Drop Listener not found exception

[haoues01]

Hi all,
I tried to implement a basic drag & drop but I am facing this problem when droping the value :

javax.faces.el.MethodNotFoundException: javax.el.MethodNotFoundException: Method not found: [e-mail](org.richfaces.event.DropEvent)

Here id my jsp :

.. and my bean

...
public void addPlayer(DropEvent event){
// [DEBUG]
this.log.trace("#================> addPlayer() is processing ...");
Object val = event.getDragValue();
if(val == null)
return;
Member member = (Member)val;


//[DEBUG]
this.log.trace("end addPlayer() <===============================#");
}

...

Environment :

Can't reproduce on the same case.. Please just check spelling.

I changed the jboss-service.xml with the attribute "UseJBossWebLoader" to true and It's working now. Is it normal to do so ?
Now I am facing another issue ... I always get a dragValue to null !
Thanks for your help.

Sorry for the inconvenience, but there is another problem that seems to be a bug; drag & drop within a tabPanel doesn't work at all in IE6. I got a javascript error like "element is undefined ...".

This is a critical stage in my development and I am blocked with theses 2 issues (NULL drag value & javascript error).

Thanks in advance for any help.

Currently, drag n drop between regions, as well as between forms doesn't work. In terms of region concepts, it's correct, because only selected region is processed using ajax request.
However, we'll look for some solution for this problem.
http://jira.jboss.com/jira/browse/RF-961

Until the solution is found, I suggest you not to use dnd between regions (remove regions, or don't use dnd)

The IE6 javascript error is now fixed since I included the whole page in one region.

THanks for your help.
