Hi Chong,
I'd ckeck for null by using IsDefined and dot notation. While the key
may exist, the value could be null.
Something like;
<cfif IsDefined('myStruct') and IsDefined('myStruct.myKey')>
<cfset myValue = myStruct[myKey]>
</cfif>
Or cfscript eqivalent ;)
Seems like overkill, but it might help reveal what's missing.
