Model attribute named 'error' causes exception

[ZebraFlesh]

Given the following model definition:

import DS from 'ember-data';

export default DS.Model.extend({
  state: DS.attr('string'),
  error: DS.attr('string'),
  progress: DS.attr('number'),
  complete: DS.attr('boolean', {defaultValue: false}),
  canceling: DS.attr('boolean', {defaultValue: false})
});

I encountered the following exception when upgrading from ember-data 1.0.0-beta-19.1 to 1.13.4:

Error: Attempted to handle event 'didSetProperty' on <task-status:16> while in state root.loading. Called with {name: error, oldValue: undefined, originalValue: undefined, value: null}.

Once I renamed my model's "error" attribute to "errorMsg", the exception no longer occurred.

I'm seeing the same problem.

I'm surprised this error started occurring with "1.13.4". Ember Data has had an error property on DS.Model for a long time. @tchak any idea whats going on here?

[tchak]

@bmac no it have not... It is a new one. Maybe it was a bad idea. I am not exactly sure what would be the right thing to do here.
