ember.js - Emberjs adding objects to ArrayController, server query is immutable -

i'm trying add objects emberjs arraycontroller. have "create" action fires when button pushed. works fine can't seem add element this.pushobject function arraycontroller. error message:

uncaught error: result of server query (on app.software) immutable.   

i guess because i'm using restadapter load data , not i'm adding elements manually?

here controller , create action.

app.softwareindexcontroller = ember.arraycontroller.extend({     sortproperties: ['revision'],      create:function(){         var revision = $('#software_revision').val();         var doc = $('#software_document').val();          var software  = app.software.createrecord({           product_id: 1,           revision: revision,           doc: doc         });         this.pushobject(software);      } }); 

here route

app.softwareindexroute = ember.route.extend({   setupcontroller:function(controller){     var product_id = 1;     controller.set('content', app.software.find({product_id:1}));   } }); 

here model , store

app.store = ds.store.extend({   revision: 12,   adapter: 'ds.restadapter' });  ds.restadapter.configure("plurals", {   software: "software" });  app.software = ds.model.extend({   revision: ds.attr('string'),   doc: ds.attr('string'),   verified: ds.attr('boolean') }); 

and here template view create form , list of software

<script type="text/x-handlebars" data-template-name="software/index">   <p>   <fieldset>     <legend>create new software revision</legend>     <label for="software_revision">revision</label>     <input id="software_revision" name="software_revision" type="text" placeholder="">     <label for="software_document">document id</label>     <input id="software_document"  name="software_document" type="text" placeholder="">        <button class="btn btn-success" {{action create}}>create</button>   </fieldset>   </p>     {{#if length}}   <table class="table">     <thead>       <tr>         <th>revision</th>         <th>created</th>       </tr>     </thead>     <tbody>       {{#each controller}}           <tr>             <td>{{revision}}</td>             <td>{{createdat}}</td>           </tr>       {{/each}}      </tbody>   </table>    {{else}}   <div class="alert alert-info">     <button type="button" class="close" data-dismiss="alert">&times;</button>     <strong>no software revisions found!</strong> start creating new revision above.   </div>   {{/if}} </script> 

does know proper way add new object arraycontroller store? thank you!

this works way if change route doesn't use restadapter

app.softwareindexroute = ember.route.extend({   setupcontroller:function(controller){     var product_id = 1;     controller.set('content', []); // not using restadapter load data   } }); 

i had same problem. looks content returned app.software.find() immutable array. able around getting content of immutable array returned mutable array.

for example:

in ember 1.0.0 + ember data 1.0.0 beta 3:

this.store.find('software').then(function (softwares) {   controller.set('content', softwares.get('content')); }); 

and guess version working @ time of post:

controller.set('content', app.software.find().get('content'));
