In factorypmi, I used the .isPropertyDefined method. It is missing in Ignition though. How can I recreate this method in Ignition, or can it be added back?

The isPropertyDefined method exists for any component that has dynamic properties. It should be there. It works for me in 7.1.6.

Ahh, I had a timer script being checked. I moved it into a container, and all was fine. Thanks.
