Hello!
I am trying to build a simple element relative trend in ProcessBook. I perform the routine steps of selecting an AF Database, AF Element, and an AF Attribute. When I click [OK] I get a blank trend and the element attribute "E.Temperature" says "Unable to cast object of type 'PISDK.PISDKClass' to type 'PISDK.PISDKClass'". I have built plenty of element relative displays without a problem and am not sure why this is happening now. BTW the result is the same regardless of the AF Database, AF Element, or AF Attribute used to build the trend. Any feedback is welcome.
