All context informations are temporary and not saved (most of them could
be saved at all).
You store informations directly in the MPart associated with your part
by creating something like this in your class
class MyPart {
@Inject
public MyPart(MPart p) {
....
}
@PersistState
void persist(MPart part) {
part.getPersistedState()
}
}
So when you create you part using the handler before showing it I'd also
set the informations instead of using the IEclipseContext.
The other option you have is to create an MInputPart which has a url field.
You better ask e4 questions on the e4 newsgroup.
