[kepler-users] Sequence to Array problem

[Christopher Brooks]

Hi Tomasz,
The problem is that in sta-1.xml, after running with
an array of three elements, and then changing the Const
to an array of two elements, the SequenceToArray actor
is not being enabled.

The issue seems to be with the arrayLength PortParameter
of SequenceToArray.

If I animate execution, then I can see that the ArrayToSequence
is firing before the ArrayLength actor.  It appears that
the SequenceToArray actor is not being enabled after the arrayLength
gets updated.

I tried to create a regular model that illustrated this bug
by using a Sequence actor instead of a Const but could not replicate
the bug.

However, I was able to create a Tcl test that reads in the model, runs
it, checks the output, changes the Const and then runs the model again.

I've included the Ptolemy model that is used in the test.  Note that
the model writes to stdout for testing purposes.

I'll see if I can take a look at this with Edward.

_Christopher
