   Hi
   
   I never used that approach since it couples files and is bad design. I recommend you to comunicate via composition and events.
   
   Anyway, I looked for your problems and I think you need the following bead:
   
   ```/**
        *  The ParentDocumentBead class looks up the parent
        *  chain to find a parent that was written in MXML.
        *  Because it is usually rare for an application
        *  to need to know this information, an optional bead
        *  is used to compute it, instead of baking in the
        *  overhead of a recursive infrastucture to store
        *  this information.  It is intended to be used
        *  as a bead in the top-level tag of an MXML document.
        *  
        *  @royaleignoreimport org.apache.royale.core.IChild
        * 
        *  @langversion 3.0
        *  @playerversion Flash 10.2
        *  @playerversion AIR 2.6
        *  @productversion Royale 0.0
        */
   	public class ParentDocumentBead extends DispatcherBead
   ```
   
   Also we have `parent` in each component but I think you want the previous bead to refer to the parent MXML file.
