Hi guys, im trying to follow the manual steps for filtering an alarm status table. In the manual, it creates an associated data which can be used in the alarm filter script of the table. This works great, but when the associated data is bound to a parameter of the UDT it stops working. Looking at the console it cannot read the parameter’s string value, just returning None instead of “Group 1”. Any ideas where i might be going wrong?

What is your binding expression on the associated data?

Hi, it’s simply bound to the parameter. ![image](https://us1.discourse-cdn.com/inductiveautomation/original/2X/e/e13218b218a0b9707b8296796a37bcc43ecd06e0.png)

We have the same problem.

We tried [Associated Data in tags AlarmActive event](http://forum.inductiveautomation.com/t/associated-data-in-tags-alarmactive-event/14602/2)

Calling alarmEvent.getActiveData() gives : ‘NoneType’ object is not callable
