Angular2 RC1 child routes defined but not recognized
Note that the path can only be 'heroes'. if I change to [routerLink] and @Routes to '/heroes' it won't work. Can some help explain why?
Actually paths in child router can contain "/" as prefix but changing routerLink to "/heroes" made it not work because "/" prefix in navigation path will be resolved using root router and does not have "/heroes" path. "heroes" path worked because it will be resolved using current router and you defined that path in current child router.
this._router.navigate(['hero/'+hero._id]);
Calling "navigate" without a segment will be resolved using root router. It means you want to do absolute navigation. Obviously this will not work.
this._router.navigate(['hero/'+hero._id],this.currSegment);
This also did not work because you are at HeroesComponent and "heroes" segment, there is no router configuration in the component. The correct call should be:
this._router.navigate(['../hero', {_id: hero._id}], this.currSegment);
