Hi ak_nz and thanks for our reply. Yes, I used the really simple example of the ni forums article, added it to a lvproj and packed it to a lvlibp. The behaviour remains exactly the same when I call it via the project and the override settings (adaptor configured as RTE).
Interesting behaviour: If i call the vi from the lvlibp directly, it works as expected (-> Called via RTE).
I added the example...one sequence working, the other not...
