See trace log below.
We currently have the problem that we do not control at which stack level our activities get executed in the EDT.
In this example we triggered a save operation via the GUI IDE. During the execution the progress monitor for providing update for that operation decided to run the SWT event queue where our logic now takes over and tries to save another editor. Unfortunatly the Eclipse logic prevents that.
