DetailViewer not updated with saved record

[wallytax]

I'm trying to create something similar to the complete application example and have a ListGrid and TabSet with "View" and "Edit" tabs. As soon as a record is saved, it automatically updates the ListGrid, but not the DetailViewer. ListGrid, DetailViewer and DynamicForm all use same DataSource.

Besides this, I was wondering whether the approach with "View" and "Edit" tabs (as used in the example) is really necessary. In my application I work with privileges and some records are read-only for certain users while others may be edited. I would not need the "View" tab if I could combine the two and have like a "read-only" property set to true on the DynamicForm if a user lacks edit privileges. Simply put: could I combine editing/viewing of a record and disable editing for the whole for?

A simple way to do this is just to display either a DetailViewer or DynamicForm in the same screen space depending on whether the record should be editable.
