Hi,

I'm running 4 update panel on a page, only one showing at a time
(using css )
the panels are all being updated on a timer tick ( 1 timer 4 updates)

they all query rss url to update their content

the problem is that sometimes i get the error
Sys.InvalidOperationException: Could not find UpdatePanel with ID
'xxxx'. If it is being updated dynamically then it must be inside
another UpdatePanel

looks like it's a client side error , i just don't know why or how it
happens

any clue would help

Thanks
