For the my class:

class CGroupPerson : public VDK_BaseObject
{
  public:
      VDK_ObjectPtr        mGroupPtr;
      VDK_ObjectPtr        mPersonPtr;
      VDK_ULLONG           mGP;
 
   public:
     CGroupPerson ()
          :    VDK_BaseObject( "GroupPerson" ),
               mGroupPtr( "GroupPtr", NULL, kFBL_CASCADE ),
               mPersonPtr( "PersonPtr", NULL, kFBL_CASCADE )
               mGP( "GP", fUnique )
      {
          // next call make field to be calculated
          mGP.SetMethod( "some formula here" );
      }
};

I've tried all of these:

    mGP.SetMethod( "BitAnd( shiftleft(mGroupPtr,32), mPersonPtr" );
    mGP.SetMethod( "BitAnd( shiftleft(mGroupPtr,32), mPersonPtr)" );
    mGP.SetMethod( "BitAnd( shiftleft(GroupPtr,32), PersonPtr)" );

Unfortunately, I cannot add more than 1 record (whatever the combinaison of
person and group). It always return error 344 (kFBL_FieldIsUnique). Any
idea?
