[kepler-dev] NIL token

[Jing Tao]

hi, Christopher:

According to the changes you made in ptolemy about nil token, I made the 
changes in kepler for missing value too.

Since currently we only have one public static variable NIL in Token class 
(NIL is a generic type and there is no any other nil in sub token 
classes), I think every missing value element should be replaced by the 
NIL token no matter what the data type it is. But when I run the workflow 
test, I got some error:

Workflow workflows/test/test-ecogrid-eml-gce-data.xml FAILED:
[java] ptolemy.kernel.util.IllegalActionException: Run-time type checking 
failed. Token nil with type general is
incompatible with port type: int

So it seems the NIL token is not compatible to int port type. Did I miss 
something? How can I make the NIL token to compatible int port type?

Thanks,

Jing
