Hi,
Please see the sample.
The differences:
1. ForceSelection="false"
2. New code of onAfterRender function.
var onAfterRender = function () {
this.onLoad = this.onLoad.createSequence(function () {
if (this.store.getCount() == 0) {
Ext.Msg.alert(
"Not found",
"Not found",
function () {
this.focus();
},
this
);
}
});
}
