javax.ejb.EJBException: CMR field value is already loaded

The first time a make a select like "findContactsByLetter", it runs fine and
returns me a list of contacts with the given letter.
The problem is when a make the select again with the same letter, returns
me the following error message:

javax.ejb.EJBException: CMR field value is already loaded

My transaction-type configutation was set to Supports, that is, it
runs in a transaction only if the client already have one.

How can i solve this problem??
Is there a configuration error??

If you call the two methods from e.g. a servlet then put a user transaction around the calls.
