I'm trying to reject changes on a newly added entity (expecting breeze to set entityState to detached). Most times it works, but once in a while (mostly after I have already performed an entity create and reject), the rejectChanges call will fail because there is a null reference to the entityAspect.entityManager property.
I am getting my entity instance through "resolve" of ui-router on abstract parent state. Then in the abstract parent controller, I assign that instance to $scope. From then on I deal with $scope.myEntity instead of the resolved variable in my constructor. When I call entity This is my resolve function:
resolve:{
myEntity:function(sharedEntityManager,$stateParams, $q){
return $q.when(sharedEntityManager.getMyEntity($stateParams.entityId))
.then(function(myEntity){
if(!myEntity && myEntity.entityAspect.entityState.isDetached()){
$q.reject();
}
else
{
return myEntity;
}
});
}
}
Then in my parent abstract controller, I call this:
$scope.myEntity = myEntity;
The error I get showing null entityManager...
TypeError: Cannot read property 'isRejectingChanges' of null
at __using (breeze.debug.js:449)
at EntityAspect.proto.rejectChanges (breeze.debug.js:3687)
The error seems to occur only after I have successfully done 1 cycle of creating entity, rejecting that entity. Then when I create another new entity, that new entity somehow goes from "Added" and having an entityManager, to "Detached" and null entityManager. I confirmed that in the resolve function, entityState is "Added", but in the controller constructor, the injected entity from ui-router is now "Detached".
Anyone familiar with this behavior and is there a work around?
Are you sure about the test in the then
function? It seems off to me. Do you really mean if(!myEntity && ...
or should it be if(!myEntity || ...)
