DS.store.find() using two params result in an error

i have a strange behavior:

If I call

this.store.find('uilabel', { locale: "en" });

it returns the result of /uielements?locale=en as I expect.

but if I add another parameter like

this.store.find('uilabel', { locale: "en", device: "mobile" });

I get this error:

Uncaught Error: Assertion Failed: Error: No model was found for 'device'

Ember correctly starts a GET-request to /uielements?locale=en&device=mobile which is responded

Does anyone know why this happens?

EDIT: Here is the uilabel-model. So far, it is as primitive as it could be :)

Application.Uilabel = DS.Model.extend({
    locale:     DS.attr('string'),
    key:        DS.attr('string'),
    value:      DS.attr('string'),
    device:     DS.attr('string'),
});

EDIT2: Sry, i could provide it by myself... here the JSON-response:

uilabels?locale=en&device=web

{
    "locale": "en",
    "device": "web",
    "key": "server_url_dialog_default_button",
    "value": "en_test"
}

Thanks

Your issue may be that the JSON response is not in the format that Ember Data is expecting. See http://emberjs.com/guides/models/connecting-to-an-http-server/. According to the spec, your JSON response needs to be in this format:

{
    uilabels: [{
       "locale": "en",
       "device": "web",
       "key": "server_url_dialog_default_button",
       "value": "en_test"
    }]
}

Since you're doing a this.store.find() and passing multiple parameters, Ember Data is expecting an array of results versus just a single result. Hence, it is interpreting device as an entire model, versus an attribute of uilabels.
