I can manage design-time and run-time priviledges, I can also set default Mashup for a user,
but can I block access to the Composer as a whole for certain users,
and only allow them to use their Mashup?
I would like an answer to this as well.
I am also wondering the answer... is there easy way to completely block user's access to composer? wanna grant runtime access only
Current version of Thingworx (6.0.4) does not allow this. There is an enhancement request tracking internally to give this option. No specific timeline for this feature is currently available.
