Troubles with primefaces p:datatable in combination with p:dialog

2
votes

I've spent hours to solve my problem but unfortunately without success.

I diplay user data in a p:datatable what is working fine. Each row has an p:commandbutton which is supposed to show a p:dialog for editing the selected user. That also works fine. The problem is that the fiedls inside the dialog are not filled with the user data.

Strange is, if I remove all p:inputtext fields from the dialog the remaining h:outputtext fields id="edit_dlg_bngrp" and id="edit_dlg_username" show the data. If i replace them data will be displayed.

You have your dataTable and your dialog inside <h:form id="formTable">. When you evoke dialog you call: update=":formTable:edit".

You need:

  1. Place dialog outside your main current form <h:form id="formTable">
  2. Place a new <h:form> inside your dialog. Ex: <h:form id="dlgForm">. Everything inside dialog will be inside new h:form.
  3. Call update from dataTable like this: update=":dlgForm:edit". You are refering to form inside dialog and panel grid inside form.

Double check your update id. I think your trouble is in:

<p:commandButton value="bearbeiten"  update=":formTable:edit" oncomplete="editDialog.show()" style="font-size:10px;">

I think that your update should be update=":formTable:editUserDialog:edit". Use FireBug or similar to confirm the proper id.
