Hi All,

     I would like to add a new attribute to the relation at the creating 
time by making subclass to TypedCompositeActor.java.
     I have made the following changes to the original ptolemy 
TypedCompositeActor.java for the function newRelation,

StringParameter param = new StringParameter(relation, name);


  /** Create a new TypedIORelation with the specified name, add it
   *  to the relation list, and return it. Derived classes can override
   *  this to create domain-specific subclasses of TypedIORelation.
   *  This method is write-synchronized on the workspace.
   *  @param name The name for the new TypedIORelation.
   *  @return A new TypedIORelation.
   *  @exception NameDuplicationException If name collides with a name
   *   already on the container's contents list.
  public ComponentRelation newRelation(String name)
          throws NameDuplicationException {
      try {

          TypedIORelation relation = new TypedIORelation(this, name);

StringParameter param = new StringParameter(relation, name);
                    return relation;
      } catch (IllegalActionException ex) {
          // This exception should not occur, so we throw a runtime
          // exception.
          throw new InternalErrorException(this, ex, null);
      } finally {

I am able to see the listed property to the relation, I am here with 
attaching the snapshot .
Now, I make same changes to the subclass JTypedCompositActor.java and 
modified the configuration file read
my subclass instead of ptolemy's original TypedCompositeActor.java. 
(with out any modifications to TypedCompositeActor.java file)

The changes I made to the configuration file 
basicKeplerActorLibrary.xml  is as follows

     <entity name="Composite Actor" class="griddles.JTypedCompositeActor">
      <property name="entityId" 

I am not able to see any property created for the relation. I am here 
with enclosing all the necessary file for you to look at it.

with regards,

Jagan Kommineni
