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...

###mxBindingTest.mxml###
mx:Application width=800 height=600
xmlns:mx=http://www.macromedia.com/2003/mxml; 

!-- Form contains user input controls. --
mx:Form label=Employee Information
mx:FormItem label=First Name
mx:TextInput id=firstName /
/mx:FormItem
mx:FormItem label=Last Name
mx:TextInput id=lastName /
/mx:FormItem
mx:FormItem label=Department
mx:TextInput id=department /
/mx:FormItem  
mx:FormItem label=Email Address
mx:TextInput id=email /
/mx:FormItem
mx:FormItem label=Country
mx:ComboBox id=countries 
mx:dataProvider
mx:Array

mx:StringUSA/mx:String 
/mx:Array

/mx:ComboBox
/mx:FormItem
/mx:Form

!-- The myEmployee data model --
mx:Model id=myEmployee
name
first/
last/
/name
department//
email/
country /
/mx:Model

!-- Properties of user interface controls are bound to the
myEmployee data model using mx:Binding tags --

mx:Binding source=firstName.text
destination=myEmployee.name.first /
mx:Binding source=lastName.text
destination=myEmployee.name.last /
mx:Binding source=department.text
destination=myEmployee.department/
mx:Binding source=email.text destination=myEmployee.email/
mx:Binding source=countries.value
destination=myEmployee.country/


mx:TextInput text={myEmployee.country}/


/mx:Application



Notice how combobox box is bound to a Model and Model is bound to
TextInput...

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 mx:Binding/ statement look like? A simple 
example would be even better.

Thanks.

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..

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.

Help!

- Tom

That worked - thanks!
I'm still troubled as to why I can't set types for the variables in my 
value object, though - if anyone has an idea.
