Note that I can access the objects that I populate using a
PropertyListView individually just fine.
What I am trying to do now is access them as part of a larger form so
that I can update multiple items at once. I was hoping to be able to
iterate through the items that the PropertyListView had rendered so
that I can update them one by one. That's where I'm failing. That Form
and onSubmit are defined outside of the PropertyListView.
I'm sorry if I'm not explaining this very well.
