Ahhhh....Ok Kartsen,

I did what you said and now all works fine. Thanks a lot!

What do you think about my proposal to rewrite my lost :( experimental nodes ArrayDistinct and ArrayBoolean that I mentioned in my previous post ?

Unfortunately, for the time being I can't deal that effort.
Maybe when Max's will release 1.0 version of Elephant...

Have a nice day.
