[Exist-open] looking for an existdb/xforms example

[Nate M. <np...@gm...>]

I know this is out there somewhere, but I've been searching without much
luck.  I'm looking for an xforms example that uses existdb to select an
instance document from a collection for the form to operate on.  The xform
would have an input to allow the user to select which instance document they
want to work on by some unique xpath value and the form would open that
instance doc for editing.

I think the way it works is  (assuming each instance document has a
unique-id value and all the documents are conform to the same schema so they
can be edited by the same xform) there's one xquery to populate a dropdown
list in the xform  and another xquery that's used to return the instance
document to the xform  when the user selects the unique id for the list.
after that, the xform has a document name and it's pretty straight forward.
Am I on the right path?

Thanks!
