Hi Andrew, Perhaps the remote service buffer needs to be a parameter? You can hide parameters from the user by setting it as an Expert parameter.
See $PTII/ptolemy/actor/lib/gui/SketchedSource.java: initialTrace.setVisibility(Settable.EXPERT); You could also try having your remote service buffer be an Attribute. I'm not sure if that will be preserved though. You might also need to get trigger change requests, though that should be happening for you. _Christopher -------- I'm working on an atomic actor right now where user-specified parameter changes trigger further updates to the actor. For example, the user enters the name of a file that contains a remote service definition, and the actor loads and processes the file, extracting from it information like port names and types. The user update (entering a file name) causes a cascade of calls to attributeChanged() -- the file is read into a buffer variable, triggering parsing of the buffer contents, triggering the creation of new ports and the assignment of types to those ports, and so on. The end result is a correctly-configured actor. It has the correct input and output ports, with the correct types; it knows how to bind to the remote service. However, when I save and reopen the model containing the actor, I find that a lot of the configuration values were not persisted. In particular, the port types and the contents of the service definition buffer don't survive the round trip. What objects do I need to notify when these "autonomous" updates occur so the new values make it into the exported MoML? Thanks, Andy Z. --- Andrew L.
