Error in 'PivotProcessor': Unable to fetch datamodelreport REST endpoint

Whenever I try to save a report/dashboard (Data Model and Pivot Tutorial) the view screen gives me tthe following error:

Error in 'PivotProcessor': Unable to fetch datamodelreport REST endpoint '/servicesNS/admin/search/datamodel/pivot/Tutorial' from 'https://127.0.0.1:8089'

I've changed all data models from private to global!

And I think it is correct that the report/dashboard is trying to use a data model called Tutorial.

Version: Splunk 6.0

See http://docs.splunk.com/Documentation/Splunk/latest/PivotTutorial/Buildtutorialdatamodel (Create a new data model --> 2)

Here you say that the the id of the data model should be "Tutorial".

I hope you can reproduce the issue when you go through your own tutorial.
