AssertValueRequiredAspect

Checks whether a given property has a non-null value.

Examples

The following example makes sure that the contract start date is specified for any new worker. The pointcuts define when the value assertion must happen.

<AssertValueRequiredAspect Identifier="Directory_UserRecord_ValueRequired_ContractStartDate" ExpressionBinding="Workflow_Directory_User:Directory_User.Records" Binding="Workflow_Directory_User:Directory_User.Records.ContractStartDate" Message_L1="The contract start date is required">
    <PointCut Activity="Directory_User_NewInternal:Request" ActivityState="ActionWithRefine-Executed" />    <PointCut Activity="Directory_User_NewInternal:Review" ActivityState="ReviewWithFeedback-Approved" TemplateTransformation="NewInternalWorkflowIsReviewRequired" />    <PointCut Activity="Directory_User_NewExternal:Request" ActivityState="ActionWithRefine-Executed" />    <PointCut Activity="Directory_User_NewExternal:Review" ActivityState="ReviewWithFeedback-Approved" TemplateTransformation="NewExternalWorkflowIsReviewRequired" />  </AssertValueRequiredAspect>
