ember-data

问题 I have a jsbin setup with my issue: http://emberjs.jsbin.com/sovub/3/edit From my example, in certain situations when I try to delete a subtitle and then save, I get the error: Attempted to handle event `pushedData` on <App.Subtitle:ember563:7> while in state root.deleted.uncommitted.

Strangely enough, the data is transmitted correctly parsed to the server. Code: DS.Transform.extend({ deserialize : function(serialized) { var array = []; if (Ember.isArray(serialized)) { serialized.forEach(function(item) { if (item.feldTyp === "DATE
