    Hi,

       I wrote a workflow which included a customized activity written with C#. When I click "Additional Criteria" button in Pick addtional criteria dialog as I wanted to modify trigger criteria, an error occured, said

    Unable to render the criteria. 
    
    '<Criteria xmlns=http://Microsoft.EnterpriseManagement.Core.Criteria/>
    
     <Expression>
    
      <UnaryExpression>
    
       <ValueExpression>
    
        <Property>$Context/Property[Type='384eebc6-0a62-9a9e-ddb4-09d1618d3d83']/b3cfd8c2-8e9a-fad8-49e3-d480bf3daab6$</Property>
    
       </ValueExpression>
    
      <Operator>isNotNull</Operator>
    
     </UnaryExpression>
    
     </Expression>
    
    </Criteria>' is not valid.
    
    


    What is wrong with it? Thanks!
