Entity Creation Problem
-----------------------
Key: JBAS-167
URL: http://jira.jboss.com/jira/browse/JBAS-167
Project: JBoss Application Server
Type: Patch
Reporter: SourceForge User
Assigned to: Bill Burke
SourceForge Submitter: objectwiz .
When I used the CVS tree build of JBoss "as is" I got
the following error when I created Entity Beans:
java.lang.IllegalStateException: do not call
nextTransaction while not synched!

So I wrote a patch for it and it seems to work. There
may be many good reasons why this isn't a good idea,
but here it is anyway in unified diff. I left my
System.outs in as it will allow the person viewing the
patch to see the behaviour:
