AFValue.GetAnnotation() always returns null

Hello everyone,

 

I'm currently working on a project, where i have to set and get annotations of certain afvalues. Setting the Annotation works perfectly, and i can see the annotation in the PI System Explorer. But when I try to read the Annotation using AFValue.GetAnnotation(), it always returns null, even if the AFValue.Annotated is true. In other programs i can see the annotation, but in my own I'm unable to read it.

 

Any suggestions?

 

Thanks in Advance!

 

 

 

regards, Wolfgang
