[CLOSED] Property for Usercontrol that uses Ext controls withing a panel
I'm trying to add a public property to a UserControl for setting the text of a ext:Button/Label. Basically this works however, when in our case, there's a ext:Panel around the ext:Button. In this specific case the ext:Button isn't constructed yet (null) and it throws an error. How to prevent this?
