Hello Thomas,

This year the Q2 release is expected in June, most probably within the first half of the month.

We are indeed planning some attach/detach improvements for Q2 2012. In fact, it will be helpful if you could share your scenario with us so that we can test our ideas against it - and enhance the chances for your case to be supported. You can do so through a support ticket as well, in case there is anything you wouldn't like to share publicly. 

I am looking forward to your feedback.

Kind regards,
Ivailo

Hi,

I have a scenario where I want to update an entity that comes through a call to a web service as a Json object. I deserialize the json into an entity object, and I'd like to attach this entity to a context in order to update it in the backend.

Thanks,

Alexis

Hi Alexis,

I am copying and enhancing the answer you have received on the other thread you have stared about ObjectNetworkAttached.

In general we are offering two approaches for attaching an entity:
1) ObjectNetworkAttacher - this option is available only for the old ObjectScope API.
2) Attach/Detach to contexts - a new functionality implemented for the OpenAccessContext. Stage 1 of it is available as described in the documentation article in Q2 2012. Stage 2, allowing you also to attach entities that are not known for a context (for instance deserialized objects in an N-Tier scenario), is planned for Q2 SP1, about to be released by the end of June.


Greetings,
