I can't seem to reproduce this in a simple example. But in one of our applications, I see an endless series of calls to the ComponentListener that is added in PSwing's constructor. The calls alternate between componentShown and componentHidden. And there is nothing in the application code that appears to be triggering this, it keeps feeding back through PSwing.setVisible.
So rather than continue to chase my tail on this, I'd like to discuss the motivation for adding this ComponentListener. What purpose is it serving? It seems unnecessary. And undesirable - should client code be able to call setVisible on a Component? And both this ComponentListener and the override of PSwing.setVisibile seem a little dangerous, given how the entire Swing approach works by parenting JComponents to PSwingCanvas.ChildWrapper. Also note that an additional ComponentListener is added in PSwing.initializeComponent, could this be creating problems, depending on the call order? It seems like there is component initialization going on in the constructor that should really be in initializeComponent. Thoughts anyone?...
