To use a timeout value other than 30 seconds, replace
myStore = new Ext.data.JsonStore({ url: "http://foo.bar.com", ... });
with
var myBigTimeout = 90000; // 90 sec myStore = new Ext.data.JsonStore({ proxy: new Ext.data.HttpProxy({ url: "http://foo.bar.com", timeout: myBigTimeout }), //url: "http://foo.bar.com", ... });
