Steve,

if you where able to figure out what causes the problem could you please create a jira issue for us. It would be appreciated if you could also attach a test case to the new issue.

Ralf,

Thx for your response. I think you are right. I will try later today. In my other model those flags are different.

Hi Stephen,

can you try to remove lazy="true" and dirthy="ignore" to see if that changes anything. One more thing to try is using a cache for the entities involved.

For some reason I can not get self-referential model case to work. I have this working for another set of classes. I keep getting a read lock exception.

Nested error: org.exolab.castor.jdo.DataObjectAccessException: Field access error: FieldMolder for com.opendemand.jdo.WebResource.webResourceBranches of type com.opendemand.jdo.WebResourceBranch access resulted in

java.lang.IllegalStateException: Transaction org.castor.persist.LocalTransaction
cont...@b52a28 does not hold the read lock: com.opendemand.jdo.WebResource/314/3.

I am using castor 1.01.

Does anyone know what might cause a read lock exception in a self-referential model case.
