Being that CFAJAX is setup to have your CFC methods return strings.....
What we use is a cftry/cfcatch block (in the method you are calling) and in the
CFCATCH block we have wrapped CFSAVECONTENT around a CFDUMP of the CFCATCH
struct and return the resulting variable. This results in an HTML string being
returned containing a dump of the error details as reported by CFCATCH.
Like so:
<cfcatch type="any">
<cfsavecontent variable="theError">
<cfdump var="#cfcatch#">
</cfsavecontent>
<cfreturn theError>
</cfcatch>
