                        xtype: "form",
                        bodyPadding: 5,
                        border: false,
                        defaults: {
                            xtype: "textfield",
                            inputType: "text",
                            anchor: "100%"
                        },
                        items: [{
                            fieldLabel: 'Username:',
                            readOnly: true,
                            value: 'Admin',
                            name: "username"
                        }, {
i have external class named openDB.js with method getUserByUsername() 
here is small code how its will be used in other view and it works, but in my actuall view i cant set the Value of textfield. please help how to do that?
 openDB.getUserByUsername(user.username).then(function(userDetails) {
            me.setTitle("Welcome " + userDetails.mail + "!");
        });
i want to do something like this with  value: 'Admin' and so on...
i found some method on Sencha Forum, but can I use it??
setValue: function(value) {
        var me = this;
        me.setRawValue(me.valueToRaw(value));
        return me.mixins.field.setValue.call(me, value);
    },
