fabio martelli commented on OLINGO-395:
---------------------------------------
Currently, if you perform a "valid" object create and then, before flush, you
perform a delete then both requests will be sent.
I mean, the following code
Order order = getContainer().newEntityInstance(Order.class);
order.setOrderID(1105);
getContainer().getOrders().add(order); // this will generate a create
getContainer().getOrders().delete(order); // this will generate a delete
getContainer().flush();
will generate
POST <service>/Orders
DELETE <service>/Orders(1105)
Without the statement "getContainer().getOrders().add(order)" POST (create)
request won't be generated but a single DELETE request will be sent.
Of course, in this case, if order 1105 doesn't exist, delete request will fail
(may be, depending on service implementation?).
> Java client should support the deletion based on locally created entity

> this line of code will issue delete request as expected:

> =======================
> DELETE
> https://xxxx.yyyy.com/EWS/OData/Me/Drafts/Messages('msg3_tobedeleted_chh')
> HTTP/1.1
> =======================
> but this locally created entity should (1) also create a DELETE request with
> the key that has been set, (2) or should immediately throw exception of
> 'invalid DELETE on the unattached entity' :
> Message msg2 = <locally created entity>;
> msg2.setId("sdfafdsds_chh");
> manager.service.getMe().getDrafts().getMessages().delete(msg2);
