Fix a bug found from bug126248: Chart error with Scripted Data Source

- Bugzilla Bug (s) Resolved:
N/A

- Description:
Actually bug126248 is not a bug, since it is caused by incorrect configure of POJO file in report design time when using Scripted Data Source. But in investigating it, I find an exception will be thrown when the row count of data set is 0 if using data set in Chart Builder. The bug is fixed by this check-in.
