Mashup not showing properly for defined Users

Hello Everyone,

I defined an Organization, Usergroup and an User and setted the Homemashup for this User to one of my modeled Mashups. The problem is, when i log in as the User, the Mashup does load but it looks like in the picture below.

But it should look like this (when i log in as Admin):

I changed the permissions for all included entities (the things the data is read from and all Mashupcomponents -> one Master and two Mashups), allowing the user full access to the 3 permission types. The User also has an assigned Application Key.

Is there something i overlooked? Which permissions for which Objects are crucial for such a scenario being able to work properly?

Any help is appreciated a lot!

Regards,

Dominik
