Back button not working after changePage()

Back button not working after changePage()

I am having the following repeatable problem.

1. Click <List> button to enter listview page.
2. Click listview item which triggers changePage().
3. Click <list> button to enter listview page.
4. Click <Back> button on listview page. Button doesn't respond.

Running in Android emulator and Chrome 10.

Code follows
