I was working with an application now, and I noticed that it is doing tests:
<cfif query.column> --- do something </cfif>
If the query is empty (no rows), then this fails on OpenBD - I assume it returns false on ACF. Is this known/documented? Is this a compability issue to fix?

I agree, and I have already modified the code, but is this a compability issue? The application that I loaded off riaforge (tested on ACF) didn't work out of the box!
