Subject Re: simultaneously run update handler and update doc content
Date Wed, 20 Nov 2013 07:48:37 GMT
First problem is that your update function works with `doc` argument -
that is the stored within database document -, not that you had sent
with PUT request. To process the request payload you need to work with
req.body data, but in your case this isn't need to.

Second is that both text and timestamp have actually changed - take a
look on them one more time (;

Before:

{"_id":"testid","_rev":"5-71ee77bc43fc698a935abc60dc33a82c","type":"profile","text":"hello
123",
"serverISO8601time":"2013-11-20T07:29:35.497Z","serverTime":1384932575.496999979}

After:
{"_id":"testid","_rev":"6-6726469319fc80710ef15d0df6dd6320","type":"profile","text":"hello
123",
"serverISO8601time":"2013-11-20T07:31:58.351Z","serverTime":1384932718.3510000706}
