Collection Proxy question

  Hi all,

  We are encountering a problem when using collections with proxy (OJB rc6). 
An object has a mapping with an attached collection as:
 <class-descriptor....>
   ...
   <collection-descriptor
    name="entries"
    element-class-ref="elementClass"
    proxy="true"
    auto-update="true">
    <inverse-foreignkey field-ref="objectId"/>
   </collection-descriptor>
 </class-descriptor>

  In some cases we have to retrieve the object from the database, clear its
collection of entries (by calling entries.clear()), and add new elements (with
entries.add()). With proxy set to "false", the old entries are removed from
the database and the new entries added. With proxy set to "true", the old
entries are no longer deleted from the corresponding table.
  Is there anything we are doing wrong, or this is the correct behavior?

  Regards,

  Bogdan

 Thank you very much for your reply.

Hello,

What API are you using? With RC6, and with ODMG or JDO, auto-update must
be set to false. Also, I suggest setting the refresh flag to true.

Hope this helps,
Luis Cruz
