I'm implementing a propagator and it works OK when i search for a solution
with Search but when it comes to Gist an exception is thrown:
Space::clone: Attempt to invoke operation on failed space.
This is what i do to modify the domain of the variable and check whether the
modification is valid:
ModEvent me = x1.gq(home,constantValue);
I can assure that the propagator returns ES_FAILED (a std::cout before the
return ES_FAILED line) when it has to and doing some extra tests i found out
that if instead of modifying the domain of x1 i just check whether the
variable's domain is empty the exception disappears.
It would be something like:
If some extra info about the propagator is needed just let me know, thanks
in advance for any help.
