when i have a field.select from sencha touch that takes his displayFiled from a store, and then start the app, the Field.Select shows automatic the first record from the Store.
If i do the same in ext.js 4.2 but with a Filed.comboBox, it shows an empty combobox, only if you click on it it will show you the records.
What shall i do to let the combobox shows the first record from the store when i start the app?
