any idea ?

thankx

[paranormal]

so I didn't find any solution for this damn problem

but as i think the problem is thrown because the chat portlet in liferay

...................................

what i did is i deleted this portlet and start creating a new one

by using richfaces 3.3.1  and jboss portletbridge 1.0 snapshot

which is the best for liferay

a lot of people talk about running richfaces 3.3.3 with portletbridge 2 final

but it didnt work for me ( the ajax functions )

and the best example for using richfaces and portletbridge inside liferay is

the example which puublished by exadel

http://liferay.exadel.com/web/guest/richfaces-demo

as i think its the best and the only working example with all ajax functions
