[flexcoders] Casting Value Objects

[Pete Capra]

Hi there, 

 
I'm having a little 
trouble casting results from an RPC to a ValueObject. For example, I'm returning 
an array of objects from CF the object has two properties and I have created a 
VO class accordingly:
 
package 
com.xxx.xxx.model {
 
    
[Bindable]
    public dynamic class ModuleVO {
 
        public var 
module_id:Number;
        
public var module_name:String;
 
    }
 
}
 
When the result is 
returned I cast it as an array and insert it into an ArrayCollection for use in 
a datagrid (which works fine). I have two text inputs that I want to be binded 
to the selectedItem in the datagrid. This is where my problems 
occur:
 
<mx:DataGrid 
id="dgModules" dataProvider="{ModelLocator.getInstance().modules}"/>
<view:ModuleEditor module="{dgModules.selectedItem as 
ModuleVO}"/>
 
When the app runs it 
doesn't cast correctly as a ModuleVO and returns null values. I have checked the 
properties of the selectedItem in the DataGrid and it has both module_id and 
module_name but something goes awry in the casting process. I tried adding a 
constructor to the ModuleVO class that accepts an object:
 
package 
com.xxx.xxx.model {
 
    
[Bindable]
    public dynamic class ModuleVO {
 
        public var 
module_id:Number;
        
public var module_name:String;
 
        public function 
ModuleVO(module:Object) {
            
this.module_id = module.module_id
            
this.module_name = 
module.module_name
        
}
 
    }
 
}
 
and changing the 
Module Editor code to:
 

<mx:DataGrid 
id="dgModules" dataProvider="{ModelLocator.getInstance().modules}"/>
<view:ModuleEditor module="{new 
ModuleVO(dgModules.selectedItem)}"/>
 
and it works fine. This method seems like it 
requires unneccessary lines of code and makes adding further properties a pain 
in the neck. Can anyone shed any light on where I am going wrong?
 
Thanks in advance,
 
Pete
