title: ExtJS Unmask after data load
body: <p>I am using a JSONStore in ExtJS and loading data by using setting the URL config and then calling the load method, is there anyway i can unmask the form only once the data is loaded. At the moment it unmasks after the load method which doesn't work since the load is async. But what i want to do is only unmask after the async operation has completed. Any Suggestions welcome.</p>
