I'm starting to use cftry/cfthrow/cfcatch and am finding that custom types
aren't being caught. Am I doing this right?
<cftry>
<cfset avg_sales = getAverageSales()>
<cfcatch type="my.custom.exception">No average value was
returned</cfcatch>
</cftry>
<cffunction name="getAverageSales" returntype="numeric" output="false">
<cfquery name="q" ...>
select avg(some_col) as average_sales
from table
where ...
</cfquery>
<cfif not q.recordCount>
<cfthrow type="my.custom.exception" message="no data to
average" detail="...">
</cfif>
<cfreturn q.average_sales>
</cffunction>
The page is displaying "The value returned from function getAverageDailySales()
is not of type numeric", which was what I was trying to trap with the cfthrow
and the custom type.
If I change the cfcatch to type="any", the exception is caught and the "No
average value..." message is output.
What gives?
Thanks
