The type coming from the invoke VI reference node and the diagnostic data indicator look pretty much the same. Is there a way to force labview to cast one type to the other? This is preventing the Engine from building.
OK, so the Diag Data Ref is really just a strictly-typed VI Reference underneath. There has to be some way to convert the VI Ref coming out of the node to the Diag Data Ref indicator...
The underlying VI Interface Types seemed to be "off by one type". The Diag Data Ref type's underlying VI Interface Type was 1, it needed to be set to 2. The same sort of update was done for the Scale Ref typedef. Also, I needed to add the NationalInstruments.VeriStand.SystemDefinitionAPI.dll to the J1939 System Definition library. Everything is building with no errors for LV2015.
I am glad you solved the issue. I also found this problem when I upgraded to 2015. I made a change to the latest version of the source code on GitHub (https://github.com/NIVeriStandAdd-Ons/J1939-Custom-Device) that removes this problem from happening in the future. It basically uses data references instead of VI references to perform the same functions.
