iPhone - full refresh / odd UI quirk after adding a new contact

[pavoni]

I'm seeing an interesting issue. When you add a new contact on an iPhone (ios 7) - the server correctly adds this to the database, but the behaviour on the phone is odd.

The initial protocol exchanges add the contact to the database (using a uid in the PUT that doesn't match the uid in the card!).

However there are another sequence of PROPFIND requests that make me think the phone has requested a complete refresh, followed by another GET of the card that was just saved. During this process the phone blanks the contact you've just saved (although you can re-open it from the list screen).

My guess is that as a consequence of the save the phone detects what it things is a problem - and starts a refresh. During that it decided the card it has added isn't there - and so blanks it. At the same time it does get the newly added card.

My guess was that this was some confusion of the PUT vs the vcard uid - in case that was the problem - but switching to creat the contact with the PUT uid doesn't seem to make a difference.

This doesn't happen on an edit - which works as you'd expect.

Anyone else looked at any of this?

This is iPhone specific - doesn't happen with the Mac Address book.
