I get a CyclicReferenceException while using Betwixt to write a bean. We get
this exception on our development server - websphere 5.1, JDK 1.4.2.5, AIX 5.2,
betwixt 0.7, hibernate 3.1. However the same code worked on my local
workstation - webshere 5.1, J2RE 1.4.2 , XP version 5.1, betwixt 0.7, hibernate
3.1. We are using .betwixt files for all bean properties that needs to be
written. Any ideas??
Thanks
Sailesh
