             Summary: @MapsId will replace the real column in schema
                 Key: OPENJPA-2485

          Issue Type: Bug
            Reporter: chainho

I found an issue like this:
OpenJPA will use the value of MapsId annotation replace real column in schema. 
use the attach file "", run, you will get the error message:
<openjpa-2.2.0-r422266:1244990 fatal general error> org.apache.openjpa.persistence.PersistenceException:
Unknown column 'empPK' in 'field list' {prepstmnt 14439476 INSERT INTO DID1bDependent (empPK,
name) VALUES (?, ?) [params=?, ?]} [code=1054, state=42S22]
FailedObject: com.sun.ts.tests.ejb30.persistence.derivedid.ex1b.DID1bDependent@cf7fd0

the empPK isn't the real column in schema, but it will used in sql statement
