of it's attributes when initially encountered, and then uses those values.
So if the length of the 'iterations' array changes, CFLOOP doesn't know that
it has a new stopping point. CFSCRIPT's for loop, on the other hand,
definitely reevaluates the arrayLen(iterations) _expression_ every time
through the loop.
If my suspicions about CFLOOP are correct, then those two code blocks are
NOT equivalent, but these blocks are:
<cfscript>
count = arrayLen(iterations);
for(i=1;i LTE count; i = i + 1)
{
thisIteration = getIteration(iterations[i]);
if(this.error)return thisRoute;
arrayAppend(thisRoute.iterations, thisIteration);
}
</cfscript>
<cfset count = arrayLen(iterations) />
<cfloop from="1" to="#count#" index="i">
<cfset thisIteration = getIteration(iterations[i])>
<cfif this.error><cfreturn thisRoute></cfif>
<cfset arrayAppend(thisRoute.iterations, thisIteration)>
</cfloop>
