Hi,
I have been attempting to make use of <xforms:itemset/> to pre-populate a
selection list. I must not understand the examples very well, because I
can't seem to get it to work. Note, that the submit option as coded is just
a place-holder right now. I'm simply trying to have Chiba generate the page
so I can understand how it all works.
If you place both files (appended below) in the Chiba forms directory,
naming the src data one "SimpleOptions.xml" it should enable you to
reproduce the stack trace (also below).
Thanks in advance...

The simple form:
