I just recently ditched cfinvoke for something similar to this:
<cfset var metadata = getTransfer().getTransferMetaData
(getClassName()) />
<cfset var keys = ''/>
<cfset var key = ''/>
<cfset var method = ''/>
<cfset var value = ''/>
<cfset keys = StructKeyList(arguments)/>
<cfloop list="#keys#" index="key">
<cfif StructKeyExists(variables,'set#key#')>
<cfset method = variables['set#key#']/>
<cfset value = arguments[key]>
<cfset method(value)/>
</cfif>
</cfloop>
so instead of using this I use the variables scope and instead of
using cfinvoke I just call the function directly.
It seems to perform better but I'm not 100% sure it's thread safe
yet...
