Hi there!
I have a regular TabLayoutPanel and I'm trying to make the content of
each tab load dynamically when the user clicks on a particular tab. I
tried using a SelectionHandler with no luck, for tab content can't be

Actually i was overridden the onLoad method in which i was calling

Use emulateIE7 in your html page. I personally had limited luck with

Another work around is: frames.
If your underlying layout is in smartgwt, load your canvas piece as
