I recently had to rewrite several of the color-related widgets in order to make them behave better in the collaborative world. As part of that rewrite, SimpleColorMapWidget and the widgets derived from it (ColorMapWidget and LabeledColorWidget), while they behave the same, no longer use a ColorWidget internally. Therefore, the getColorWidget() method has been removed from these classes. I *hate* to remove methods, but in this case I didn't really have a choice. I couldn't think of any way to return something sensible, and returning 'null' meant that programs would compile and run until they ran into code that called getColorWidget(), at which point they'd most likely get an unexpected NullPointerException. I therefore chose to remove the methods, hoping that a compile error would make it obvious that a code change was necessary. Feel free to mail me any questions you might have about this or about workarounds for problems this might have created in your code.
