tracker issue : CF-3039641

Problem:

There is currently no way of dynamically invoking a CFC's method in CFScript.In tags, you are able to use <cfinvoke> to provide this functionality, but if you are in a Script based cfc this is not available.Railo provides a nice way of doing this, in the form of:foo = new Foo();foo[methodName]();Which I think would be a really nice addition to the ColdFusion language, but I would also be happy with a 'invoke' cfscript syntax as well.One thing to note - currently you can pass in the numerically keys arguments into <cfinvoke> as an argumentCollection and it works perfectly.  Please ensure that this continues to work in CFScript, and therefore, this would work in the same way it would for <cfinvoke>args = {1="foo", 2="bar"};foo = new Foo();foo["myMethod"](argumentCollection=args);This is very important for usage with onMissingMethod.

-- Added as per discussion with Adam Cameron/Ray Camden --
The following syntax does seem to work but does not work correctly.
 bar  = foo[method];
 bar();

This happens because the method execution holds the wrong context while executing. The issue is clearly demonstrated by the following example and it needs to be fixed.
C.cfc

{code:java}
component {

    variables.where = "In the CFC!";
    
    public function whereAmI(){
        writeOutput(variables.where & "<br />");
        hidden();
    }
    
    private function hidden(){
        return;    
    }
    
} 
{code}



test.cfm

{code:java}
<cfflush interval="1">
<cfscript>
    variables.where = "In the calling code!";
    
    o = new C();
    
    o.WhereAmI();
    
    methodName = "whereAmI";
    
    methodToCall = o[methodName];
    
    methodToCall();
</cfscript>
{code}
