getValidationScript in models - by: antonio.grr

Hi.
In some models getValidationScript call parent method but does not return anything:
Attachment ,BillLine, CheckListDefinitionLine,CheckListLine,Job,JobDefinition,Note
In some models getValidationScript is redundant (just returns parent method)
BudgetElement, CheckList,ComponentMain,OrganizationMain,ProductMain,ProductOrComponent,StatusMain,TenderStatus,TestCaseMain,VersionProject
in IndicatorDefinition is called twice
