Hi Eduardo,
Indeed, I am deleting the value of that attribute, the attribute is still there.
Yes, but it does not let me to assign that value (NullIdentifier()), to that attribute.
And when I see that i don`t have a value assigned to that attribute I presume it`s a NULL one, don`t really expect to assign the NullIdentifier().
But as I said before, on the other environment, where we deployed, the data in DB is correct, on those records we have a NULL value for that attribute.
Br,
Stefan
