code: public void free()
      {
          if (m_record != null) // First, release the record for this table
          { // Do not free this.getFieldList() (may be current record)
              m_record.setTable(null);    // Don't try to free me
              m_record.free();
              m_record = null;
          }
      }
docs: I'm done with the model, free the resources.
  Note: This does not free the associated record. it just nulls the reference.
  (although freeing the record will free this table).
