Text Field Fallback

I am having trouble with a text input field with the text bound to a string tag in my PLC. In certain cases the text that is entered is not accepted by the PLC logic, so it over-writes the string value back to what it was immediately after being updated by Ignition. However, the field on the screen is still showing the old value. If I change the value again in the PLC it updates on the screen. When I test this in the designer it works perfectly, but when I save and launch the project it is not working correctly.

This is a cross-post. We’ll follow up on the other thread.
