I know about debug.. but I haven’t used it!
Now it works.. the problem was on filter.
I try to explain it in my terrible English.
When I create a new document, the TV "gruppo" (whith Dropdown menu [ Document 1==1||Document 2==2 .. ]) is set by default on the firs value.
So I think that this Document have the TV "gruppo" set on 1.
But it’s not like that.. th Tv dosen’t have any value.
If I manually select the first name from Dropdown it works fine.
Thank you Mark, now I know to use debug..
