form the api document,"This hook is executed when the router enters the route. It is not executed when the model for the route changes." but I can't really understand it due to some confusion.
for example,here, I have route name "xxx.yyy" in route xxx, I set hook function： 'beforeModel','model','afterModel','activate','setupController'.debugger in each; the same to the route yyy.
then, when I start the debug, I found the call order is that:
'xxx:beforeModel'->'xxx:model'->'xxx:afterModel'->'yyy:beforeModel'->'yyy:model'->'yyy:afterModel'->'xxx:activate'->'xxx:setupController'->'yyy:activate'->'yyy:setupController'.
why the yyy:beforeModel is called ahead of the xxx:activate ???
as I know, if xxx:afterModel return a promise, it will wait until it fullfilled(or switch into the loading route), after the promise is done, to me ,it means we almost enter into the route xxx ,so the xxx:activate should be called next. but instead, the next is yyy:beforeModel actually
who can tell me the reason??
