Hi all,
perhaps it sounds a bit odd, but want to restart my application before
it gets visible.
Short explanation: I work on a product where the user can select the
working directory at first startup. This is achieved through a
LifecycleManager (@PostContextCreate), where I raise up a popup dialog.
The dialog is displayed correctly, but now I don't know how to restart
the workbench, since it isn't available. What I have is an
IApplicationContext and a Display. I know that IWorkbench now has a
restart() method, but I can't get an object for it. How can I do this?
Thanks in advance,
Ralf.

Look at the implementation of IWorkbench#restart and do the same, in the
end we are setting some equinox stuff ;-)

Hi,
I see the problem is that what you'd like is to have the
@PostContextCreate return a value. I don't see how you can achieve what
you want in 4.3 without rolling your own E4Application :-(
I think you should file a bugzilla requesting that:
@PostContextCreate returns a int which if not 0 is interpreted as the
return value for IApplication#start
