Sometimes on entering a page with a modal panel I became the java script error message 'ModalPanel' ist undefiniert (is undefined).
After activating the modal panel on the page, the panel is not displayed and I've got the following message:
Fehlermeldung: 'ModalPanel.Sizer.INITIAL_MIN' ist Null oder kein Objekt
When I am clearing the cache with CTRL-F5 on client side and try again, the error occurs sometimes and sometimes not.
With the same behaviour the error messages 'RichFaces.tabPanel' ist Null oder kein Objekt (is Null or no Object) and 'RichFaces.panelTabs' ist Null oder kein Objekt (is Null or no Object) occurred sometimes. When it occurred, the travelling throu the rich:tabPanels don't works
Clearing the cache may sometimes helps here too.
I am putting this in one Thread, because it seams to be the same problem. The check with firebug doesn't help, because in FireFox it works fine.
I am using RichFaces 3.3.2.SR1 and PortletBridge 2.0.0.FINAL.
I am facing the same problem with richfaces 3.3.3 Final.
The webApp is working well on all installations but one.
The ajax js libs are not loaded in IE 6 and 8. Access with Firefox is working.
This error occurs with different IE and cache settings.
Before I start to analyze this: Did anybody found a solution for this strange problem in the meantime?
