Symptoms

NullPointerException in _loadCriterionList occurs when an application navigates from one instance of a data bound page to another instance of the same page. 

When this happens the binding layer does not know the page instance has changed and re-uses the existing binding container, including iterator positions and uncommitted data, for the second instance of the page.

There are 3 scenarios where this can happen:

1.  Recursive call to the same task flow that displays the same page.
2.  Return from a recursive task flow call that returns to the same page.
3.  Return from a task flow and immediately re-call the same flow during the same request, displaying the same page.
