About Run Time Permission

 Recently i tested something about permission on TW ver5.

 1) i prepared a Mashup which it just contained a LED display widget and linked with a random value by a Things(service).

 2) i created a new user account and access the above Mashup, i could access it but i couldn't see the value result.

 3) then i modified the Things'(service) Run Time Permission which it invoked by the above Mashup. 

     And i use the new user account then access the Mashup again, i can see the value in the Mashup.

It means that the new created user account has the Design Time's Read Permission only 

and hasn't Run Time (Service Execute Permission) (by default).

For resolve it, i have to add the Thing's Run Time permission which invoked by Mashups, 

then i can see the result from Thing's service ?

Thanks and have a good day.
