It doesn't look like the list button in your example contains any data. In
order to bind to the selected item, you need to populate the list data. For
example:
<ListButton listData="['A', 'B', C', 'D']"/ selectedItemKey="foo">
When you call load(), the context should contain something like this:
{ foo: "B"
}
If you need to translate the value from the context to one of the values in the
list data, you can use a bind mapping. See:
http://pivot.apache.org/1.5.1/docs/api/org/apache/pivot/wtk/ListView.ItemBindMapping.html
You can apply this to the list button via the setSelectedItemBindMapping()
method.
