xforms:bind nodeset does not work if you have more than one instance in model.
I have attached 2 files
datatable.xhtml which comes in sandbox application
and
datatablewith2instances.xhtml : modified slightly to add one more instance in the same model. This instannce is not used anywhere in model or in body. After adding the new instance to model, the xhtml does shows empty tables.
with regards
