Argumentcollection for UDFs/CFCs works like attributeCollection for
custom tags. Basically...
<cfset a = structNew()>
<cfset a.mode = foo>
<cfset z =
someCFC.methodName(argumentCollection=a)>

How do i
use argumentCollection? is there some kinda collection available in CFMX like
Java Collections?
Thanks,
Joe
If you
want to pass the argument names dynamically, I suggest you use the
argumentCollection
Thanks Nathan, I knew.. there was a way around the
"evaluate"....
It was
really bothering me.. to advocate NOT to use "evaluate"
and
having
forced to use it.
One more
question.. havent tested it..
Can i pass
the parameters in
value=
variables[objName].dynMethod(request.param1,request.param2);
Thanks

A
similar method, if you need the dynamically called method to have access
to the CFC internals might be:
<cfscript>
object = createObject("component",
"yourComp");
objName =
"object";
methodName =
"yourMethod";
variables[objName].dynMethod =
variables[objName][methodName];
value=
variables[objName].dynMethod();
writeOutput(value);
</cfscript>
In
the original, you are "stripping" the method off the CFC
instance and making it local. In my method you are "tacking"
the dynamic method back onto the CFC instance. It only matters if
the method you call also calls private/public methods of the CFC and/or
uses instance data of the CFC.
This works (tested):
<cfscript>
object =
createObject("component", "yourComp");
objName =
"object";
methodName =
"yourMethod";
dynMethod =
variables[objName][methodName];
value=
dynMethod();
writeOutput(value);
</cfscript>
Is that what you're after?

Thanks Samuel... but that does NOT
work.
The only way i can get it to work is using an
evaluate.... and i really dont want to use "evaluate"
variables.execMethod="request."&variables.varClass&"."&variables.varMethod;
'#variables.varName#'=
evaluate(variables.execMethod);
Your Code...
variables[varName] =
request[variables.varClass][variables.varMethod](); // Complains
about "()"
The compiler complains about the "()" at the
end... can u get it to work?
Thanks

Subject: RE: [CFCDev] Dynamic
CFC Calls
two
ways,
1.
request.dataObj =
createObject("Component","Website/MyData");
varObj="dataObj";
varMethod="getStateData"; // removed the
parens
varName="someData";
variables[varName] =
request[varObj][varMethod]();
2.
<cfinvoke component="#request[varobj]#"
method="#varMethod#"
returnVariable="#varName#">
Untested but both should work.
hth,
Sam
Anybody know how to dynamically call methods
in CFC's
<cfscript>
request.dataObj =
createObject("Component","Website/MyData");
varObj="dataObj";
varMethod="getStateData()";
varName="someData";
// Now, i want to be able to call the CFC
Dynamically, something like
'#varName#'=request["#varObj#"]["#varMethod#"];
//.#varMethod# doesnt work
either.
</cfscript>
I am getting the below from the above
code.
"Element getleftNavLinks is undefined in a
Java object of type class coldfusion.runtime.TemplateProxy
referenced as"
What am i missing?..
Thanks
Joe
