I've found solution
. The problem is jqery problem. I had in my jqery code : var $aikQuery = jQuery.noConflict(); I have used aikQuery instead of $, but this construction no longer works in new jquery. Why? I don't know. I had to remove this construction from my code and now is ok.
Strange is that when i use 1.5.1 jquery in my component and PF from snaphot 3 from 3.3.2011 everything is ok, but when i use new snapshot PF with 1.5.1 everything stops work
. It looks like jqery.conConflict() in jqery1.5.1 makes conflicts
