i am consuming one API and the resopnse is weird i am getting undefined in the struct struct actualRunway : undefined i am looping over a struct and if i add a check using isDefined, it says syntactically invalid call to isDefined,. if i compare the value to undefined, i am still getting an error

<cfloop collection="#arrival#" item="idx">
<cfif isDefined('arrival[idx]') and arrival[idx] neq 'undefined'>

What do you think "syntactically invalid" might mean in this context? Did you look @ the docs for

isDefined

to see if it cast any light on that error message?

@gsr, did you fix your issue? The problem might be because you need to use

StructKeyExists()

instead of

isDefined()

for an evaluation of

arrival[idx]
