zhifu Jin updated RF-12268:
---------------------------

    Workaround Description: 
I just changed packed.js by myself, like below:

if(R[0].getReadyToSubmit() ){
    Z=T=R.shift();
    N.debug("richfaces.queue: will submit request NOW");
    var a=T.options;
    a["AJAX:EVENTS_COUNT"]=T.eventsCount;
//modify by zhifu for "element is null" bug on 09 May, 2012
+    if(T.source && (typeof T.source==="object" ||  (typeof  T.source === "string" && document.getElementById(T.source) ))){
        E.ajaxContainer.jsfRequest(T.source,T.event,a);
+   }else{
+        T = null;
+        return;
+   }  
//modify end
    if(a.queueonsubmit){
        a.queueonsubmit.call(Z)
    }
    J("onrequestdequeue",Z)
}};
