Since the getItemAt() method of ArrayCollection returns an Object, splitting the code to store this result in a var of type Object should have made no difference. I suspect that something else is going on that you're not telling us about.
Are you getting a compile time error or a runtime error? Exactly what does it say? Also... There is no reason to make objUser an instance variable rather than a local variable. And the acUser parameter of the blah() method isn't being used in the method body that you showed.

This was incredibly frustrating but after playing around (and rebooting my computer numerous times from the debugger crashing) I finally figured out how to reference the data in the arraycollection. I didn't have to typecast it. However, I had to process it one function at a time. I tried strEMail = String(GlobalVars.instance.acUser.getItemAt(0).strEMail); and that didn't work; it kept throwing an error that it didn't know about strEMail. After playing around I discovered that if I broke out the functions it would work. This is what worked for me: private var objUser:Object; private function blah( acUser:arrayCollection): void { objUser = GlobalVars.instance.acUser.getItemAt(0); strEMail = String(objUser.strEMail); } After I got the results I wanted, I tried it again as one line and Flex threw an error that it again didn't know about strEMail. Perhaps that's a bug...? -sj ________________________________ From: flexcoders@yahoogroups.com [mailto:[EMAIL PROTECTED] On Behalf Of Scott Sent: Friday, July 18, 2008 8:12 AM To: flexcoders@yahoogroups.com Subject: {Disarmed} Re: [flexcoders] Variable Typecasting It seemed to have taken that but now it's still not pulling the data in as I would expect it. The getItemAt(x) in reading looks like it would pull in the whole record at 'x'. However, it won't let me refer to the record as getItemAt(0).strEMail since it doesn't know strEMail exists in that collection. In structures (in C++/Coldfusion/etc...) I had to define the variable names within the structure. However, in AS3 I just defined the variable: [Bindable] public var acUser:ArrayCollection = new ArrayCollection(); How do I access the strEMail from the array collection (or at least tell the Flex compiler that the variable really does exist).

I know that's the way I do it to cast MovieClip names.

Here's the code: public var strEMail:String; ... Private function ... { strEMail = GlobalVars.instance.acUser.getItemAt(0); } That above line of course throws an error because it's not sure that the variable at (0) is actually a string even though I know it is. In C++ I would just tell it using a typecast that it is a string. How can I copy that element into a variable?
