How does one go about referencing objects on another canvas? For example I have a tab navigator with 4 tabs: Register Attendees Membership Payment Options
Inside the attendees tab I have a canvas: csAttendee with a datagrid: dgselectedOptions When the user submits the "pay" button on the payment options tab I call a function to validate their input and try and reference the columns array for the datagrid dgselectedOptions. Using csAttendee.dgselectedOptions gives me an error when I try to compile of "Access of possibly undefined property dgselectedOptions through a reference with static type mx.containers:Canvas." If I try Attendees.csAttendee.dgselectedOptions gives me "Access of possibly undefined property csAttendee through a reference with static type mx.containers:Canvas." If I try just dgselectedOptions it compiles, but when I click my payment button it gives: "Cannot access a property or method of a null object reference." Even though I can click on the Attendees tab and the datagrid is there and populated.
