Description

I get an exception when switching from SDF to DDF inside a Case Refinement. It seems to be caused by having an unconnected input port.

To reproduce:

1. open $PTII/ptolemy/actor/lib/hoc/test/auto/Case1.xml
2. add a new input port to Case
3. run the model
4. open the Case actor and replace SDF in each Refinement with DDF
5. run the model

The error is:

java.lang.IllegalArgumentException: hasToken() requires a positive argument.

The current workaround is re-starting Kepler. The problem went away when I did it.
