You are correct!
I was suprised when I first discovered that complcation of RT.
I am not part of NI so I do not know the full inside story but I will share my undstanding.
The property nodes execute in the UI thread. Bad for determinism.
The FP get stripped when the code is targeted, so no objects to act on.
I have managed to work around this detail in all of my RT apps.
The only sticky point had to do with having to translate a enum value to its associated string becuase I could not read the enum's strings. Even that can be handled by flattening the enum to a string and parsing.
Please feel free to post regarding what problems this causes and we may be able to help.
Always interested in the limits of my world,
Ben
