Hey all,

i have a problem concerning Display.asyncExe(myRunnable); or in detail
with realm.asyncExe(myRunnable).
I have a database and read some data from it in a Job. I registered my
Model at this job as listener, and when the job is done my model gets the
data from the job. Because i have a WritableList i use:

realm.asyncExec(new Runnable() {
@Override
public void run() {
myList.addAll(partnerList);

fireQueryDone();
}
});

Now my model have to update all views. Therefore as you can see i use
observer pattern and call fireQueryDone(). This call i want to do in my
main thread and not in the job thread, so i want to wait until the
asyncExec Thread is finished and then call it. How can i do that? hope you
understand what i mean.
Thanks alot
Thomas

Hi,

Have you try the synExec( Runnable method).
Normally, you wait until the runnable is executed.

Best regards,
Kévin

Realm has no syncExec() :-( I already tried with exe() but it didnt seem
to work :-(

Hi Thomas,

I don't know if there are different versions - the version
of org.eclipse.core.databinding.observable.Realm I found HAS a
syncExec() method, even though it has only 'protected' visibility.

Maybe there's the rub?

Have your main thread wait on an object and have another method that
performs a notify on the object (postQueryDone()). Then call postQueryDone
instead of fireQueryDone after the addAll call in your sample code. When
the wait in the main thread returns, call fireQueryDone.
