Question

in flashbuilder debugger mode, I can examine all the props/vals of the FacebookSession object returned by FacebookDesktop.login when I place a breakpoint in my loginhandler method.

however, I cannot seem to iterate through the FacebookSession object using for…in. I have checked to see if the FacebookSession is dynamic using ObjectUtil.isDynamicObject(…), but it is not, so a for..in should work.

public function gf_handle_facebook_login_return( argl_success : Object ,
                                                 argl_failure : Object  ) : void 
  { // IF I ADD breakpoint here, I get a fully populated argl_success object in flashbuilder's Debugger Variables tab.

    trace( "gf_handle_facebook_login_return , A : " + typeof( argl_success ) + " , " + argl_success[ "uid" ] ) ; // works
    trace( "gf_handle_facebook_login_return , C : " + ObjectUtil.isDynamicObject( argl_success ) ) ; // false ... is NOT a dynamic class

    var lvo_FBS : FacebookSession = FacebookSession ( argl_success ) ; // tried it with and without casting
    var lvn_prop :* ;
    for ( lvn_prop  in lvo_FBS) 
      { trace( "gf_handle_facebook_login_return , D : " + lvn_prop   ) ; // is never called
      }
    for each( lvn_prop   in lvo_FBS) 
      { trace( "gf_handle_facebook_login_return , E : " + lvn_prop   ) ; // is never called
      }
  }

For in will only loop through dynamic properties and as you said it is not a dynamic.

Try this example

//Get an XML description of this class
//and return the variable types as XMLList with e4x
var varList:XMLList = flash.utils.describeType(myVO)..variable;

for(var i:int; i < varList.length(); i++){
//Show the name and the value
trace(varList[i].@name+':'+ myVO[varList[i].@name]);
}
