Hi RAP Team,
Since 1.3.0-M7 Display#asyncExec implementation uses synchronizer,
however this seems to break my unit test. Currently we have code
similliar below:
Button button = ....
SelectionAdapter adapter = new SelectionAdapter()
{
public void widgetSelected(SelectionEvent event)
{
doSomething();
}
};
button.addSelectionListener(adapter);
void doSomething()
{
Display.getCurrent().asynExec
(
new Runnable()
{
public void run()
{
}
}
)
}
I can run my application as usual just fine, but in unit tests in which
I call method 'doSomething' directly the Runnable's run won't get
invoked at all.
Any help would be greatly appreciated.
Thanks & Regards,
Setya

Setya,
your 'workaround' is actually the proper solution to the problem. You
need to spin the event loop to get messages processed. This includes
(a)sync runnables. This behavior now also aligns with how SWT processes
runnables.
Sorry for the late response and the inconvenience.
Regards,
Rüdiger

Rudiger,
Thank you for your clarification. Glad to know that I don't have to hack
anything.
