NullPointerException was thrown when setting property of JPanel. I created JFrame and add JSplitPane to it, and then I added JPanel to each pane. After that I wanted to set background of those JPanels but exc was thrown. Propery sheet showed the correct color, but form couldn't be excuted - the same exception was thrown.
Created attachment 12201 [details] exc stack trace
I'm running JDK 1.5.0 b28. I also forgot to mention that form couldn't be saved.
