FillToolItem does not render correct when used inside a container

[gishmo]

Using the ToolBar inside a container which does not have the total width and contains a FillToolItem does not render correct. It seems that the FillToolItem uses the whole screen width when calculating the width.

This behavior is different than it was in GXT 2.2.5.

Update 1:
This happens only when the toolbar - containing the FillToolItem - is placed inside a TabPanel!

Update 2:
After switching to another tab and going back to the old tab, the toolbar gets resized and renders correct.

any ideas?

Forgot to call forceLayout();
