I'm having troubles detecting property changes in nested controllers.
Here's my simplified code:
ActionCardController
ActionCardController = Ember.ObjectController.extend ActivatableHandles,
needs: ['actionCards', 'handle-connector']
HandleConnectorController
HandleConnectorController = Ember.ObjectController.extend
content: {}
testProperty: (->
@get('somePropertyThatChanges')
).property('someOtherProperty')
ActionCard template
<div ...
...
...
...
{{render 'handle-connector' this}}
...
{{controllers.handle-connector.testProperty}}
</div>
As shown, I have a nested "handle-connector" controller (with multiple properties) with its own view and template which needs to be rendered inside of ActionCard template. Everything renders and behaves fine within handle-connector context but I cant't seem to access testProperty in the parent controller (which is a computed property on nested handle-controller). I can only access the initial property value but once it gets changed in the nested controller, it does not refresh in the parent controller (ActionCard).
If I don't specify a model in the render helper, calling just:
{{render 'handle-connector'}}
...then the property gets refreshed in the parent controller as well and this approach works fine. But when I'm rendering multiple ActionCards, I get the error "You can only use the {{render}} helper once without a model object as its second argument". What's the correct way of dealing with this situation?
