I am having the same problem. I am creating a trouble ticket log where the first row must alway contain the action of opening the ticket. I am trying to set the field, actiontype, in the first row to always be "Open". I first tried to make a rule to set the value of a field with a condition position()=1, but this is not a valid expression. I next created a field with a default value of position(), but as stated in earlier posts, the value of the field would not increment at all.
At wits end
