StackOverFlowError in DatabaseField.java?

Question

Hello, I apologize for the length of this post, but I want to make sure you understand exaclty what's going on by providing you with as much information as possible.
I am fairly new to Toplink and ADF, but I have successfully completed several tutorials, and I have gone through the entire SRDemo several times with no errors that I couldn't resolve easily. However, I started building a new JSF (ADF and Toplink) project (using Jdeveloepr 10.1.3.3) using the SRDemo as a guide, and I have run into a StackOverFlow error that I am having trouble resovling.
Let me explain where I am in my project.
My DBA set up a 10gR2 database that that contains 34 tables. I used Jdeveloper to create Toplink POJOs for all 34 tables. I then created an EJB Session Bean, and just like in SRDemo, I created the Data Controls. Now at this point everything has gone smooth with the exception of some 'multiple writable mappings' in the Toplink map that I resolved (leaving them unresolved does not effect the problem).
I created a new JSF JSP called test.jspx allowing the wizard to automatically epose UI components in a new managed bean. Then, from the Data Control pallette I drag a collection over to my page and create an ADF table. So far so good.
I then run the test.jspx page using the embedded OC4J server. When the page loads in the browser I get the following error:
1. JBO-29000: Unexpected exception caught: javax.ejb.EJBException, msg=java.lang.StackOverflowError
2. java.lang.StackOverflowError
This in itself tells me nothing, so I check the embedded oc4j logs (log.xml) and I find the following:
<PAYLOAD>
<MSG_TEXT>[ODPublicFacade:public java.util.List olvims.dispatch.datamodel.ODPublicFacadeBean.findAllTransactionHistory()] exception occurred during method invocation: javax.ejb.EJBException: java.lang.StackOverflowError</MSG_TEXT>

I have tried deleting the project and recreating it from scratch, but I recieve the same message each time. 
Oh one more thing, this error occurs no matter which data control I use.
Has anyone seen this before and/or have any information that might help me resolve this error?
