Checking if Report has fully loaded in Java Project

Question

Morning All,
I hope this isnt another one of my daft questions, but how can I put a listner or determine when a report
has fully loaded.
Im testing out the "Crystal Reports Java Project" and am trying to determine when the report has fully
loaded so that I can dispose of it and close the Frame.
So far I am not having any luck, I have got some listeners checking when the window looses focus
and such but that still doesnt tell me when the report has finished loading.
I also tried useing
viewerFrame.reportViewer.isBusy()
but I am not happy with this, as sometimes it returns the correct "true" result while its loading, but then other times it says "false" when clearly I can see the report is still loading.
A post I found somewhere said that the only way is to determine if the total page count in known, but
I have not worked out how to do this yet, or atleast cant find how to do this.
So..... any ideas how I can be sure the report is loaded so that I can programmaticly export the report
and then close everything up.
Cheers
Darren

If you are programmatically exporting the report, typically the code would look as follows:
reportClientDoc.open(REPORT_NAME, 0);
ByteArrayInputStream byteArrayInputStream =
(ByteArrayInputStream)reportClientDoc.getPrintOutputController().export(ReportExportFormat.PDF);
reportClientDoc.close();
As you can see there is no need to check to see whether the report has finished loading, because the ReportClientDocument deals with that process behind the scenes, and won't close the report until the report has finished processing.
