dispatching of tokens can happen too early #32

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
A token that is a condition tied to a goal can be dispatched even though other 
preceding conditions are not observed.  

This is es-ecially true in the case where one condition is not dispatched (e.g 
on an Observed timeline) and starts before another condition which is 
dispatch-able. In such case one can often see the diapatch-able condition being 
sent even though the observable condition was not yet met.

We need to implement guarding mechanisms in order to protect from such 
situation.

This bug was seen in the lsts.nddl model from revision r1388  
It can be resolved by protecting the dispatched token within an if guard that 
tests the start time against TREX_CLOCK but should be handled in a more natural 
way in the future.
