Why did you want to do this in a el function? Why not a action method?
Can you describe your usecase?

2007/1/23, lightbulb432 <[EMAIL PROTECTED]>:
Now where would I use that function? I created a function and tried using it
as the value of h:commandButton's action attribute (because I want it to be
executed when that form is submitted), but I receive an error:
Not a Valid Method Expression: #{prefix:add(collection,value)}
