Description

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
}
