I need something similar to eclipse IDE, where a portion of the screen is empty when the application starts, and when I select s.t. in another part, an editor part opens in that empty portion representing the selection. Further, each selection opens in a new editor part in the same portion.

I have added an empty part stack, but it does not display and handle well. Is it the way it should be done ?
- the height of the tab bar is too small, and the min/max buttons overlap it.
index.php/fa/12542/0/


- when I minimize that empty stack, I get the following NPE, and the widget that usually contains the restore button is not rendered. Clicking on max seems OK though.
