Hey, I've got a simple window that's throwing an error in the multistate indicator property binding. Here's the XML. [window.xml](https://forum.inductiveautomation.com/uploads/short-url/pngLD0yF9oHOZsogXyOWnhpCikw.xml) (37.2 KB) Everything looks correct inside the XML and the only change here from a project that worked should be 'changing the tags the tank binds to and its position'. ---

Where are you seeing Cylindrical Tank 1 in the xml? ---

It removed the listener/binding from the multistate because `Cylindrical Tank` didn't exist. ---

Hmmm, ok -- why is the name of the tank changing? ---

Beats me. lol. Seriously, I tried changing the name to `Cylindrical Tank Test` in the XML and it imported as `Cylindrical Tank Test 1` ---

So, offhand, I believe this is a bug on setting items from XML. Can you post an export of the window instead? ---

Try importing this one. You'll need to update the tank bindings. [Leor\_test\_2025-02-24\_1318.zip](https://forum.inductiveautomation.com/uploads/short-url/u0PL9ZwNntmaVlVCxDJrRk2O5rv.zip) (9.2 KB) ---

I've run through a bunch of improvements to now end up with the following XML: [nwindow.xml](https://forum.inductiveautomation.com/uploads/short-url/buDYEw833lXuMvE8r5hPP8BzRdm.xml) (25.5 KB) It _should_ just have the expression bindings for tank value and capacity changed (according to my internal differ, Changes in o: - Removed: capacity expression binding to 10000 - Added: capacity expression binding to {[default]Local\_Tags/A1}+{[default]Local\_Tags/A2} - Removed: value expression binding to {[default]1\_A1-1\_A10/1\_A1}\*{[default]1\_A1-1\_A10/1\_A2} - Added: value tag binding to [default]Local\_Tags/A1) But I'm now seeing a deserialization error. @pturmel @JordanCClark any ideas? ---

- I would make this into a [template](https://www.docs.inductiveautomation.com/docs/8.1/ignition-modules/vision/vision-templates) - Properties within the template components should point to tags using indirect addresing. - Top level parameters of the template hold just enough info to drive the indirect tags.
