PI Point not found Exception from AFAttribute.PIPoint generated from template

I've got some code that creates an AFElement from a predefined template. This template has a few attributes with configstrings to create pi points (\\%Server%\%Element%.%Attribute%.%AttributeId%;pointtype=Float64).

 

The issue is that whenever I try to reference the attribute's PIPoint property in the same process, I receive a "Unhandled Exception: OSIsoft.AF.PI.PIException: PI Point not found '\\[[server]]\[[element name]].47c64e77-dfa6-11e4-8f14-28924a26e092.[[attr-name]].692ce409-a456-5661-23c1-e0298a02377f'."

 

When I open System Explorer, I can see that I have a point with a value of "Pt Created." Template-defined analyses that reference that value also execute without error.

 

I've tried the following:

 

  • Check in the element repeatedly.
  • Check in the parent element repeatedly.
  • Wait a bit (1000ms).
  • Various combinations of the above.

 

At a loss of what else to try. Is this a cache issue? That would be bizarre given that I just created this so it should be a cache miss.

 

Thank you and happy holidays!
