Hi all,
I got exception on my nested conversation. The partial codes are listed as follows. When I
click selectOneRadio on @Begin(join=true), I got the exceptions. I appreciate any helps.
Thank you in advance. I use seam1.0.1, myfaces, facelets, and jboss4.0.4GA.

| onclick="submit()" immediate="true"
| valueChangeListener="#{studyEditor.propertyChanged}"
| layout="pageDirection">
| <f:selectItems value="#{studyEditor.propertyItems}"/>
| </h:selectOneRadio>

| isNew = true;
| study = new Study();
| study.setModifiedBy(user);
| study.setModifiedOn(new Date());
