Missed "pulse"?

Easy trap with invalidation listeners. If you don't get the property 
value after invalidation, the property remains invalidated and 
subsequent changes won't trigger another invalidation. To fix this, 
simply get the value (for nothing), or switch to change listeners...

You probably know this by now but maybe somebody else didn't...
