Hi Steven,

Thanks for the pointer.  I hadn't seen it before, but you're right, it
is similar to my problem.  I didn't know enough about XForms to come up
with the submission technique, but this still leaves me with the problem
of trying to share data across multiple models.

As I said, I may have more than one (or even dozens) of dynamic
selection lists based on separate models.  Maybe this is what I'm doing
wrong though.

In my example form, the select is manipulating instance values in model1
while the values to populate the select items are coming from model2. 
For a second selection list, the selection goes into model1 but the
items come from model3.  I guess I could lump them all together (I
thought I tried this, but maybe I did it wrong), but that doesn't really
seem like a good idea.

I suppose I could have an i18n model which pulls in all of the items and
other localized content that I need to display, but then have my actual
form data that I capture in a separate model.  Then the language
preferences could exist only in the i18n model where they're accessible
from the XPath context within the itemset as well as from whatever
selection mechanism I choose to put on the page.

I'll think about it a bit more and do some more experimentation.  Thanks
again for the link.

Cheers,

ast
