Subject Failed to use enhanced Embedded class instance as parameter for query.
Date Thu, 19 Mar 2009 09:31:23 GMT
Hi,
Using Open JPA 1.2.0 and jdk 1.6.0_12 .

Failed to use enhanced Embedded class instance as parameter for query.
If this enhanced parameter instance is replaced inplace instantiated
instance of this Embeddable class then the query works. I tried to
lookout if someone has allready faced this problem and filed a bug but
no luck. Should i file a bug?

org.apache.openjpa.jdbc.meta.ClassMapping.toDataStoreValue invokes
org.apache.openjpa.jdbc.meta.strats.HandlerFieldStrategy.getJoinValue(Op
enJPAStateManager,Column,JDBCStore). In that method from StateManager is
tried to fetch field by index which is wrong, because ClassMapping is
for this Embeddable class which in my case has only one field and index
is three so no field is found giving error:

org.apache.openjpa.persistence.ArgumentException: Field "3" is not
declared in "class org.apache.openjpa.enhance.<package><Embeddable
Class>$pcsubclass", or is not managed.

Terveisin / Best regards
