I think this should work. I have a nested UDT. The parent UDT has a param called “Station\_Path”, and I copied the path of the UDT I want into the value for this param. But, the tag browser doesn’t jive, it just gives me an empty nested UDT in the instance:

There must be a way to allow for dnyamic pathing for children UDTs, right?

Thanks a bunch!!

I am also having this issue.

Is there any updates on this?

It's not possible to change a nested udt's typed by design. This is made more evident now than in earlier versions, by the typeid field being disabled
