Hello,

We have a prototype with eclipse 3 on top of sirius which creates a new project and opens a window, the window is almost empty but it works fine for a demo.

We are porting this prototype to eclipse 4 and after porting some Wizard code to Open an existing project we are seeing an IllegalStateException after completion of the wizard:

java.lang.IllegalStateException: Workbench has not been created yet.

I've searched the code an on internet and it could be that I am not calling PlatformUI.createAndRunWorkbench, this used to be called in an Application startup in eclipse 3 but I'm not sure of the corresponding concept with eclipse4.
Any help appreciated!
