Hi Brian,
I use JBoss AS 7.1.1 and the JBoss JSF Implementation 2.0.9.
Honestly, I don't think it is because of different containers we are using. It is more a bug I produced myself..
Well, I have a suspicion..:
I posted only the relevant parts of my source code (what I thought are the relevant parts) , because I didn't want to confuse everybody with to much source code ;-). Now, I'd like to share the whole source code with you because there must be somewehere else a bug I cannot find. I guess something else causes the effect I am now asking for an idea. Actually, I guess some ui components gets rendered which should not be rendered.
The following xhtml page shows a calendar component and a data table initially. Whenever the user selects a date, a JPA query gets executed with the date as filter criteria. The datatable gets updated and rendered again. So far so good. This works as expected.
Now, I observed that the datatable gets rendered again when the user clicks on the command link to edit the selected row. And this should not be the case. Because this event loads the data again, but not for the selected date. It loads the data for the current date which is wrong! This jpa query, returns no result! So, I guess the empty data gets propagated via setpropertyActionListener and that is the reason for displaying no data in the popup panel. However, I can't explain why the log message of participationController.setEditedParticipation() will not be logged.
Any ideas on that ?
Here is the whole source code:
