ProgressBar not updating when running a job the second time [message #110763]

Hi,

I tried some tutorial on eclipse jobs and displaying its progress in a
progress bar. I am setting the job to a user job so that the progress is
displayed. It works fine for the first time. The progress bar shows up and
shows the progress in its main and in its detail part. When starting the
job the second time the main part keeps showing the progress but the
detail part freezes as i open it.
Here is some code to show what i am doing:

button2.addSelectionListener( new SelectionListener()
{

@Override
public void widgetDefaultSelected( SelectionEvent e )
{
// TODO Auto-generated method stub
}

@Override
public void widgetSelected( SelectionEvent e )
{
Job job = new Job( "My Job" )
{
@Override
protected IStatus run( IProgressMonitor monitor )
{
try
{
monitor.beginTask( "Printing messages", 10 );
for( int i = 0; i < 10; i++ )
{
System.out.println( "Hello World (from a background job)
" + i );
try
{
Thread.sleep( 1000 );
}
catch( InterruptedException e )
{
// TODO Auto-generated catch block
e.printStackTrace();
}
monitor.worked( 1 );
if( monitor.isCanceled() ) return Status.CANCEL_STATUS;
}
return Status.OK_STATUS;
}
finally
{
monitor.done();
}
}
};

job.addJobChangeListener( new JobChangeAdapter()
{
public void done( IJobChangeEvent event )
{
if( event.getResult().isOK() ) System.out.println( "Job
completed successfully" );
else
System.out.println( "Job did not complete successfully" );
}
} );
job.setUser( true );
job.schedule();
}
} );

The code works fine in a RCP example. So I would like to know if I am
doing something wrong and its maybe just a coincidence that it works in
RCP.

Thanks in advance

Gunnar

Hi Gunnar,

I can't find anything wrong with your code. I've managed to reproduce
exactly what you described. Please file a bug for easy issue tracking.

Best,
Ivan
