Subject relation "mySequence" already exists
Date Thu, 03 Jun 2010 19:17:49 GMT
Hi all, using OpenJPA 2.0.0 with Postgresql 8.4 JDBC4

I want to create the schema with the following property:
<property name="openjpa.jdbc.SynchronizeMappings"

The entity is defined as follows:

@Table(name = "obj_item")
@Inheritance(strategy = InheritanceType.JOINED)
@SequenceGenerator(name = "obj_item_id_seq", sequenceName =
"obj_item_id_seq", allocationSize = 1)
class ObjectItem ...

it seems that the sequence will not be dropped - so I get the
following exception:
org.apache.openjpa.persistence.PersistenceException: ERROR: relation
"obj_item_id_seq" already exists {stmnt 1834517285 CREATE SEQUENCE
obj_item_id_seq START WITH 1} [code=0, state=42P07]
	at org.apache.openjpa.jdbc.meta.MappingTool.record(

I found a bug here:

Any advice?

Regards Christopher
