Currently, I am faced with the task of rendering a JSONP feed as an ExtJS component. I am uncertain about the most effective approach to take in this situation. Should I utilize the Ext.CompontentLoader feature, or is there a better solution available? Another option would be to make an Ajax call to retrieve the data. However, I have yet to determine which API call supports JSONP functionality. It appears that Ext.Ajax does not offer support for JSONP in ExtJS 4.
