i'm not sure how you're exactly accessing the various beans n methods, but you
mention something that will point to the solution:

I suspect that when you call the 'getAddenda()' method from another bean, the
methods on that bean require a transaction. You can check your configuration
for this.
However, I'm not sure, but I suspect that servlets (e.g., JSP pages) do not
wrap entire methods in a transaction. You'll have to do this yourself.
I was running into the same sort of problem running JunitEE tests. I had to
augment my JunitEE tests with something like the following (code example not
complete):
| Context ic = new InitialContext();
| tx = (UserTransaction) ic.lookup ("java:comp/UserTransaction");
| tx.begin();
|
| AccountLocal lObj = home.findByPrimaryKey(objKey);
| AccountValue vObj = lObj.getAccountValue();
| tx.commit();
|
this is because I had created value objects for another bean (1:n) related to
Account. sooo, the 'getAccountValue()' method also retrieves value objects for
the Account children, all in one method call.
