I have downloaded and built the examples CDR's from 'Implementing custom AF 2.x Data References vCampus White Paper'.
Specifically, I am working with the 'String Concatenation Data Reference' example in a hope to resolve an issue I'm having.
After copying the DLL to my test server and registering it, I created an attribute, assigned the data reference as 'String Concat', added some settings, checked in and refreshed. As expected, I can see the result of the concatenation... all well and good.
However... if I try to use the attribute in an analysis that is periodically scheduled, the result is 'Calc Failed'; this happens whether the attribute has a tag reference or not.
So... the question is: is there a way to access the values from a CDR in another attribute?
