Activity Activation Problem: A minimum of 1 object(s) required error

Hi!

I'm trying to activate some changes that I did in an WD app that uses NWDI, and upon activation I am getting this error:

"Metadata of component GTINComp (Component Controller) is not valid! ContextElementMapping ... Role "MappedElement": A minimum of 1 object(s) is required"

Does anyone know why this happens and how to solve it?

Really appreciate it. Thanks!

    You have probably set the cardinality of the node to 1..n or 1..1 with InitializeLeadSelection to False.

    PS. This is not the Web Dynpro forum.

      Hi Pascal,

      I checked the context and it wasn't set that way. The thing is it works on local deployment, but when I try to activate the activity in DTR, it generates that error.

      Anyway, I've resolved the problem as well. There was a sync problem apparently (my code was suddenly decoupled in the main repository).

      Thanks for replying though!
