Ricardo,
Let me give this a try. It'll have to be done in a couple of seperate
steps.
<cfscript>
if (isDefined("newWiz.deadlines") and isArray(newWiz.deadlines)) {
// here's the tricky part. CF doesn't force the programmer to insert
// elements into any order. So, that's on you.
if ( ArrayLen(newWiz.deadlines)) {
/*
all your code that depends upon elements of the array go here
*/
}
}
</cfscript>
Obviously some tweaking will have to be done in order to fit your
circumstance, but something like this should fit your needs.
