Difference between a submission element using bind and a ref

Hi,
I tried some mailing list search but that wouldnt help. Can someone tell me what is the difference between having a xf:submit using a ref and using a bind.

For example, the difference between this
<xf:submission id="auto-complete-serial-number" method="get"
        ref="/item/context/number"
        action="/xforms/getNumbers.action"
        instance="serial-numbers" separator="&" replace="instance"
        validate="false" />

and this
<xf:submission id="auto-complete-serial-number" method="get"
        bind="ctxNumber"
        action="/xforms/getNumbers.action"
        instance="serial-numbers" separator="&" replace="instance"
        validate="false" />

Where I have bound ctxNumber to item/context/number using xf:bind control.

When I use a ref, I am getting a "Control not bound to external node...error" after the response has come back and I try to fill some other fields. When I use a bind that error doesnt occur, however If I am not wrong, when I use ref, only that snippet of xml alone is sent for the get request? I would like that to happen in my case. So could someone
a) Tell me what the difference is between the two
b) Why do I get Control not bound errors in first case
c) How to get it work with a "ref" construct since I want only that snippet to participate in a get/post request.

There shouldn't be any, but there may be a bug.

The ref should be enough to achieve that.

Can you try a nightly build?

Can you send a reproducible case for the sandbox?
