E4 Perspective display exception In fragment Project
1、Here is my perspective definition in fragment.e4xmi：
2、Just after the programme has been run：
3、When using extension points to extend Perspective, the display is fine, but only fragment.e4xmi has problems.
I can't really understand why this is happening, whether it's a problem with my usage or something else. For this issue I searched StackOverFlow and couldn't find anything similar, so I think it might be a bug.
When I drag and drop the Perspective Stack, the toggle icon shows up fine, but the "<>" still shows up in "Open Perspective". So I'm assuming that the ToolControl for the toolbar in eclipse is not laying out in time, and I have no idea why it's showing up like that in the "Open Perspective" dialogue box.
