New menu entries in Eclipse 4 RCP application model aren't shown when loading workbench.xmi
I have a simple Eclipse 4 RCP application. The parameter "-clearPersistedState" is explicitly not used to make the window have its size and position restored on a later startup. The problem is that the model persisted to ".metadata/.plugins/org.eclipse.e4.workbench/workbench.xmi" contains the whole application state. when I extend the application's model in a later version by e.g. adding a new menu entry and an associated command, these additions are just ignored if a persisted is found. Using "-deltaRestore" doesn't work either.
How can I ensure that specific parts of the application are always rendered how they are defined in the application model instead of restoring their state from "workbench.xmi"? Is it alternatively possible to just persist/restore the window's size and position?
The initial model:

That's how the menu looks when the saved "workbench.xmi" is loaded:
And this is the menu when I first delete "workbench.xmi" or any startup after that:
Solution
If you just want the position and size saved you could use -clearPersistedState and save the position and size elsewhere.
You can set the size of the main window from the saved data in your LifeCycle class. The @ProcessAdditions method seems to be the earliest you can do this. Something like:
@ProcessAdditions
public void processAdditions(MApplication app, EModelService modelService)
{
MWindow window = (MWindow)modelService.find("main window id", app);
window.setX(saved value);
window.setY(saved value);
window.setWidth(saved value);
window.setHeight(saved value);
