Michael,
I've solved the problem with the get entity by id. When I put
/xxx.svc/type('1') my data provider compares the value from the entity (1,
without quotes) with the value from the URI ('1', with quotes) and they
never match. Maybe I broke something when translating the examples.
Best,
Sebastian.
