Navigationpane disappears in a nested SplitPane

[mathias]

Hello, please consider the isolated test case below (smartgwt pro 13d)


If you select the first node in the root tree, the split pane child will show as expected. However, if you then select the second root node, and then back to the first node, the navigationpane of the child splitpane disappears!

Is this a bug, or am i doing something wrong?

Cheers /Mathias

(funnily enough, i don't have this issue in my "real" application, where i instead have fullscreen issues with my nested splitpane for some reason, will i thought i'd post in a separate thread)
