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:
I'm trying to bind it from text fields and the comboBox this way:
To return values to my component, I've created a delegate called
EmployeeDelegate. This is instantiated in the component as:
I'm trying to call methods in the delegate to populate the component with
constructions such as:
This setup works just fine with the text fields, but the comboBox gives me
the type mismatch error when I use the above bindings.
Help!

Hi,
I don't have the book so couldn't look at the code...I know code is
available somewhere online, but me being lazy :)
However, following code might help you...

Subject: [flexcoders] ComboBox databinding
I'm trying to create an application based on the LoanCalculator example in
the Webster/McLeod book.
Everything's working fine for simple bindings between text inputs on a form
and the value object. Where I'm having trouble creating a databinding
between a comboBox in the form and the value object. When the user selects
an item in the comboBox it should be stored as a string in the value object.
What's the way to accomplish this? All the value object variables are
public, as in the book example.
Specifically, what would the statement look like? A simple
example would be even better.
Thanks.
