in what way is it possible to let the EntityManager remove an entity with a LOB property?
We are using EJB3, JBoss 4.0.5 and Postgres 8.2.
The underlying table is creates like this

  | CREATE TABLE patient.incident_entry_binary(
  | 	 binary_content OID
  | );
The database stores the binary data in files and writers only an objectid in the table.
When i try to remove the entity i always get an
anonymous wrote : 
  | 13:26:36,323 ERROR [STDERR] javax.persistence.EntityNotFoundException: deleted entity passed to persist: [lu.tudor.santec.gecamed.patient.ejb.entity.beans.IncidentEntryBinary#]


The part of the entity looks like this:

  | 	@Column(name="binary_content")
  | 	@Lob
  | 	public byte[] getBinaryContent() {
  | 		return binaryContent;
  | 	}

any idea?
