Java Development Tools

Hi,
I have a read-only view object which is based on an SQL query. I have a transient attribute defined called 'Action'. I want to default it's value to the value 'Add' and then be able to manipulate it as required.

I have tried setting the default value in the VO definition and also added a view row implementation class and overidden the create method to set the default value.

None of the above have worked. The attribute is always null in the ADF read-only table and also null if I use row.getAttribute("Action");

Is there something else I need to set?

this is from the XML defintion of the VO:

  <ViewAttribute
      Name="Action"
      IsSelected="false"
      IsPersistent="false"
      DefaultValue="Add"
      Type="java.lang.String"
      ColumnType="VARCHAR2"
      AliasName="VIEW_ATTR"
      SQLType="VARCHAR" >
   </ViewAttribute>

regards,
Brenden
