I have an Ext grid that contains a data.Store using an XmlReader.
The data.Store uses a proxy that calls a java method to retrieve data from the database.
If the java method produces an exception (Query Timeout, etc) what should be passed back to the data.Store from the java method and how should the data.Store handle that response so that a user is notified that his query timed out ?
Or how can the data.Store handle a response that has 0 results ? So the users knows his query did not return anything ?
