Vision module on Ignition 8.1.16 This binding is on a template that is used on multiple other windows. I have a Programmable Simulator Device that is supplying the OPC values. The values for these boolean tags are just set at static true/false. The tags are combined under a UDT. The tag quality is good and I am able to read/write each tag value from the tag browser. My parameter to the template is a string that I use to create indirect bindings to the tags of interest within the UDT. I have internal template properties bound (bidirectionally) to the UDT tags using indirection. For instance, `Hi_Alarm_En` (bool) and `Hi_Alarm_Delay` (int). The internal template properties are then bound to individual component properties. For instance, `Hi_Alarm_En` is bound to the control value (bidirectionally) and indicator value of a 2-state toggle button. This is repeated 3 times on the template for `Hi_Alarm_En`, `Lo_Alarm_En`, and `Signal_Alarm_En`, along with numeric input boxes for the delay inputs for each. I did not have the issue with the low or signal tags, and the issue with the hi tags is intermittent. I just opened up designer (for the first time today) and no errors (no change to the project since posting). --- _[View the full topic](https://forum.inductiveautomation.com/t/bug-multi-state-button-toggle-button-control-indicator-bindings-programmable-simulator-device/59138)._
