Hello,
I am trying to work with different threads, to use
DeferredTreeContentManager and other tasks which use Jobs API. I am
confronted by difficulties.
Classes extending SessionSingletonBase, resources
(RWT.NLS.getISO8859_1Encoded( BUNDLE_NAME, clazz )),
Dysplay.getCurrent() cannot be used from these threads and jobs.
I've created my own thread system, which sets all session data to thread
when it starting and it works correctly, but what I should do for
threads creating from not my code (e.g. DeferredTreeContentManager)? How
to work with resources form non-UI threads?
Thanks.

Hi,
I took a short look at the DeferredTreeContentManager. From what I've
seen there, it could be a bug in startFetchingDeferredChildren how the
Job is beeing created (I think it should be created Session-Context
aware, which is not the case), but this still needs more investigation.
So feel free to file a bug on this to track the progress on this
problem.
Ciao
Frank

Thanks, Frank.
Bug 227063 is created.
I want to understand in details how to use Threads and Jobs correctly in
RAP. How to get Display and work with SessionSingletonBase in them.
Maybe you can show small code example?
For example I am creating new thread:
Thread t = new Thread(new Runnable()
{
public void run()
{
PlatformUI.getWorkbench().getDisplay().syncExec(new Runnable()
{
public void run()
{
(new MyDialog()).open();
}
});
}
});
This code fall on line PlatformUI.getWorkbench() because Workbench
extends SessionSingletonBase and need session context to get instance.
What the general resolution for situations similar to current example?

Hi,
note that you need to map the thread you are executing somehow to the
session to which the thread should belong. This is since you have n
sessions on a server and the single thread you are executing doesn't
know out of the box anything about those sessions. So here is your
modified example snippet that shows how this can be achieved:
final Display display
= PlatformUI.getWorkbench().getDisplay(); // <-- this assumes we are
in the UI Thread
Thread t = new Thread( new Runnable() {
public void run() {
UICallBack.runNonUIThreadWithFakeContext( display, new Runnable() {
public void run() {
display.syncExec( new Runnable() {
public void run() {
( new MyDialog() ).open();
}
} );
}
} );
}
} );
Ciao
Frank
