More of a note to myself to fix this. FileArrayEditor is listening on a JFileChooser (try the mount dialog) for changes. When you select a folder with the mouse, JFileChooser will fire two property changes - one from setSelectedFile and one from setSelectedFiles. FileArrayEditor should discriminate and not refire both these events - while it's trivial, it is causing PropertyPanel to try to write the value back to the property twice - if an error dialog needed to be shown, there would end up being two of them.
Passing property editor issues to new owner, Jirka
