My guess would be that you are trying to do
this in this_onBefore/AfterInitEvent?
If so, it's too early for dynamic anything.
Since dynamic criteria is kept on a session
by session basis, a session needs to exist
prior to dynamic criteria methods being called.
If you need this behavior on just a few pages
I'd put the code in this_onBeforeDataObjectExecuteEvent
of the pages using the dataobject.
If you need this behavior on several dataobjects,
I suggest creating your own page listener and
implementing onBeforeDataObjectExecuteEvent,
then add that listener to the page in an
overridden init() method. You want to do it
in init because when the page get's cloned
into a new thread you need to re-add the
listener.
