I have a table component that allows for row selection, and would like to use the oldValue functionality of the propertyChange scripting to bring up a warningBox dialogue when a user switches from a particular value to any other one. Is this possible in Ignition 7.9? Please let me know if I haven't explained myself thoroughly enough.

The actual behavior of the property change event in Vision is exactly the same in 7.9 as it is in 8.X. It's a base Java Swing event. You can access `event.oldValue` in any property change event handler, though as the documentation notes, it is not always accurate for all components.
