p:confirm: message attribute not recieve bean value - jsf

My datatable has a 'Delete' button on each data field.
On clicking, a confirm dialog will be shown with message as Are you sure you want to delete 'dataId'?
I tried to use p:confirm and customize it's message attribute.
Problem is that I can't call 'dataId' from data field.
You can take a look at my code here:
<p:dataTable id="trip-dtbl" rows="10"
value="#{tripBean.tripsList}" var="trip">
<p:column headerText="ID">
<h:outputLabel value="#{trip.id}" />
</p:column>
<p:column headerText="Action" >
<p:commandButton icon="ui-icon-trash" update="trip-dtbl"
action="#{tripsBean.removeTrip(trips)}">
<p:confirm header="Confirm Delete"
message="Are you sure you want to delete #{trip.id}?" />
</p:commandButton>
</p:column>
</p:dataTable>
The 'trip.id' displayed in the table column but not in confirmDialog.
Why that happen?

How to create a empty page in JSF app with Netbeans and Primefaces?

I have a app created by JSF using Primefaces templates in Netbeans.
One of the pages is a Create.xhtml to insert new record in a mysql database. This page is called by a button in a footer of a List od records.
The problem that when I select this page, the form is empty, only have title and buttons. The outputLabel and inputText are "hidden" (inspecting the page in browser). But if I select first a record in the List and next the Create page the outputLabel and inputText already are visible, but with values.
I want that when I select the Create page this came in an empty form and when I want insert the values I wanted in database.
The code of List.xhtml:
<h:form id="DistritoCreateForm">
<p:panel header="#{bundle.CreateDistritoTitle}">
<h:panelGroup id="display">
<p:panelGrid columns="2" rendered="#{distritoController.selected != null}">
<p:outputLabel value="#{bundle.CreateDistritoLabel_nomeDistrito}" for="nomeDistrito" />
<p:inputText id="nomeDistrito" value="#{distritoController.selected.nomeDistrito}" title="#{bundle.CreateDistritoTitle_nomeDistrito}" required = "true" />
</p:panelGrid>
<p:commandButton actionListener="#{distritoController.create}" value="#{bundle.Save}" update="display,:growl" oncomplete="handleSubmit(args,'DistritoCreateForm');" action="List.xhtml"/>
<p:commandButton value="#{bundle.Cancel}" action="List.xhtml"/>
</h:panelGroup>
</p:panel>
</h:form>
The code of Create.xhtml:
<h:form id="DistritoListForm">
<p:panel header="#{bundle.ListDistritoTitle}">
<p:dataTable id="datalist" value="#{distritoController.items}" var="item" style="width:50%;"
selectionMode="single" selection="#{distritoController.selected}"
paginator="true"
paginatorPosition="bottom"
rowKey="#{item.id}"
rows="10">
<p:ajax event="rowSelect" update="createButton viewButton editButton deleteButton"/>
<p:column filterBy="#{item.nomeDistrito}" filterMatchMode="contains">
<f:facet name="header">
<h:outputText value="#{bundle.ListDistritoTitle_nomeDistrito}"/>
</f:facet>
<h:outputText value="#{item.nomeDistrito}"/>
</p:column>
<f:facet name="footer">
<p:commandButton id="createButton" icon="ui-icon-plus" actionListener="#{distritoController.prepareCreate}" action="Create.xhtml"/>
<p:commandButton id="viewButton" icon="ui-icon-search" action="View.xhtml"/>
<p:commandButton id="editButton" icon="ui-icon-pencil" action="Edit.xhtml"/>
<p:commandButton id="deleteButton" icon="ui-icon-trash" actionListener="#{distritoController.destroy}" update=":growl,datalist" disabled="#{empty distritoController.selected}"/>
</f:facet>
</p:dataTable>
</p:panel>
</h:form>
So effectively (it cannot be seen in your code since it is not an mcve)
You select something
As a consequence a certain variable is set to be used in the shared 'show'/'edit'/'create' page/dialog
Next you press the create button and the same page/dialog is shown with the content from the selection before.
A simple deduction then is that the 'selected' variable is not cleared in the method that is called when the create button is pressed (#{distritoController.prepareCreate})
Solution:
Clear the variable (e.g. by creating a new empty instance of the object...
Effectively this is not a PrimeFaces problem (same would happen with plain jsf too) and it sort of is not a 'java' problem either but a plain coding issue.

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.

p:dataTable (row selection) selection and pe:inputNumber not working

I have a <p:dataTable > which is updated from a button and is also filled. The data is displayed correctly. But the PROBLEM is that when I click/select any row, NO RESPONSE; previously while being clicked, the row was highlighted, now-> no highlight. I have done this type of design many times but this time the <p:dataTable> is behaving weirdly. I cannot find the root of problem.
My XHTML snippet for table is :
<p:dataTable id="tblSales" rowIndexVar="rowsn"
paginator="true" value="#{invSaleMB.dummyList}"
var="saleObj" selectionMode="single"
selection="#{invSaleMB.dummySaleObj}"
rowKey="#{saleObj.item.itemTypeId}">
<p:column headerText="#">
<h:outputLabel value="#{rowsn+1}" />
</p:column>
<p:column headerText="Name">
<h:outputLabel value="#{saleObj.item.itemTypeName}" />
</p:column>
<p:column headerText="Count">
<h:outputLabel value="#{saleObj.count}" />
</p:column>
<p:column headerText="Unit Price">
<h:outputLabel value="#{saleObj.unitPrice}" />
</p:column>
<p:column headerText="Total Price">
<h:outputLabel value="#{saleObj.total}" />
</p:column>
</p:dataTable>
My backing bean is #ViewScoped.
And another component which is not responding to an update trigger is <pe:inputNumber> and value for this component is 'double'. I changed the <pe:inputNumber> to <p:inputText> and worked well and displayed accurate data.
<pe:inputNumber id="totalCost" disabled="true" value="#{invSaleMB.totCost}" />
The datatable and pe:inputNumber are on same form.
What have you changed between "before" (was working) and "now" (not working)?. You are sure "#{saleObj.item.itemTypeId}" is unique for each element of the table? More code of the page could be useful.
For pe:inputNumber to work remember to include xmlns:pe="http://primefaces.org/ui/extensions" in your html tag.

Unable to get the selected values on Dialog while using ContextMenu with Datatable

I have a requirement where I want the user to move the datatable rows up and down.I thought Context Menu would come handy as there would be a Move up and Move down menu item .For this I tried implementing the context Menu for datatable example from Primefaces Showcase. However I am not getting the selected values from the datatable rows to be displayed on the dialog.
Please find the below code:
<p:contextMenu for="availableCars">
<p:menuitem value="View" update="display" icon="ui-icon-search" oncomplete="carDialog.show()"/>
</p:contextMenu>
<p:dataTable id="availableCars" var="car" value="#{RequestBean.formFields}" rowKey="#{car.car_group}" selectionMode="single" selection="#{RequestBean.selectedField}">
<p:column headerText="Field Label">
<h:outputText value="#{car.car_label}" />
</p:column>
<p:column headerText="Field Group">
<h:outputText value="#{car.car_group}" />
</p:column>
<p:column headerText="Field Name">
<h:outputText value="#{car.car_name}" />
</p:column>
</p:dataTable>
<p:dialog header="Car Detail" widgetVar="carDialog" resizable="false"
width="200" showEffect="clip" hideEffect="fold" id="dialog">
<h:panelGrid id="display" columns="2" cellpadding="4">
<h:outputText value="Car label:" />
<h:outputText value="#{RequestBean.selectedField.car_label}" style="font-weight:bold"/>
<h:outputText value="car Group" />
<h:outputText value="#{RequestBean.selectedField.car_group}" style="font-weight:bold"/>
<h:outputText value="Car Name:" />
<h:outputText value="#{RequestBean.selectedField.car_name}" style="font-weight:bold"/>
</h:panelGrid>
</p:dialog>
Any help would be appreciated.
N.B: I am using PF 2.2.1
It looks like the selection doesn't get sent using ajax - you need to set the onRowSelectUpdate attribute on the data table.
From Primefaces documentation:
In both single and multiple selection options described before, enclosing form needs to be submitted
by user so that the selections would be processed and set to the selection value reference. If you’d
like to execute custom logic whenever the row is selected instantly bind a rowSelectListeneror or define onRowSelectUpdate option.

primefaces popup getting closed

I have to implement the search the functionality in primefaces dialog. After submitiing the search commandbutton the table beside the search needs to get updated. But everytime i am hitting the search button the popup gets closed. Please guide.Below is my code snippet for reference:
......
<p:commandButton id="search" value="Search" actionListener="#{createTicketBaseBean.searchUserFromList}" update="#form" onclick="dlg.show()"></p:commandButton>
</h:panelGrid>
</h:panelGroup>
<h:panelGroup style="float:right" >
<p:dataTable id="table" var="user" value="#{createTicketBaseBean.userList}" selection="#{createTicketBaseBean.selectedUser}" selectionMode="single" rowKey="#{user.email}" >
<p:column headerText="Name" >
<p:commandLink id="nameselect" value="#{user.name}" onclick="dlg.hide()"/>
</p:column>
<p:column headerText="Email">
<h:outputText value="#{user.email}" />
</p:column>
<p:column headerText="Department">
<h:outputText value="#{user.department}" />
</p:column>
</p:dataTable>
Replace onclick in your p:commandbutton with oncomplete. onclick event is happening immediate when button is clicked. As this is AJAX button (in Primefaces this is default) there will be race conditioning between AJAX request and dialog opening. When using oncomplete it will be called after AJAX request is completed.
