[kepler-dev] Re: WindowProperties problem on Mac & freezing on Windows

[Christopher Brooks]

I'm running 1.4.2_05 under Windows and I have not seen this, but that
is no surprise

I'm not sure about the type conflict.

About the hang:
Under Windows, when a Java process hangs, typing Control-Break
will print a stack trace. (Unix users, try kill -3 on the PID)
I'm not sure what the corresponding stack trace generation command is
on the Mac.

My guess is that the deadlock is occuring because something is
invoking a Swing method outside of the AWT event thread.

    Hi All,
    
    
    Running a workflow on Mac OS X 10.3.5 with Java 1.4.2_05, I sometimes  
    get the following error:
    
    ptolemy.actor.TypeConflictException: Type conflicts occurred in .PIW on  
    the following inequalities:
       (TypeConstant, {bounds = {int}, maximized = boolean}) <=  
    (ptolemy.actor.gui.WindowPropertiesAttribute {.PIW._windowProperties}  
    {bounds = {21, 47, 1912, 645}, maximized = false}, {bounds = {int},  
    maximized = boolean})
    
    	at  
    ptolemy.actor.TypedCompositeActor.resolveTypes(TypedCompositeActor.java: 
    293)
    	at ptolemy.actor.Manager.resolveTypes(Manager.java:801)
    	at ptolemy.actor.Manager.preinitializeAndResolveTypes(Manager.java:710)
    	at ptolemy.actor.Manager.initialize(Manager.java:439)
    	at ptolemy.actor.Manager.execute(Manager.java:289)
    	at ptolemy.actor.Manager.run(Manager.java:852)
    	at ptolemy.actor.Manager$2.run(Manager.java:901)
    
    
    It's not always reproducible.  It happened to me twice today.  If I  
    click it away and try running it again, the problem disappears.  Has  
    anyone else seen this problem or know how to fix it?
    
    
    On a completely different note, sometimes when I run this same workflow  
    on Windows with Java 1.4.2_05, using View -> Run Window, the workflow  
    finishes but seems to freeze at the end.  The windows stop redrawing  
    themselves and I must forcefully kill Java to get the workflow back.   
    This seems to happen when I use the run window.  If I just click the  
    red triangle to run the workflow, it doesn't freeze.  Does anyone have  
    an idea what might cause this?
    
    
    
    Thanks,
    Xiaowen
