How to handle exceptions related to the rendering of charts
ganesh1984
Hi All,
I am using BIRT 2.3.2 with hibernate datasource. i am able to create reports successfully. In all my reports i am having a table at the top of the report and a chart at the bottom of the report.
Every thing works fine if the result set returns more than zero records. I am getting exception if the result set returns zero records (i.e result set is empty). Chart is not getting rendered. it throws exception.
If i remove chart from the report, i wont get any exception even though if the result set is empty. So the problem is with Chart...
Note: This is happening only with HQL(hibernate query). Everything works fine when i use JDBC datasource(native SQL queries).
I couldn't find any solution for this. Now at least i want to catch the exception thrown.
please tell me, how i can catch exceptions related to chart rendering.
waiting for your reply...

BIRT 2.5 has a feature to handle this with charts. You can set a message/visibility when the chart data does not exist. What version of BIRT are you using?
