Here is the code that may hurt your head:

[sourcecode lang="cf"]
<cffunction name="if">
	<cfargument name="val1" />
	<cfargument name="val2" />
	<cfif val1 eq val2>
		<cfreturn true />
	</cfif>
	<cfreturn false />
</cffunction>
<cffunction name="hello">
	<cfset var var = 2 />
	<cfreturn var />
</cffunction>
<cfif if( hello(), 2 )>
	LOL
</cfif>
[/sourcecode]

How cool is that ;)

I’m sending nested CFCs through the remote object back to Flex so ColdFusion has to serialize them to the form that may be understood by Flex. But I’ve got an error, somewhere I have an empty string where number is expected. You would expect that CF is smart enough to tell you what the problem is? Nope, it says:

Unable to invoke CFC - The value '' cannot be converted to a number.

Helpful, heh?

Why, WHY! it does not say what property is causing the problem? Surely it knows, it just keeps it for itself. Adobe – please fix!
