The problem is inside your init() method. You're not returning the object in
the cfreturn.
<CFFUNCTION name="Init" access="public" returntype="CachedQuery"
output="false">
<CFARGUMENT name="DSN" type="String" required="yes">
<!--- Set the DSN to the local variables for the CFC --->
<CFSET Variables.DSN=Arguments.DSN>
<!--- Return the query object --->
<CFRETURN This>
</CFFUNCTION>
This is the init method of my cachedquery CFC. Note that I'm setting a
returntype equal to the name of the CFC, but the entire returntype is not
needed. The main point is that I'm returning THIS which means I'm returning
the object back to the call to be stored in the external variable.
Using this call:
<CFSET Application.CachedQuery=CreateObject('Component',
'Components.CachedQuery').Init(DSN)>
will call the cachedquery CFC, call the init method, pass it the DSN and
when the method is done, it'll pass the entire CFC back as the value to be
assigned to the Application.CachedQuery variable.
