Why isn't possible to have ID attribute with a root tag

Question

Hi ,
Why is it not possible to have a id associated with a Root tag ??
Thanks in advance.

Answer 1

CustomClass.mxml
<Canvas id="i_got_a_root_tag_id" >
</Canvas>
Now remember , the id is declared when we declare the class right so even though we don't specify the id in the Application.mxml class , it is a property of the CustomClass.
Main.mxml
<Application>
  <CustomClass />
  <CustomClass />
   <Script>
     public function somethingFunction():void
        i_got_a_root_tag_id.addEventListener(Do.SomethingEvent , handleEvent);
So in the previous example , which instance gets the listener added to it ?  See how root id tags hurt everyone everywhere ?
