Is there a way to access an array as an array within an object once you stick it into a collection?

The function alen() fails when I use it on an array property within an object that is added to a collection object. The code below shows the scenario. The first messagebox shows that the type of aList is "C". When I try to access the aList of the object inside the collection, I get type "U". I must be missing something....

Thanks in advance...

mybox = CREATEOBJECT("obox")
myball1=CREATEOBJECT("oball", "1 inch", "blue/white", "hard")
mybox.addball(myball1)

DEFINE CLASS oball as Custom
	PROCEDURE init
		LPARAMETERS cSize, cColor, cHardness
		this.AddProperty('aList(1)')
		DIMENSION this.alist[3,2]
		this.alist[1,1] = "SIZE"
		this.alist[1,2] = cSize
		this.alist[2,1] = "COLOR"
		this.alist[2,2] = cColor
		this.alist[3,1] = "HARDNESS"						
		this.alist[3,2] = cHardness
	ENDPROC 
	
ENDDEFINE 

DEFINE CLASS obox as Collection 
	PROCEDURE addball
		LPARAMETERS toIn
		MESSAGEBOX(TYPE("toIn.alist",1))
		this.Add(toIn)
		MESSAGEBOX(TYPE("mybox(1).alist",1))
	ENDPROC
