" target="#{eventBean.selectedEvent}" />
</p:commandButton>
</p:column>
</p:dataTable>
<h:form id="viewPersonsForm">
<p:dialog modal="true" widgetVar="viewPersonsDlg" dynamic="true" header="#{eventBean.selectedEvent.name}" >
...
</p:dialog>
</h:form>
And here is the new xhtml, with eventBean#setSelectedEvent() that is not invoked.
<p:dataTable var="event" value="#{eventBean.lazyModel}" selection="#{eventBean.selectedEvent}" />
...
<p:column headerText="#{msgs.Persons}">
<p:commandButton value="#{msgs.ViewPersons}" update=":viewPersonsDlgId" oncomplete="jQuery('#viewPersonsDlgId .ui-dialog-title').text('#{eventBean.selectedEvent.name}');viewPersonsDlg.show()">
<f:setPropertyActionListener value="#{event}" target="#{eventBean.selectedEvent}" />
</p:commandButton>
</p:column>
</p:dataTable>
<p:dialog modal="true" id="viewPersonsDlgId" widgetVar="viewPersonsDlg" dynamic="true" >
...
</p:dialog>
So, again, why in the second scenario eventBean#setSelectedEvent() is not invoked? And, if possible, why the first scenario is not optimal?
It is not restricted to use p:dialog inside a h:form since it can work in some cases, but most of the time you will find yourself struggling with some unexpected behaviour with that, here are some explanations :
Why not to place p:dialog inside h:form 1
Why not to place p:dialog inside h:form 2
The problem in your case is that jQuery method in oncomplete is called before the value is set with f:setPropertyActionListener. To avoid this use the same solution as you used in your first case. So :
<p:dataTable var="event" value="#{eventBean.lazyModel}" selection="#{eventBean.selectedEvent}" />
...
<p:column headerText="#{msgs.Persons}">
<p:commandButton value="#{msgs.ViewPersons}" update=":viewPersonsDlgId" oncomplete="viewPersonsDlg.show()">
<f:setPropertyActionListener value="#{event}" target="#{eventBean.selectedEvent}" />
</p:commandButton>
</p:column>
</p:dataTable>
<p:dialog modal="true" id="viewPersonsDlgId" widgetVar="viewPersonsDlg" dynamic="true" header="#{eventBean.selectedEvent.name}" >
...
</p:dialog>
No need to use jQuery here.
I had the same problem (pf 3.5):
<p:tabView id="cashFlowTabContainer" style="width:100%" activeIndex="0"
widgetVar="cashFlowTabContainerVar">
<p:tab title="#{labels['cashflow_incoming']}">
<p:outputPanel id="incomingPanel">
<p:dataTable value="#{cashFlowController.incomingCashFlows}"
var="cashFlow">
<p:column headerText="#{labels.cashflow_actions}">
<p:commandButton value="Edit"
action="# {cashFlowController.editIncoming}" update="#form" oncomplete="editInputVar.show();">
<f:setPropertyActionListener value="#{cashFlow}"
target="#{cashFlowController.selectedIncoming}" />
</p:commandButton>
</p:column>
and this was my dialog:
<p:dialog id="editInput" header="Dynamic Dialog"
widgetVar="editInputVar" resizable="false" draggable="false"
modal="true">
<p:panel>
<h:panelGrid columns="2" cellpadding="5">
...
<h:outputText value="#{labels.cashflow_description}:" />
<h:inputText
value="#{cashFlowController.selectedIncoming.description}" />
So... This way the setter was NEVER called. Then I noticed that if I emptied the dialog the setter was called.
So I solved it by putting a "rendered" statement on the panel:
<p:dialog id="editInput" header="Dynamic Dialog"
widgetVar="editInputVar" resizable="false" draggable="false"
modal="true">
<p:panel **rendered="#{cashFlowController.selectedIncoming != null}"**>
<h:panelGrid columns="2" cellpadding="5">
I guess there's a null pointer that is not logged anywhere... anyway this way it works :)
