Gantt chart widget: NullPointerException

[georg.schmiditdesign.de]

With Jaspersoft Studio 6.0.1, I get a NullPointerException when compiling a report containing only a Gantt chart widget.

 

This is the stack trace:

This is the JRXML-Tag:

Any hint on what I could try to change would be great!

Maybe  move the chart to the Summary band and test from there.  I assume that you have a query, etc.

As you can see from the stack trace, the chart is in the summary band.

This is the result from my query, without any NULL values:
