Method PurchReqLineDS

public display container workflowIcon(PurchReqLine _line)

        {

            workflowIconObservableLink.observe();

            if (Workflow::findWorkItemsForCurrentUser(_line).elements())

                imgRef = ImageReference::constructForSymbol(ImageReferenceSymbol::Workflow);

            }

            else

            {

                imgRef = ImageReference::constructForSymbol('');
