I've got a form that I'm using to edit a user profile that uses two ComboBoxes which get values from two different stores. I create the form window and load pre-existing values into it like so:

Code:
var win = Ext.create('PPKC.view.profile.Edit').show();
var form = win.down('form');
		
// Load form values from record
form.loadRecord(record);
This loads all my textfields, but the combo boxes are blank. They load the store data when I click on them, but the previously saved value isn't displayed. I don't see in the documentation how to load remote data into a combo box before the user clicks on it. Is this possible?
