Hi,
It sounds like someone is calling Prototype's $() function with an
empty string or an undefined parameter. Prototype doesn't do that on
its own (someone would have noticed), so you'll want to look at the
code making the call, probably in a debugger so you can look at the
call stack. Note that a large number of Prototype's API calls start
out (effetively) like this:
function doSomethingNifty(element) {
element = $(element);
...
}
So the culprit may be a couple of levels up the call stack, not just
one.
FWIW,
