> If you inject a UIComponent into a bean as follows:
>  @In(required = false, value = "#{uiComponent['XXX']}")
> It fails for any method call that occurs on the bean at a time when the component is unavailable under the ViewRoot.
> An IllegalArgumentException is thrown by the Sun RI from UIComponentBase:588 if findComponent(id) is unsuccessful, whereas MyFaces simply returns null.  This can be fixed by patching org.jboss.seam.faces.UIComponent to catch the IllegalArgumentException and return null.
> We were working around this by avoiding using @In for this and looking under the FacesContext.ViewRoot manually, but eventually decided to patch Seam ourselves until this issue is fixed in CVS.  The above fix is working well for us.
