We have 2 servers, Production and Development.
In the production server the above error does not occur.In the development server (which are up), the error is indicated, then banana = banana and banana != banana, depending on the order of variables
Following features:
When creating a form, the Field "Login" value is "x1234".
** Field Characteristics Value (formula) Return Value
** Login text> "Compute when compose" @ Name ([CN]; @ uppercase (@ UserName)) X1234
This form has a field type "Action HotSpot, which is invisible (hide) if the condition below is true.
The condition for the field is hidden (Hide paragraph if formula is true) is "@ Name ([CN]; @ uppercase (@ UserName)) = Login"; this condition its OK, now if I turn "Login Name = @ ([CN]; @ uppercase (@ UserName)) "does not OK.
The big problem is that the system is already in production with the 2nd option (don’t have error).
Note: There is no problem of blank or data type.
I count on the experience of you.
Imagine that the configuration or the domino server.
We are with version 5.0 of the Notes (and Domino Client)
