> with permission security enabled, a page with nested layout generates null
> pointer exception under the condition that a portlet in the inner most nested
> layout is denied access.
> For example: a page with root layout as oneColumnNoAction, inside this
> layout, this are portletA and a TwoColumnNoAction layout. under the
> TwoColumnNoAction, portletB at the left cell, and a OneColumn layout at the
> right cell. inside the OneColumn layout positioned portletC. if portletC is
> forbidden from the current user, while portletA and portletB are OK to see.
> Null pointer is thrown.
> In general, if *all* portlets (suppose more than one) under the OneColumn
> layout are blocked to the current user, Null Pointer error is thrown. To make
> null pointer go away, at least one potlet inside the inner most layout
> (OneColumn layout) has to be accessible to user. Another point to note is
> that, if the inner most layout (OneColumn layout) has no portlet fragment at
> all (means no <fragment type='portlet' .../>. the page is displayed correctly
> (i.e. only portletA and portletB apepar on the page, which *theoritically*
> should be the same for the display situation, from user point of view, when
> portletC is forbidden). Theory is that JS2 treats those two situations
> differently somehow.
