Just
wondering, havent seen any docs on this.
Are
there any problems setting/manipulating scope variables like
1.
Server Scope
2.
Application Scope
3.
Request Scope
4.
Client Scope
Variables within CFC's.. Appreciate any input.
Thanks,

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
Joe Eugene
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

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
