I am converting a vision project to perspective and having trouble figuring out how to make something work.

I had a client event tag change script that triggered a popup window to open in the client. The tag is a query tag linked back to a primary key in a mySQL database. When a new entry goes into the database, the tag value changes and fires the client event script to open a popup window. The popup was used as an alert to let the shop floor operator know they had received new information. Is there a good way to replicate this in perspective?

Since tags are just in the gateway, you can’t have a tag change event trigger a popup in Perspective. However, you could bind a property in your view to that tag and then set up a change script on that property to trigger the popup.
