Attached objects not displaying in Fiori

Hi,

Calling all Fiori / workflow gurus. We testing the Fiori inbox - and it looks great! - but there's a problem.

We cannot see objects that are instantiated in the workitem container.

In this particular case, we have a simple decision workitem with one button. An instance of ZCL_NOTIF also exists in the step container, but you cannot see it in the Fiori screen.

However, you CAN see this object attachment in the good ol' SBWP screen.

Does some more configuration need to be done?

Or does the 'attachments' tab in Fiori only ever show items from _Attach_Objects?

We are running NWBC 5.0

thanks

Paul
