Right you
I had the same problem. It appears that even though CF

Yes, all java vars need to be typed, but it seems strange that CF seems
to think that the string is a date, tries converting
does CFMX create java files
The original MX did, but 6.1 doesn't - the compiler does a direct CF

huge difference in production but sure makes development
Can someone else try running this little bit of code please:

cfdump var=#variables.newQ#
cfquery name=variables.testQoQ dbtype=query

If so, you cal use an evaluate within the loop:
Or you can do it without using evaluate() by using summat like:
Replace this:
evaluate('dropship'indexvalue'_value')
With this:
variables['dropship'indexvalue'_value']
That assumes that the vars are in the variables scope - if they're
coming
I must be missing something, then. As far as I can tell, the

Something like this?

Try using getMetricData() from your code.This provides the
