And on another note, if you use type="ANY" instead of "ALL", it will work ;o) Sorry,
I couldn't resist.
I love error handling in CF, especially in 4.5+, since it's very advanced for a "tag
based language". One of the places it's really helped
is this drug testing application I've done. When raw test files come from the lab,
some may be corrupt, or some may have invalid values, especially for dates (imagine
that...). CFTRY/CFCATCH has been a godsend in that I loop through all of my tests and
catch all types of errors, whether they stem from an incomplete file or a wrong
date,identification number, etc. I can then process each file differently and send it
to the appropriate person for dissemination and trouble-shooting... Most of the time,
however, that person is me... :o|
