I already said that this will not work.  you are using the default 
variable for visibleWhen ... that's a Collection containing the current 
selection.  <with variable="selection">...</with> would give you the 
ISelection directly.

Your property tester is typed for a Boolean ... it will never get 
called, since a Collection is not a Boolean.
