Re: [Wicket-user] add feedback message during component construction ?

[Nick Heudecker]

I've run into this problem before as well.  Is there a better way to support this?

Yes i see it now the IFeedBack instances do get a call first that will initialize them before youre onBeginRequest is called
But now i have thought about it more. That is also a wrong place. Because you are already in the response phase there. And you shouldn't
alter things in the response phase.

I currently see only one solution. Give a page or the FeedbackMessage instance to youre panels constructor.
(or set it at one point as a threadlocal or something)

The call sequence is:

   onGetObject();
   onGetObject();
   onGetObject();
    ... several times...
   onBeginRequest() where settting error message
   onGetObject();
   onGetObject();
    ... several times...

Since onGetObject() only check null for messages:
   if (messages == null)
   {
       //get fillter messages from page
   }
   return messages;

so, only the first invocation of onGetObject() actually get messages from page.

onBeginRequest should work i think
Can you set 2 breakpoints? One in that onBeginRequest where you set the error message
and one in FeedBackMessageModel and then the public Object onGetObject(final Component component) method

Dear all,

    We have several Panels  need to add error message while constructing:

public MyPanel(MyData data) {
    //some process.....
    error(errorMessage);
}

However, panel can't find parent Page yet. I also tried adding error message
in onBeginRequest(), but it didn't work.

Is there any way to add feedback message ?

Thanks in advance
