NPE After adding @RequestParameter to SESSION bean

lowecg2004 Dec 4, 2006 12:47 PM

I added a @RequestParameter to a SESSION scoped bean and this now occurs at session destruction:

I've moved the @RequestParameter to an EVENT scoped bean and all is well, but I thought I'd raise it anyway as it was an NPE.

This is not yet fixed!

I'm trying to call an SFSB method as a page action with @RequestParameter. Some of the request parameters are actually empty, e.g.:

<input type="hidden" name="adresseUmsatzsteuerIdentNummer" value="" />

Could this be the source of the problem?

Regards

Felix

P.S.: This used to work under 1.0.1.GA.

Sorry, false alarm!

This is an icefaces bug.
