Hi,
My RAP application uses UICallback.activate() to asynchronously update
the browser UI from a server thread, using Display.syncExec(). The
syncExec() runnable ultimately calls UICallback.deactivate() to release
resources before the thread exits.
I noticed that if a user closes the browser window before syncExec() is
called, the syncExec() method never returns and the thread gets stuck in
that call, causing resources to be lost over time.
How can I catch this occurence? For example, is it possible to get a
list of active UICallback ids from the HTTP session object so that I may
abort the thread before calling syncExec()?
Thanks.

Hi,
to me this seems as if this could be a bug. As soon as the session times
out all pending runnables for syncExcec should probably interrupted and
adding new ones to the display should throw an exception. Could you file
a bug for this?
Ciao
