Current behavior: 1. Actions defined in the model, or in the body *adjacent* its input, populate the model correctly. 2. Actions nested within their input, with an explicit `ref` attribute, fail to update the view. This is because there is a hidden HTML input representing the action (distinct from the input representing the model value), which the current behavior selects. 3. Actions nested within their input, *without* an explicit `ref` attribute, replace the entire descendant tree of the model with the geopoint value. The cause is identical to the explicit-ref case, but the erroneously selected input has no `name` attribute. This causes the model update, in `Nodeset.setVal`, to evaluate against a nodeset resolving to the root `data` node.

Current behavior:
refattribute, fail to update the view. This is because there is a hidden HTML input representing the action (distinct from the input representing the model value), which the current behavior selects.refattribute, replace the entire descendant tree of the model with the geopoint value. The cause is identical to the explicit-ref case, but the erroneously selected input has nonameattribute. This causes the model update, inNodeset.setVal, to evaluate against a nodeset resolving to the rootdatanode.A couple open questions:
Should the third case described above ever be allowed to happen? My instinct is that we should never allow calling
setValon a node with children.How does this affect performance? It's definitely doing more work. It seems fine on my obviously small test form, but I'm not sure how much it'll impact larger or more complex forms.
