Having problems with the EJBBeans middlegen created I took a look at
entity-cmp-20.vm

shouldn't it be ( _!_$plugin.fkcmp)

#if((!$column.fk || !$plugin.fkcmp))

instead of

#if((!$column.fk || $plugin.fkcmp))

/**

* Returns the $column.variableName

* @todo support OracleClob,OracleBlob on WLS

*

* @return the $column.variableName

*

#if($column.pk)

* @ejb.pk-field

#end

If you explain the symptom of your problem, I might get a clue about
what the bug is :-)

What's wrong?

Sure.

If i have a 1-to-many relationship 1 User {user_id,name} to many
Reservation{reservation_id, user_id}

Im seeing both a String: getUserId and a UserLocal: getUser in the generated
ReservationBean.
Is this the intended behaviour??

however when jboss tries to create a new Reservation i get a duplicate key
exception because it tries something like
create Reservation(reservation_id, user_id, user_id) value (?, ?, ?)

perhaps its a Sapdb specific problem not accepting the same column twice in
a create statement.
