Ralf, are you planning on anymore fixes for this?

It looks like the immediate issue is handled with item update failures.

You detail some other issues with index pages. You state:

"when we have an 'id' field or a Link property that links to a Class that has no
key property"

I assume this would be generated by somebody editing the URL directly right?
The result of a search using the search page should never cause this.

In any case, maybe that should be a different ticket and this ticket can be closed?

I am planning a beta on 1 June.
