Bug? Bug with List.Initialize2 ?

[Informatix]

I thought this code:

Dim ListeTas As List
ListeTas.Initialize2(Array As Int(0, 1, 2, 3))

...was similar to that one:

Dim ListeTas As List
ListeTas.Initialize
For i = 0 To 3
   ListeTas.Add(i)
Next

...but it seems it's not the case because the first case returns an error (Unsupported Operation Exception) when I try to remove the first element (ListeTas.RemoveAt(0)).

I don't know why Erel designed it this way, I think he might have been trying to make the Array and Lisr APIs similar.

Initialize sets the internal object to a Java ArrayList whereas Initialize2 sets it to a Java Arrays.asList(Object[]) which returns a fixed size List which is not an actual Java List but an internal type of List. I did at one time check its actual type, but I've forgotten what it is now.

I think

ListeTas.Initialize2(Array As Int(0, 1, 2, 3))

this one make a readonly list.

Sorry. I should have read it.
