Ya I do something similar.
All my cfc's extend a basic root CFC that contains a function that
generates a common return structure which has the following elements:
- Msg, a message for the user
- isError, a flag indicating if an error occured or not.
- returnStatus, a return code (eg OK, BADQUERY, etc...)
So in your cfc you do something like:
<cfset stResult = returnStruct()>
<cftry>
<cfquery ...> ... </cfquery>
<cfcatch type="any">
<cfset stResult.isError = "true">
<cfset stResult.returnStatus = "BADQUERY">
<cfset stResult.msg = CFCATCH.Detail>
</cfcatch>
</cftry>
....
....
<cfreturn stResult>
Then in Flex on any WS or RO call if an error occured you can alert the
user and do whatever you need to do.
