I am building an RCP with several perspectives, each of them shown in an own WorkbenchWindow. I want do the following: Ad Startup I give as a commandline argument (-perspective) , which perspective should open. I want only one Window with the given perspective opening at startup time. When closing the workbench, it is not yet determened which perspective will be used next startup. The Problem is that either I can handle this, but then the state of the perspectives is not saved or I can save the state but then always the last saved state is restored. Has anyone a solution for this?

You're seeing the 2 supported behaviours, either we don't save the
workbench state, or we save it exactly.

2 things come to mind

1) on startup look at the argument, and get rid of every
window/perspective that doesn't match. There's a postStartup method in
the workbench advisor

2) don't use save and restore, but on shutdown save each open
perspective as a custom perspective to that ID. Then on startup it
should hopefully open the custom perspective as it was saved on
shutdown. See org.eclipse.ui.IWorkbenchPage.savePerspective()

There might be more options, but I can't think of them
