I've just found a problem on my appli with RF3.3.3 (and certainly RF4 but i 'm currently migrating),
The problem is I've 2 pages opened :
Then, when the user is logged he open the chat and 'forget' it during is navigation on the main page.. like jsf NumberOfview/logicalview is fixed at X, if on the main page user navigate accross X 'views' and the chat popup has no refresh because there is no 'a4:push event'.... popup view become become ExpiredView....
In RF 3.3.3 a4j:push (800ms) don't keep the view 'alive'
Actually as Workaround I've put [RF3.3.3] a4j:poll wich force a rerender and keep the view alive... keep the view in last Numberofview/logicalview
For RF 3.3.3/JSF1.2 :
For RF 4:
Thanks for your help
