The frontend should not end up in an endless loop. This is a case when a user opened a link to the Dataset from their Dashboard, but they don't have access (it's not published).

This happens on any page if the server responds with 401 Access denied and we need a solution.

The key problem is that we test the conditions for reload in both componentWillMount and componentWillReceiveProps. This is because in SSR we already have the data in Redux state and we don't need to reload data in componentWillMount, while in development we have to load here.

SSR needs only execute once (no loop). But this still writes the (error) state that is sent to the client.

Idea 1

Write to component state that we're received new properties and started loading the data. In componentWillReceiveProps we can check if we did the call for the same properties (e.g. for uuid) and avoid the call.

Update: this still doesn't work because Redux state ApiCall will contain the error response and there's no component state to compare to.

Other ideas?

I'm out of ideas. Suggestions, please.
