I need my Method to return a 2 dimensions array As String.
I try to set the return type as String(,) as mentionned in the documentation
[quote]… If you need to return a multi-dimensional array, place one fewer commas in the parentheses than dimensions. For example, to return a two-dimensional array of Doubles, use this as the return type :
Double(,)
but the coma and the closing parenthesis are automatically deleted when the field looses focus.
