I have been working with the MooTools framework for the past week or so.  I am realyl starting to like not having to code everything by hand and am thinking it might save quite a bit of labor in the near future.  A tool that extends the MooTools 1.2.1 framework is FormCheck.  It makes client side validation of forms an absolute snap.

While everything worked great in IE 7, I was having serious issues getting the FormCheck code to fire when working in FireFox 3.  After lots of testing and beating my head against the keyboard, I figured out that the problem was caused by Domino not generating an ID attribute for the FORM tag.  I was able to finally work around it by setting the ID to be the same value as NAME before trying to validate the form. 

To me, this is an extra step that shouldn't have to be done by deverlopers.  I have created an ideaJam entry to have the Domino server do this automatically.
