Arrays of Component Objects

Before I give detailed examples, can anyone provide any insight into tips or tricks on creating arrays of objects? I'm currently attempting to create these arrays and it is giving me a bit of a problem.

I am attempting to create a main User structure that holds multiple variables including an array of account objects. Each account object has parameters as well as an array of sub-objects.

I am able to create the first array of objects, but when I refer to a function within one of those objects to create a sub-object, my code yells at me.

I can provide details later, but looking for any inside tips or tricks I may be forgetting first.

Thanks

After looking at this a little longer, I realize this may not make any sense without an example. Here is the code pages that I have:

User.cfc

Code:

<cfcomponent displayname="User" hint="Defines a user" output="false">

	<cffunction name="Init" output="false" access="public">
		<cfargument name="username" type="string" required="false" default="myuser" />
		
		<cfset variables.username = Trim(arguments.username) />
		<cfset variables.accounts = ArrayNew(1) />
		
		<cfreturn this />
	</cffunction>
	
	<cffunction name="addAccount" output="false" access="public" returntype="void">
		<cfargument name="accountNumber" type="numeric" required="true" />
		
		<cfset variables.accounts[ArrayLen(variables.accounts)+1] = createObject("component","/LearningArea/smahony/ObjectTesting/account").init() />
		
		<cfset variables.accounts[ArrayLen(variables.accounts)].addAddress(1234567890) />
		
		<cfreturn />
	</cffunction>
	
</cfcomponent>

Account.cfc

Code:

<cfcomponent displayname="Account" output="false">
	
	<cffunction name="init" access="public" returntype="void">
		<cfargument name="accountNumber" type="numeric" required="false" default="0" />
				
		<cfset variables.accountNumber = arguments.accountNumber />
		<cfset variables.addresses = arrayNew(1) />
		
		<cfreturn />
	</cffunction>
	
	<cffunction name="addAddress" output="false" access="public" returntype="void">
		<cfargument name="premiseID" type="numeric" required="true" />
		
		<cfset variables.addresses[ArrayLen(variables.addresses)] = createObject("component","address").init() />
		
		<cfreturn />
	</cffunction>
	
</cfcomponent>

Address.cfc

Code:

<cfcomponent displayname="Address" output="false">

	<cffunction name="Init" output="false" access="public">
		<cfargument name="addressID" type="numeric" required="false" default="0" />
		
		<!--- Initialize all variables needed --->
		<cfset variables.addressID = arguments.addressID />
		
		<cfreturn this />
	</cffunction>

</cfcomponent>

What is the best way to do this? When I try to add a new address object right after creating the account object it yells saying element 1 cannot be found. I'm at a loss (or not understanding what I'm trying to do)
