I am attempting my first extJS applications so this is basically a learning project. I have attached a file containing a short example where I want to load a listview from a json data store. The listview is rendered by without showing any rows. It does correctly call the url and data is returned. So I have the following questions:
1) How should the params object be configured that is passed to the store load() method?
2) Are the name/value a pairs in the params object just turned into query string parameters
3) Do I required a callback function to load the listview or is that done automatically? If it is not done automatically how should it be done?
