Hi Lasantha,
Are you using trunk build of Cayenne? While property access is not yetimplemented, field access should work just fine and should be thedefault. If this is a bug, I'll be happy to look into it. Do you havemore info about the error?
Thanks
Andrus

Hi Cayenne Experts,
I have been working with Cayenne Geronimo integration quite asometime (working with my own speed) ;-) . After introduction ofruntime entity enhancement feature in Geronimo Cayenne also workingfine. So we are almost there :-) .
When am I executing JPA sample application given with Geronimo causesa NPE in Cayenne side. Looks like it is due to the missing feature inCayenne side (according to the Cayenne source code comments). Thissample JPA does not provide field or property level annotations. Soit makes access level to null in Cayenne causes NPE (related to JSR220 - 2.1.1). As soon as I introduce a property level annotation itworks fine. Any ideas comments?
(If this is a missing feature I would be greatful if somebody can fixthis issue ASAP :-) )
Thanks,
Lasantha
