Re: Problem with ListView and Feedback Panel

Hi,

 I'm running Wicket 6.3 and have an approval page where a user can approve
 certain accounts that a user requests. The form on the page has several
 ListViews that may or may not be visible. On each list view, the list item
 has a radio button where the approver can set the approval to yes or no.

 My problem is with the Feedback Panel. I'm setting the approval radio
 button
 to required if the corresponding ListView is visible. That works. If I
 don't
 select anything, the page doesn't do anything on submit as the form didn't
 validate. This is correct. But the Feedback Panel doesn't show anything
 either. It used to - under 1.5 I believe, I'm not quite sure when exactly
 it
 stopped. I can implement onError(), but there I can only give a generic
 error message like Something didn't validate in the form. The session
 feedback messages are empty.

 After combing through the user forum, I found that
 listView.setReuseItems(true) should solve the problem. I tried that, and
 miraculously my feedback messages all show. But now I have the problem that
 with the reuse my list view data is not behaving as it should. I have a lot
 of Ajax interaction on each line, and as the ListView is reusing its stuff,
 it doesn't work as intended anymore.

 Long story short, is there any way to get my Feedback Panel working again
 without listView.setReuseItems(true)?


Yes. You may use getPage().error(...) instead of
somethingInsideTheListView.error()
The problem is that the component inside ListView is replaced with a new
one if reuseItems == false and since Wicket 6.0 the feedback messages are
kept in component's metadata.



 Thanks,
 Natalie

Ok, I understand the philosophy behind it. 

My problem is that I'm not generating error messages myself, but rely on
Wicket for 2 things. In the ListView my radio button has setRequired(true)
and my DateTextField has a PatternDateConverter, so how do I pull the
validation error messages out for those and put them on the page?

Hi Natalie,

you should try to make your components ready to be used in ListViews.
If you're chaining your models correctly, there's no why 
ListView#setReuseItems(true) should be a problem.

Sven

I probably wasn't precise enough. The components in the ListView are still
working fine. But I have an AjaxCheckBox outside of the ListView that gives
me Select all functionality. I added the web markup container that wraps
the listview to the ajax request target, but it doesn't update anymore after
I reuse listview items.

In the end I think I have to use some other repeater to make that work,
thanks for the help, though!
