I'm not Matt but I will explain if I can ..
A getter is just a method. so getSomeArray() can return anything, including
an array. This means you should be able to do:
<cfset myArray = object.getArray() />
<cfoutput>#myArray[1]#</cfoutput>
without any problem.
Having said that, you may be looking for a collection object instead.
Collections have an item(index) method which will let you specify a specific
index and retrieve only that member of the collection. In CF, the best way
to implement collections are with an array, but you don't have to worry
about that as a consumer of the collection.
I have some generic collection code I wrote that I can paste you if you
like. In the meantime here is a sample component that does nothing special
but may help you understand what I am talking about:
<cfcomponent displayname="arraytest">
<cfset variables.instance = StructNew() />
<cfset variables.instance.theArray = ArrayNew(1) />
<cffunction name="init" access="public" returntype="arraytest">
<cfreturn this />
</cffunction>
<cffunction name="dumpSnapShot" access="public" returntype="void">
<cfdump var="#variables.instance#" />
</cffunction>
<cffunction name="setArray" access="public" returntype="void">
<cfargument name="theArray" type="array" required="yes">
<cfset variables.instance.theArray = Duplicate(theArray) />
</cffunction>
<cffunction name="getArray" access="public" returntype="array">
<cfreturn Duplicate(variables.instance.theArray) />
</cffunction>
</cfcomponent>
Thanks,
Eric

Subject: CFC Bean Getter
Calling Matt Woodward...
If a getter() returns an array, how do you access a position in that array
in the same line of execution?
<cfreturn getSomeArray()/> and I want to return the 1st cell only.
Am I breaking bean rules? Can a getter not return an array?
Thanks!
