Hi,
I have developed a empty birt report that calls the initialize event handler for the report. This event handler dynamically creates the DataSource, Dataset and Report contents. I am currently testing on a Tomcat server using the Birt Runtime 2.6. I ran a batch file to call my report 40 times one right after another and all of the reports were created successfully. If I try to load 8 files asynchronisly I get random errors like "Can not load the report query: 372. Errors occurred when generating the report document for the report element with ID 372. ", "Page hint could not be loaded", and blank pages are just a few. Sometimes all of the reports are created successfully. I am confused why these errors are happening. Has anyone had simular issues with Birt? Thanks in advance with any suggestions that you may offer.
Thanks,
Marc

Marc,
What version of BIRT are you using and are you using the viewer?
Do you get the same set of errors if you do not use an event handler?
