Sort column only updated when GridField is viewed

[th3hamm0r]

Currently the GridFieldSortableRows::fixSortColumn() method is only called when getManipulatedData() is called, which means only when the grid is displayed.
But if an user creates a new record and gets redirected to the detail view of the created record, the getManipulatedData() method never gets called.
This leaves the sorting in an inconsistent state:
If the site uses caching or things like static publishing, it may happen, that in the time between the creation of a record and the view of its grid representation, the frontend renders the sorted list with the wrong order (because fixSortColumn has not been called until now) and caches this wrong state.

I don't know if there is a clean solution without modifying the SilverStripe core (eg. the GridFieldDetailForm)?

This is expected behavior, your right the only way would be to poke into one of the extension points in GridFieldDetailForm or modify the core.
