[kepler-users] loops in loops

[Christopher Brooks]

Hi Kianwee,
Problem 1 has to do with multirate systems.
The attached model has a top level that fires once and an inside opaque 
composite that fires 10 times.
I use a sequence to array actor to cause the inside opaque composite to 
fire 10 times.
See *http://ptolemy*.eecs.berkeley.edu/~eal/ee225a/lab/*sdf*.pdf

About problem #2, the Repeat actor repeats the input, it does not cause 
the upstream actors to be fired.

BTW - test cases would help here.

Also, take a look at some of the example models in the Ptolemy II 
distribution.
In the Kepler source distribution look for models in
ptolemy/src/ptolemy/domains/sdf/kernel/test/auto/
