Setting Instance value within nested <repeat>

Well Formed Ones:

(OK, I'll never open with that one again.)

I'm not sure if I am observing an XForms issue or
Orbeon, as I only have Orbeon installed.

I am unable to set instance values within a
trigger created within nested repeats.

Does <setvalue ref="" value=""/> change the context
to ref? If so, how can I specify the context of
<repeat> ? (The code snipped at the end I hope
is all that is needed to explain.)

Thanks for any insights,
Hank

along with this data:

http://nees.ucsb.edu/xml/stats.xml

Here is the inner-most table element where I can output
the dateTime, but using the same xpath to attempt to
set the value in the instance data I want to submit, I get:

! XForms error: Invalid date "" (Too short)

I have tried several ways of casting and bound all data types
to xs:string, but I get the similar errors.

<xforms:repeat> ...
  <xforms:repeat> ...

  <td>
    Count: <xforms:output value="count"/><br/>
    Greatest: <xforms:output value="greatest"/> (ml)<br/>
    Deepest: <xforms:output value="deepest"/> (km)<br/>
    <xforms:output value="start-date"/><br/>
    <xforms:output value="end-date"/><br/>
    <xforms:trigger>
      <xforms:label>Select</xforms:label>
      <xforms:action ev:event="DOMActivate">
        <xforms:setvalue ref="instance('events-query')/start-date" value="start-date"/>
        <xforms:setvalue ref="instance('events-query')/end-date" value="end-date"/>
        <xforms:send submission="events-submit"/>
      </xforms:action>
    </xforms:trigger>
  </td>

  ...</xforms:repeat>
...</xforms:repeat>

which in many cases is not what you want.

Use the extension function xxforms:repeat-current() to obtain the
context of the current repeat iteration, e.g.:

   value="xxforms:repeat-current()/my/value"
