There's nothing inherently wrong with the code above - some more context 
would help the diagnosis (where exactly does the problem come in, what does 
it look like, etc.).
	I have tried out the following code and it works just fine, displaying a 
window with a blue 'X' in the middle of it:

;;;;;;;;;;;;;;;;
(create-instance 'win inter:interactor-window)
(create-instance 'agg opal:aggregate)
(s-value win :aggregate agg)

(setf a 'abc)
(setf b 'efg)
(create-instance a opal:line
		 (:x1 130)
		 (:y1 90)
		 (:x2 230)
		 (:y2 190)
		 (:line-style opal:blue-line))
(create-instance b opal:line
		 (:x1 130)
		 (:y1 190)
		 (:x2 230)
		 (:y2 90)
		 (:line-style opal:blue-line))
(opal:add-components agg (eval a) (eval b))
(opal:update win)
;;;;;;;;;;;;;;;

Is that what you want?
