Java Development Tools

Using JDev 10.1.3.5.0. Yes, it's archaic.

I've spent the past two days trying to get a <af:poll> component to work with no success. I've gone through tutorials and gotten them to work, but my personal use case will not.

A dialog window opens. When this dialog loads, a poll component begins refreshing a progress indicator every 2 seconds. This works; I can see the refresh happening. Inside this dialog, a user then clicks a "Start" button, triggering an actionEvent method.

    public void startAction(ActionEvent actionEvent) {
        // initialize progress indicator's range model to 0
        this.simpleBoundedRangeModel.start(actionEvent);
        // Begin performing a business process.
        ManagementDashboardExport pbm = (ManagementDashboardExport)EL.get("#{ManagementDashboardExport}");
        pbm.exportDashboard();
    }

In that bean, a process runs which then updates the progress indicator's model

    public String exportDashboard(){
        private PollingBackingBean pbm = (PollingBackingBean)EL.get("#{PollingBB}");
        // do a bunch of work and at a certain milestone, set that 20% of the work has been done.
        pbm.getSimpleBoundedRangeModel().setValue(20);
        // continue doing work
        ...
     }

The problem is that at the point exportDashboard() begins, the polling quits! The program keeps running and eventually finishes, but the progress indicator never refreshes.

How can a file download/upload process work, but my process not? This seems like some kind of threading issue. I'm trying to show the progress of a running process. Any ideas on how I can get this to work?

Thanks,
Will
