I'm using jQuery Validate and would like to re-validate a group of fields whenever one of them is changed (or possibly, whenever one of them validates successfully). My attempts so far just create infinite loops.

Is this possible, or does the plugin design preclude it?

(Specifically, I've got a method that requires at least X of group Y to be filled out, and as soon as that's true, I'd like all those fields to re-validate. Currently I'm clearing out their error messages with my own code, but that's a hack - it also hides unrelated validation problems until the form is re-submitted.)
