CreateObject / var Incompatibility

[Darryl A. J. Staflund]

Hi all,

I am developing some CFCs at the moment and have found that if I try to invoke
a CFC using the following syntax from within a UDF:

<cffunction name="etc">
<cfset var obj = CreateObject ("Component", "componentName") />
</cffunction>

I get a 'Missing Argument Name' when executing the function. In order to
address this issue, I have to create the var and CreateObject apart as follows:

<cffunction name="etc">
<cfset var obj = "" />
<cfset obj = CreateObject ("Component", "componentName") />
</cffunction>

Is there something I am doing wrong with my code, or is this behaviour by
design? I am guessing that the 'var' somehow masks the name of the object from
the CreateObject function thereby causing the exception, but I am not sure why
this would be a problem.

Thanks,
Darryl

Yeah you can only get away with setting simple values when var(ing) a function
only variables:-

ie var myString ="";
var myBoolean = False;
var mySturcture = StructNew();

It is important to var all your function only variables as this will save you
many hours of head scratching with funny errors when it gets complex.

i don't believe that's true (at least w/cf7). i create complex java objects
quite often using vars and i just tested this w/a CFC & it worked as expected.
perhaps it's something else?



<cffunction name="aUDF">
<cfset var z=createObject("component","cfc.i18ncurrency")>
<cfreturn z.getCurrencySymbol("th_TH")>
</cffunction>
