Ok. I don't understand if any issue is still in place.

Although it is not related with the latest issues, just in case,
I remind you that if you subscribe to an item in MERGE mode
and the Data Adapter only sends "delta updates" for the item
(i.e. it only includes the changed fields in the update events),
if you then switch to RAW mode, the "delta updates" will no longer be managed
and any field not included in an update event will be supplied with a null value to the client.
