I got a great question today about whether we could create a Label in a Product Template dialog that would conditionally display a warning message when a particular input is not incorrect. We of course have a variety of automatic checkers built into NX that can display NX Alert messages, but with a little bit of creativity we can certainly do this inside the dialog in a Label as well. This example walks through the basic "Visibility" control first, and then dives deeper into creating a dynamic string in the Label that incorporates an updated Expression value as part of the message string. Please let me know if you find this useful!
