There are a number of cases like this. SplitPanels inside DisclosurePanels for example. Other things inside StackPanels. They didn't work in 1.5 and the ones I have tried still don't work in 1.6.
The problem appears to be because if you add these things to a closed DP or StackPanel, then the panel you are adding to is not attached to the DOM and therefore any widget (like a SplitPanel) which uses absolutely positioned elements has no reference to absolutely position them (and 0% to set widths etc). I first mentioned this in August last year but despite a bump or two, got no reply from the GWT team. Because there was no fix forthcoming or any response at all, I eventually took down the 1.5 version of my web site and put the old 1.4 version back up. I asked again when I discovered the problem still exists in 1.6. No response. I have a quite major project to write in GWT starting Monday, so I will constrain the design so none of the more complex panels get nested inside each other. It's very limiting in a large project, I may have to resort to writing my own versions of things I need. Maybe V2 will fix it.
