Note:(beetle:5197) Dependent Resultsets of DeleteCascade Resultset can in any one of the multiple resultsets generated for the same table because of multiple foreign key relationship to the same table. At the bind time , dependents are binded only once per table. We can not depend on mainNodeTable Flag to fire actions on dependents, it should be done based on whether the resultset has dependent resultsets or not.
