JSF Chart Creator - Problem when setting chart tag's type

[jakorsme]

Works just fine if you use a constant ( "pie" ), in the chart tag's type field.
But if you use a backing beans value, such as #{statistics.stuff} it gives a null pointer exception: (yes I've verified that getStuff in statistics returns the String value "pie" ---

This seems to be a bug, I will fix it in the upcoming release.

We're in the last 10 days of a development deadline and we solved a problem last minute using Chart Creator.

Is there a hack we can do to fix this problem. Or is the fixed release due in a few days?

Thanks,
John

Does anyone else know of any other JSF tag wrappers for JFreeChart, that may be further along in the development cycle?

Thanks,
John

Hi,

The RC for the new version has two more weeks to go.

Maybe you can check out jenia's wrapper.
