Flex Type Coercion, I think this is spiritual - believes, COERCION, Flex, this is spiritually, type

I basically have a class:

public class WindowEvent extends Event
{
 public static const WARNEVENT:String = "warnEvent";
 public static const TASKREQEVENT:String = "taskRequestEvent";
 public static const TASKANNOUNCE:String = "taskAnnounce";
 public static const WINDOWCHANGE: String = "windowChange";
 public static const ILLEGALPOSITION:String = "illegalPosition";

 // insert brevity 
}

The first four events work Normal, but I just added ILLEGALPOSITION and tried this:

// inside Window.as
 private function checkDimensions():void {
 if (!Window._legalBoundaryEnable)
 return;
... var pass:Boolean = Window.legalBoundary.containsRect(
455 this.getBounds(stage));
456 if( !pass) {
457 this.dispatchEvent(new WindowEvent(WindowEvent.ILLEGALPOSITION,
... "Illegal Position etc."));
 }
 }

So when I click on the scheduling method , Flex will send me this stack:

TypeError: Error #1034: Type Coercion failed: cannot convert ¬
 flex.utils.ui::WindowEvent@511dce41 to flash.events.MouseEvent.
 at flash.events::EventDispatcher/dispatchEventFunction()
 at flash.events::EventDispatcher/dispatchEvent()
 at mx.core::UIComponent/dispatchEvent () ¬

 at flex.utils.ui::Window/checkDimensions()[C:\Users\~\Window.as: 457]
 at flex.utils.ui::Window/stageResized()[C:\Users\~\Window.as:220]

As you can see from the trace, Window.as : 457 is the last user code line. So WTF is flash.events.EventDispatcher.dispatchEventFunction try to use MouseEvent?

This error usually occurs because the listener you set has incorrect event parameter types . I’m pretty sure this must be the case.

Check all the listeners you set for this event and make sure that the function is

someFunction(event: WindowEvent): void

I basically have a lesson:

public class WindowEvent extends Event
{
 public static const WARNEVENT:String = "warnEvent";
 public static const TASKREQEVENT:String = "taskRequestEvent";
 public static const TASKANNOUNCE:String = "taskAnnounce";
 public static const WINDOWCHANGE:String = "windowChange";
 public static const ILLEGALPOSITION:String = "illegalPosition";

 // insert brevity 
 }

The first four events are working fine, but I just added ILLEGALPOSITION and tried this:

// inside Window.as
 private function checkDimensions():void {
 if(!Window._legalBoundaryEnable)
 return;
... var pass:Boolean = Window.legalBoundary.containsRect(
455 this. getBounds(stage));456 if(!pass) {
457 this.dispatchEvent(new WindowEvent(WindowEvent.ILLEGALPOSITION,
... "Illegal Position etc."));
 }
 }

So when I click on the dispatch method, Flex will send me this stack:

TypeError: Error #1034: Type Coercion failed: cannot convert ¬
flex.utils.ui::WindowEvent@511dce41 to flash.events.MouseEvent.
