The more precise check is if
if( ojbFkFields.lenght > refPkValues.lenght )
throw new PersistenceBrokerException("The number of fields in
foreign key is greater than the number of fields in primary key (" +
realObj.getClass().getName() + ")");
Just m2c,

I had this (exactly) stack trace when I made some reference (foreign key)
with two fields mapping for a table that has only one field in primary key.
I think OJB must check if fkfields[].length == pkfield[].lenght, and throw a
better explanatory exception. The code in PersistenceBrokerImpl should be
similar to
// MBAIRD: we have 'disassociated' this object from the referenced
object,
// the object representing the ord is now null, so set the fk to
null.
if (ref == null)
{
refPkValues = new Object[objFkFields.length];
}
else
{
// BRJ: ref may be Proxy
Class refClass = ProxyHelper.getRealClass(ref);
ClassDescriptor refCld =
descriptorRepository.getDescriptorFor(refClass);
refPkValues = brokerHelper.getKeyValues(refCld, ref, false);
}
if( ojbFkFields.lenght != refPkValues.lenght )
throw new PersistenceBrokerException("The number of fields in
foreign key doesn't match the number of fields in primary key (" +
realObj.getClass().getName() + ")");
for (int i = 0; i < objFkFields.length; i++)
{
objFkFields[i].getPersistentField().set(realObj,
refPkValues[i]);
}
Jakob, Armin, Thomas can someone confirm this?

Hi
I'm having some problem when I attempt to store the database.
It's throwing the stack trace following stack trace

The problem happen when at the BrokerHelp
Where the class descriptor class is return 2 primary key
And the identity class return only contains one (which is correct since at
the reference mapping I'm only setting only one)
