Why does my custom element type error around locale being missing on the element types' model?

Question

I have made numerous elementTypes in my plugin that all work perfectly but for some reason one elementType keeps having an error when trying to view the Model's content or custom fields.

This is the error:

Property "Craft\Myplugin_OrderModel.locale" is not defined.

Everything looks exactly the same as all the other models that are elementTypes in my plugin.

All my plugins elementType models are using

public function isLocalized()
{
    return false;
}

but the issue still persists with that one Model.

Answer 1

That's interesting Luke, I had the exact same issue and spent WAY too long on it.

Even though I used a diff tool to see the difference between working elementType models and the one with the error I just did not catch the silly difference:

protected function defineAttributes()
{
    return array(

vs the working:

protected function defineAttributes()
{
    return array_merge(parent::defineAttributes(), array(

you need to add the parent attributes that includes attributes like locale :)

I knew that all along, but just didn't catch it on multiple re-reviewing of the Model.
