That's about it - typical things that happen are that query results or loop
iterators ('i') suddenly become invalid partway through a method.
This means you have to var *every* variable used in a CFC method - including
cfhttp results, loop indexes, query names etc.

Well most of us know why we should var the local variables inside a cfc
function, but my question was, are there tools that help you find unvared
variables?
I though I saw something somewhere at one point but can't seem to find it.

check for unvared variables in a cfc

RE: check for unvared variables in a cfc
If you have another variable with the same name as a CFC variable in the same scope, your CFC's variable values could 'bleed' into your other scope variable. If I understand it correctly, you only have to worry about it with variables in the 'variables' scope, or local variables in the CFC, not 'arguments' variables that are passed in to the CFC, or any other scope variable you might use (like application). I'm not exactly an expert, so someone will correct me if I'm wrong. -Original Message- From: Brad Wood [mailto:[EMAIL PROTECTED] Sent: Wednesday, August 09, 2006 4:11 PM Please pardon my ignorance about this, but could someone please explain exactly what you are avoiding by varing all our variables in a CFC.
