EDIT

Ja, das ist ein wichtiges Thema. Insbesondere wenn man nightly häufig neuinstalliert, bekommt man beim ersten mal immer Probleme, weil er irgendwas öffnen will was irgendwo wohl mal geöffnet war, obwohl ich in der Zwischenzeit der Editor schon sehr häufig mit anderem Layout geschlossen habe.
Ich habe das noch nicht systematisch untersucht, aber sollten wir machen.

This is a general problem when working with >1 installations of the editor. We should try to store instance specific xmi files

This article might help. Seems like you can programmatically store and load the application model.

After implementing #6847 the launch flag -clearPersistedState does not seem to work anymore. During development you have to manually delete the workbench.xmi in {workspace}/.metadata/.plugins/org.eclipse.pde.core/.bundle_pool/configuration

Maybe we can implement a switch for dev and release

Andreas:

"[Im Editor] der noch keine Verbindung zu einer DB hat, wird versucht, einen Nameeditor zu öffnen. Das scheint mir nicht sinnvoll. Es sollte erst nach öffnen der Verbindung passieren.

Wenn ich dann in den ausgegrauten Nameeditor klicke, bekomme ich zudem folgende NPE:

Ich habe das jetzt nochmal beobachtet. Es passiert immer, wenn man mehrere TaxEditor Instanzen parallel auf hat. Dann übernimmt er die Information von der bereits geöffneten Instanz. Da müssen wir uns noch was ausdenken."
