CF 7.0 ArraySort Problem

[sfdower]

I have an array containing strings like:
G_CC
G_ABC
ADMIN_DEBUG

Under CF 5 & 6.1 the following works fine:

<cfset rtvl = arraysort(grouparray,"text")>

Under CF 7.0 I'm getting:

The error occurred in D:\IBMautodev\WebProfiles\main.cfm: line 44

42 : <cfabort>
43 : --->
44 : <cfset rtvl = arraysort(grouparray,"text")>
45 : <cfloop index="i" from="1" to="#iNumGroups#">
46 : <cfif grouparray is not "">

Any suggestions????

Thanks,
Steve
