DisclosurePanel (gwt) in Window (smartclient)

[jsanroman]

Hello

I have a window with two components, DisclosurePanel from gwt and a ListGrid from smartclient. I would like that ListGrid fill the window (with a top margin), and DisclosurePanel is positioned with absolute position above the ListGrid.

The problem is that when I try to deploy the DisclosurePanel there is a layer that contains it (layer is generated by smartclient) does not change its size (its size is always of the compressed DisclosurePanel) then DisclosurePanel is never shown completely.

Is possible to insert DisclosurePanel (gwt) with position absolute in Window (smartclient)?

Thanks and sorry for my English
