Re: NPE in UIData

[Mathias Broekelmann]

Yes you are right. I just missed that.
It´s fixed now.

Best Regards,

There is an NPE condition in UIData.

setValue() sets _rowStates = null

Nowhere else can _rowStates be set back to something meaningful, and
when it is referenced in places like encodeBegin(), you'll get an NPE.

Patch at the end.
