Kam ChanSubject: NullPointerException when running xQuery using DataDirect xQuery processor
Author: Kam Chan
Date: 25 Jun 2009 12:05 PM
Hi,

I am using SS 2009 XML Enterprise Suite Release 2, build 1386e.

I have an xQuery project, every time I run this using the DataDirect process it error'ed out with the NPE.

(Although running this same xQuery using Saxon 9 processor works, I must use the DataDirect processor)

I have no idea how to workaround this problem. Please Help.

Kam

Hi Kam,
thank you for reporting this problem; would it be possible for you to send us the complete XQuery and source XML to stylus-field-report@progress.com so that we can reproduce in-house?

Thanks,
Alberto
