well i tried this out, and all it proved is that getElement returns a
random ordered list. :(
i wanted to do this feature independent of the form itself, but as
most of my forms are generated dynamically, i will simply generate a
tabIndex attribute on each element. In the future i would like to
implement an "xforms repeat"-like functionality, and then i will have
to be aware of the maxcount of each repeat but that's not so hard i
think.
so thanks for all the replies. :)
