This should work, but there might be a problem with the above XPath
expression. The context of the "noteset" expression is the node bound
to the select1. So position() will return 1 in this case, and not the
position in the repeat. In this case, the xxforms:index('repeat-id')
extension function should do the trick.

Alex,

Thanks.  Maybe I'm missing something else then. I swapped out the
following as you recommended. The second select1 list for all nodes
changes to whatever index you are currently at:

nodeset="for $pos in index('repeat') return
instance('genre-select')/genre[@auth =
instance('genres')/info[$pos]/@authority]"

for

nodeset="instance('genre-select')/genre[@auth =
instance('genres')/info[xxforms:index('repeat')]/@authority]"

was just not working because of the context change. What you can do
here is to declare a variable right after the <xforms:repeat> that
contains the current position, and use it later in your nodeset
expression. I have updated your example with this; you'll find it
attached.

So this requires version 3.7 in order to use xxforms:variable?

Thanks,

Yes, exactly, you will need a nightly build for this (which is very
close to the upcoming 3.7).
