[SOLVED] RCP: Part stack is removed when last part was closed [message #1413393]

In my e4 RCP application I have defined a part stack, to which I programmaticaly add parts (editors) with the REMOVE_ON_HIDE_TAG tag set. When the last part is closed using the red X on the tab, Eclipse removes the the part stack, so that the next attempt to add a new part to it results in a null pointer error.

As a quick work around I have defined an invisible part below the part stack in the application model. This prevents the stack from being removed, but it still gets invisible, so that the layout changes and I have to set the stack visible whenever I add a part.

Is there a way to tell Eclipse to keep the part stack all the time and that it should stay visible, too?

Thanks
Ulrich

Hi Ulrich,

try adding the tag NoAutoCollapse to your PartStack in the Application
Model. That should do the trick.

Cheers,
Marina
