Re: js error - document has has no properties

This thread got me thinking (very scary, that) and I'm curious as to what
techniques are popular for resolving a similar issue - dependancy hide/when
values. For instance, if I have a field that is hidden based on the value of
another field (which, for me at least tends to be a keyword type field) or
simply hidden if another field is blank, the form must be refreshed in the
browser window for the new field to show up. Are there other techniques that
can avoid having to refresh on keyword change or use a hotspot to refresh the
form which would make the new fields visible? I hope all that made sense.
