Handlebars If statement inside each loses context

I have a Handlebars template, which is used inside EmberJS as a template for a certain Route. The Route provides a model like this: ``` { "Id": 50, "UserId": 2, "Name": "sdfq", "UserFullName": "Bla bla", "branches": [ {"Id": 2, "Name": "Test branch23", "ProviderId": 50, "AvailabilityId": 1}, {"Id": 3, "Name": "Branch nr 21", "ProviderId": 50, "AvailabilityId": null} ] } ``` For this model I render a template like this: ``` <table class="table table-bordered "> <thead> <tr class="active"> <th>{{language 'Id'}}</th> <th>{{language 'Name'}}</th> <th></th> </tr> </thead> {{#each branches}} <tr> <td>{{Id}}</td> <td>{{Name}}</td> <td> {{#link-to 'branch.edit' ProviderId Id tagName='button' class='btn btn-primary' }}<span class="glyphicon glyphicon-pencil"></span> Edit{{/link-to}} {{#if AvailabilityId}} {{#link-to 'availability.edit' AvailabilityId tagName='button' class='btn btn-primary' }}<span class="glyphicon glyphicon-calendar"></span> Availability <span class="glyphicon glyphicon-pencil"></span>{{/link-to}} {{else}} {{#link-to 'availability.add_for_branch' ../Id tagName='button' class='btn btn-success' }}<span class="glyphicon glyphicon-calendar"></span> Availability <span class="glyphicon glyphicon-plus"></span>{{/link-to}} {{/if}} </td> </tr> {{/each}} </table> ``` Everything renders fine for the first time and correct links are shown for correct rows. Now when I try to click a link `availability.edit` I get an error Uncaught TypeError: Cannot read property 'AvailabilityId' of undefined If i track down the error then it leads to nothing related to my code (an jQuery internal function). ``` Uncaught TypeError: Cannot read property 'AvailabilityId' of undefined ember-1.3.1.js:3936 ChainNodePrototype.unchain ember-1.3.1.js:3936 ChainNodePrototype.remove ember-1.3.1.js:3914 Ember.unwatchPath ember-1.3.1.js:4087 Ember.unwatch ember-1.3.1.js:4156 Ember.removeObserver ember-1.3.1.js:5406 (anonymous function) ember-1.3.1.js:23856 sendEvent ember-1.3.1.js:2351 Ember.Evented.Ember.Mixin.create.trigger ember-1.3.1.js:17629 Ember.CoreView.Ember.Object.extend.trigger ember-1.3.1.js:21769 superWrapper ember-1.3.1.js:1230 ViewCollection.trigger ember-1.3.1.js:21834 Ember.View.Ember.CoreView.extend._notifyWillDestroyElement ember-1.3.1.js:23348 Ember.merge.destroyElement ember-1.3.1.js:24337 Ember.View.Ember.CoreView.extend.destroyElement ember-1.3.1.js:23323 superWrapper ember-1.3.1.js:1230 Ember.CoreView.Ember.Object.extend.destroy ember-1.3.1.js:21803 superWrapper ember-1.3.1.js:1230 Ember.View.Ember.CoreView.extend.destroy ember-1.3.1.js:23657 superWrapper ember-1.3.1.js:1230 (anonymous function) ember-1.3.1.js:24782 sendEvent ember-1.3.1.js:2351 notifyBeforeObservers ember-1.3.1.js:2723 propertyWillChange ember-1.3.1.js:2549 set ember-1.3.1.js:2815 Ember.trySet ember-1.3.1.js:2884 (anonymous function) ember-1.3.1.js:6894 tryable ember-1.3.1.js:2245 Ember.tryFinally ember-1.3.1.js:1412 suspendListener ember-1.3.1.js:2248 Ember._suspendObserver ember-1.3.1.js:5435 Binding._sync ember-1.3.1.js:6893 DeferredActionQueues.flush ember-1.3.1.js:5650 Backburner.end ember-1.3.1.js:5741 Backburner.run ember-1.3.1.js:5780 Ember.run ember-1.3.1.js:6181 Ember.EventDispatcher.Ember.Object.extend._bubbleEvent ember-1.3.1.js:21515 handleViewEvent ember-1.3.1.js:21459 Ember.handleErrors ember-1.3.1.js:899 (anonymous function) ember-1.3.1.js:21450 jQuery.event.dispatch jquery-1.10.2.js:5095 jQuery.event.add.elemData.handle jquery-1.10.2.js:4766 ``` If i remove the if statement `{{#if AvailabilityId}}` and display two links all the time, they work fine. I have tried modifying the scope by using: ``` {{#link-to 'availability.edit' ../AvailabilityId tagName='button' class='btn btn-primary' }}<span class="glyphicon glyphicon-calendar"></span> Availability <span class="glyphicon glyphicon-pencil"></span>{{/link-to}} ``` But it does not seem to have any little effect, even ../../ had no effect (Which leads all suspicions to the if block, which is probably causing the error). Any hints are welcome.
