Looks like receivers are not getting created for one of the actors, which
shouldn't happen.
It would be helpful to get the generated MoML file, along with any custom
java actors you
are using...

The expression language does not have any bindings for xml tokens,
unfortunately It probably should have at least a function that takes a
StringToken and returns an XMLToken.
There are several possible immediate solutions:

With hot-swap, the classes are expected to be consistent with one another

Since there is no way to ensure this, an exception will likely result.

To speed up type comparisons, the TypeLattice keeps a cache of comparison
information in a 2D array. The 2D array is preallocated in the TypeLattice

In all seriousness, the Icon Editor was written quite a while ago and was
never really useful enough to be used, even when it did run.

Yes, this is a bug in the code generator that shipped with the beta.
It is likely that the final release will include a fix that allows
constants (like PI) to be dealt with
correctly.
Note that for other reasons, the Butterfly demo will not generate usable

Assuming you are writing your own actor, the easiest way to deal with this
is to
use a StringAttribute instead of a Parameter.
This issue comes up in other contexts as well... for example, if you have

At the same time it was a base class for all the other token classes. We

You're right... You need a queue to keep the incoming requests and an
'arbiter' to dispatch requests when servers become idle.
I imagine it would be fairly easy to build an arbiter using an FSM
model. When a server finishes processing, it sends an event to the arbiter
saying it is available.
It is probably easiest to rely on matlab for more complex plots: contour
plots, surface plots, charts, etc...
Fortunately, it is relatively easy to get data into matlab using the matlab
interface in ptolemy...
At various times we've pondered improving this situation, but it can be
quite a bit
As you mention, time in Ptolemy models is in some sense a global variable..
Timed domains are (by default) built so that at all levels of the model
follow some basic consistency rules.
However, this it not, strictly necessary. Some domains, such as CT 'fudge'
