[kepler-users] Optional Parameter

[Edward A. Lee]

There is no way that I know of to do this easily...

A couple of notes:

The parameter names should match the field names.
Otherwise, you will have problems if you use the actor
in actor-oriented classes. If you want the user to see
a different name, I suggest:

enableOperation = new Parameter(this, "enableOperation");
enableOperation.setDisplayName("enableCatalogUpdate");
