 Hi,
 
 My flex application is hosted on a public-ip machine and it is accessing the 
 webservice hosted on a Jboss server on another public-ip machine. The 
 crossdomain.xml file is placed at the root of the server and looks as shown 
 below
 
   ?xml version=1.0 ? 
   !DOCTYPE cross-domain-policy (View Source for full doctype...) 
  cross-domain-policy
   site-control permitted-cross-domain-policies=master-only / 
   allow-access-from domain=* secure=true / 
   allow-http-request-headers-from domain=* headers=* secure=true / 
   /cross-domain-policy
 
 I am able to access and load the swf file in the same domain. But when I 
 access the swf from a different domain, I am getting 'Security Error' and the 
 webservice call fails inspite of having the crossdomain file on the server.
 
 Any pointers in this regard would be greatly appreciated. I am stuck with 
 problem from past 1 week and need to get this working at the earliest.
 
 Thanks in advance,
 Akila

[flexcoders] Re: Need help Combobox label property

[vin.flex]

Hi there,

You can use the following code:

?xml version=1.0 encoding=utf-8?
mx:ComboBox xmlns:mx=http://www.adobe.com/2006/mxml;
   mx:Script
  ![CDATA[
 private var _selectedValue:String;
 private var bSelectedValueSet:Boolean = false;
 private var bDataProviderSet:Boolean = false;

 // Override committ, this may be called repeatedly 
 override protected function commitProperties():void
 {
// invoke ComboBox version 
super.commitProperties();

// If value set and have dataProvider 
if (bSelectedValueSet  bDataProviderSet)
{
   // Set flag to false so code won't be called until selectedValue 
is set again 
   bSelectedValueSet=false;
   // Loop through dataProvider 
   for (var i:int=0;ithis.dataProvider.length;i++)
   {
  // Get this item's data 
  var item:String = this.dataProvider[i].FIELDNAME;
   
  // Check if is selectedValue 
  if(item == _selectedValue)
  {
 // Yes, set selectedIndex 
 this.selectedIndex = i;
 break;
  }
   }
}
 }

 // Trap dataProvider being set 
 override public function set dataProvider(o:Object):void
 {
// invoke ComboBox version 
super.dataProvider = o;

// This may get called before dataProvider is set, so make sure not 
null and has entries 
if (o!=null  o.length)
{
   // Got it, set flag 
   bDataProviderSet = true;
} else
   bDataProviderSet = false;
 }

 // set for selectedValue 
 public function set selectedValue(s:String):void
 {
// Set flag 
bSelectedValueSet = true;
// Save value 
_selectedValue = s;
// Invalidate to force commit 
invalidateProperties();
 }
  ]]
   /mx:Script

/mx:ComboBox



create this as a reusable component and use this instead of regular 
combobox:

1) Make sure to replace FIELDNAME in the above code with the name of the 
field in the dataprovider.

2) Instead of selectedindex use comboboxId.selectedValue = Value you want to 
ser.

this will solve your problem.
