I am investigating web client implementation and as far as I understood it works in way request-respose. Client always sends json request and takes json as well. Where is no case when server sends something to the client.

Because of that I interesting in situations like this:

createUI(){
...
Display display = RWT.getCurrent();
new Job(""){
    protected IStatus run(IProgressMonitor monitor) {
        display.asyncExec(new Runnable() {
              // perform some UI modifications (changing labels, etc)
        });
    }
}.schedule(10000L);

Now my code will never called. Is it means that all delayed UI jobs never will be executed? Or I missed something?

Hi Igor,
you are right. If a job is scheduled for execution outside running
request it will be executed with the follow up request. See bug
390329: UIJob is scheduled but not executed on UI Thread
https://bugs.eclipse.org/bugs/show_bug.cgi?id=390329
Best,
Ivan
