Es necesario usarDS.hasMany apuntando a unDS.Model cuando un modelo contiene una matriz? ¿Incluso si los elementos de la matriz no son realmente modelos (sin identificadores o puntos finales propios)? ¿Hay alguna manera mejor?

estoy usandoDS.hasMany, pero mi extendidaDS.RESTAdapter Me está lanzando un 404 tratando de acceder al modelo, aunque nunca llame.find en ello, yhasMany se llama con{ embedded: true }. Veo este error por primera vez (aparentemente en relación con este modelo, ya que desaparece sin él):

Uncaught Error: assertion failed: Emptying a view in the inBuffer state is not allowed and should not happen under normal circumstances. Most likely there is a bug in your application. This may be due to excessive property change notifications. ember-latest.js:43

¿Qué significa esto y qué podría estar causándolo?

Aquí está la traza de la pila:

Gracias por cualquier ayuda.

Actualizar: Este violín obras (con ejemplo dedocs), pero ¿cómo podrían representarse esos objetos si las etiquetas no son modelos reales (es decir,no tengo identificaciones)?
