Re: Actor attributeChanged() methods and validating mutliple changes.
To make matters worse, the output ports available depend on the contents of this metadata. So the only way for the user to construct the workflow would be to configure, run wait for failure, then construct the relationships and run again. If I write my own parameter dialog pane would I have notification of commit? Kevin Edward A.

Re: Actor attributeChanged() methods and validating mutliple changes.
My suggestion doesn't require any work at all in the actor...
Certainly I would not override NamedObject.executeChangeRequests().
It's just a change in when the edit parameters dialog issues the
change request.

Then would I also override NamedObject.executeChangeRequests() or
would I have to have the actor implement ChangeListener then
register this as a change listener on this?
class MyActor extends Source implements ChangeListener {
public MyActor( CompositeEntity container, String name ) {
super(container, name);
addChangeListener(this);
}
public void changeExecuted( ChangeRequest change ) {
// Do extra validation d/l, etc.
}
public void changeFailed( ChangeRequest change ) {
// nothing?
return;
}
}
I think I saw the NamedObj uses a list of WeakReferences for the
listeners so I don't have to unregister in a finalizer, right?
How would this work when reading in a moml which contains one of
these actors already configured? Would it still get only one change
request, or would it receive multiples?

As I recall, the current dialog pane issues the change request for
a parameter
change when the parameter's editing widget loses the focus. I believe the
reason for this was that there was because there are several ways that a
dialog might get closed, and Swing is not rigorous about notifications
(or, perhaps more likely, I found the documentation incomprehensible and
couldn't get it to work).
I'm open to a change in the dialog box that would issue the change
request only when an Apply or OK button is pressed... This would probably
solve the problem...

You could check the parameters in preinitialize().

OSX Installation
I'm trying to install Ptolemy 5.0.1 on Mac OSX (10.3.9). I used the ZeroG installer, which seems to have gone very smoothly. My java version is java -version java version 1.4.2_09 Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_09-233) Java HotSpot(TM) Client VM (build 1.4.2-56, mixed mode) Any attempts to run anything in the installed directory fail. Originally, I was getting some cryptic messages about LAX and Java versions. I edited vergil-full.app/Contents/Info.plist and changed the JVMVersion key to 1.4*. Note that to see all of this I have to run vergil-full.app/Contents/MacOS/vergil-full directly from the terminal. Otherwise the application tries to start up and then mysteriously exits. After making the above-described change, here's what I get: $ vergil-full.app/Contents/MacOS/vergil-full Invocation of this Java Application has caused an InvocationTargetException. This application will now exit. (LAX) Stack Trace: java.lang.NoClassDefFoundError: ptolemy/vergil/VergilApplication at ptolemy.actor.gui.jnlp.MenuApplication.main(MenuApplication.java:119) at ptolemy.actor.gui.jnlp.FullApplication.main(FullApplication.java:64) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:324) at com.zerog.lax.LAX.launch(DashoA8113) at com.zerog.lax.LAX.main(DashoA8113) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:324) at apple.launcher.LaunchRunner.run(LaunchRunner.java:88) at apple.launcher.LaunchRunner.callMain(LaunchRunner.java:50) at apple.launcher.JavaApplicationLauncher.launch(JavaApplicationLauncher.java:52) Segmentation fault Does anyone have any ideas what might be the problem? Did I miss something? It looks like the installer left me as the owner of everything, though there could be individual permission problems in any of the many files. I'm not sure where to go from here. Thanks, -Joe Porter
