Can't reopen a persisted closed part! [message #638361]

Hi there,

I am kind of a newbie in e4, I hope you can help me out.
I had an app window with a sash that has two parts. I made one of the parts closeable form the e4xmi workbench model editor, then I closed that part when I ran my app.
Now I can't figure a way to get it back! (even if I make remove the "closeable" check again)

I feel the solution may lie in the Lifecycle class, or in the MDirtyable interface... tried to play with those a little but still no result... It is getting really frustrating to get my part back!!
I want my part back!!

Thanks for anyone who can help me out! Really!

Well I guess I solved my problem by removingt he part and adding a new one... But if anyone has an answer to the above (like opening a part programatically), that would be very helpful too!

No - your problem is that e4 restores the workbench state like you left
it the last time the application was run.

If you don't want to have such a save restore you need to remove the so
named deltas. If you search this list you'll find a reply from me
explain the command line options you can use to do so.

Normally if a part can come and go you are not only directly adding the
Part but use a PartDescriptor which is e.g. shown in a Show View menu
and allows you to restore the Part once closed.

If you want to show/hide parts, use the part service.
