I guess it doesn't. But I'm not sure what you mean by "supporting key -
keyref". There is no real-time validation for that, but the complete
validation should work. If you mean to restrict the values with a given
Swing component, I would suggest creating a plugin so that you can
control the GUI as you prefer. There is no generic Jaxe element so far for
this task.
