Error retrieving record through database adapter. (ORABPEL-11614)

Question

Am trying to pass a customer name into a database adapter to retrieve customer info. It is working, but it is also faulting.
When I invoke the process with the name "3M COMPANY", I get the following audit message
[2008/06/05 17:36:01] Faulted while invoking operation "GetCustomerDataSelect_paramName" on provider "GetCustomerData".less

The retrieved data is correct. The Database Adapter is pointing to an AS/400 table which does not have primary keys defined. In the offline database, I've defined CGVMSTCST to be the primary key.
The toplink_mappings.xml reflects that:
<opm:alias>Cstcgvmp</opm:alias>
<opm:primary-key>
<opm:field table="CSTCGVMP" name="CGVMSTCST" xsi:type="opm:column"/>
</opm:primary-key>
The value of this field for 3M is 101 (which was correctly picked up).
Why am I getting a primary key is null error?

Answer 1

I did, but I'm not sure how.
I deleted the Database Adapter and the associated offline file and reran the wizard (having a better idea of how to implement a parameter search) and it worked.
I was not able to identify what was created differently the second time.
