> It isn't possible to set an empty context using 'contex' parameter of PageLink. It always
treats null and zero length array/list in the same way - asks the page about its activation
context via onPassivate. I think that only null should trigger onPassivate.
> Example
> <a t:type="PageLink" page="test" context="context">page link</a>
> public Object[] getContext()
> {
> 	if (test == 0)
> 		return new Object[] {"1", "2"};	// context will be ../test/1/2
> 	else
> 		if (test == 1)
> 			return new Object[0];	// onPassivate will be asked but context should be empty IMO
> 		else
> 			return null;	// onPassivate will be asked, ok
> }
