I leave this for Matt, he is Binding guru :) I just removed type annotation from VO
class EmployeeOptions { public var firstname; public var lastname; public var country; } I see no error.... Stay tuned.. -abdul -----Original Message----- From: Tom Fitzpatrick [mailto:[EMAIL PROTECTED] Sent: Tuesday, March 15, 2005 6:58 PM To: flexcoders@yahoogroups.com Subject: RE: [flexcoders] ComboBox databinding Hi - Your example works fine, but when I try to achieve a similar binding using a value object defined as an external class, I get a type mismatch error: "Type mismatch in assignment statement: found Object where String is required". Here are some more details of my test setup. I have a value object defined as a class: class EmployeeOptions { public var firstname:String; public var lastname:String; public var country:String; } In a component called Employee, I've instantiated the class as: <EmployeeOptions id="vo"/> I'm trying to bind it from text fields and the comboBox this way: <mx:Binding source="firstName.text" destination="vo.firstname" /> <mx:Binding source="lastName.text" destination="vo.lastname" /> <mx:Binding source="countries.value" destination="vo.country"/> To return values to my component, I've created a delegate called EmployeeDelegate. This is instantiated in the component as: <EmployeeDelegate id="delegate"/> I'm trying to call methods in the delegate to populate the component with constructions such as: <mx:Label id="Name" text="{delegate.getEmployeeName(vo.firstname,vo.lastname)}"/> This setup works just fine with the text fields, but the comboBox gives me the type mismatch error when I use the above bindings.
