The "class action" menu items used to work in Kepler.
I'll add them back.
However, can actor classes defined in one workflow be
instantiated in another?
Ian, you could try the ModelReference and VisualModelReference
actors, which execute a workflow defined in a file.

I was referring to composite actors that are themselves
class definitions. It appears that Kepler does not expose
this capability in the GUI (the commands aren't there to
convert a composite actor to a class nor to instantiate
classes). So what you have in your example is a _copy_
of the composite actor. Hence, updates to the original
have no effect on the copy.
The mechanism I'm referring to is that a composite actor
may define a _class_, and you can then have multiple
instances of the class. You can also have subclasses
that override certain aspects.
If someone is interested in making this capability available
in Kepler, it would be great. I think it's mostly a matter of
adding it to the menu commands.
There is a paper on this mechanism here:
http://ptolemy.eecs.berkeley.edu/publications/papers/07/classesandInheritance/index.htm
There are demos in the Ptolemy tree here:

I am also interested to know the details behind this problem. What
Edward referred as base classes and sub classes apply only to Java
codes, where you have to write and compile an actor in Java. I believe
the type of “base” actor that you described is called a composite
actor/workflow.
Is it possible to share the same instance of a composite actor among
multiple workflows? I know that besides dragging an existing kar from
the panel as described by Ian, you can also use an actor called
CompositeActor. Are there any other methods to use a composite actor?

Hi Edward , thank you for the reply.
Where can I find the "Open Instance" option? Only "Open Actor" appears
in context or any other menu, see picture, if it is not scrubbed.
Example attached, details also written below.
I have tried a new scenario from scratch which results in the same
problem, Ie changes not propagating. It appears that actors are just
getting plain copied into workflows that use them.
Thank you for your attention,
Ian.
Steps to create problem:
-I made a simple work flow “A”, return a string
-Saved the .kar for A in the MyWorkflows directory, and closed Kepler
-Relaunched Kepler,
-Made a second work flow “B” dragging actor A from the components panel
-Ran B, verified expected result
-Saved B to desktop and closed Kepler.
-Relaunched Kepler
-Opened actor A and modified string
-Saved A, and closed Kepler
-Relaunched Kepler, opened B
-Ran B, received previous result – the first string and not the updated
string
-Opened the A actor located on the canvas of B – it had the previous
string
-Opened the file A in the MyWorkflows directory – it had the update
string.

Changes to base classes should propagate to instances or subclasses,
unless the instances or subclasses override the base classes somehow.
perhaps that is what is happening? If you select "Open instance" instead
of "Open actor" you can see what is an override vs. what is inherited
from the base class.
An example would help...
