Duplicate Multiple Window Instance

I have a tag change script that watches a string tag and on value change I have it open an instance of a window. The windows location is set dynamically and I pass the desired parameters in and they pop up where I need them.

However, If there is a window open in position 1 and the same tag changes while its current instance is up, it creates another instance in the same position and changes the text on both.

Is there a way to open only one instance and have the text change without having another instance open directly on top of it for the same location?


You could use system.nav.openWindow instead of system.nav.openWindowInstance.
