question: public static UIComponent findChild ( UIComponent parent , String id ) { int sz = parent . getChildCount ( ) ; if ( sz > 0 ) { UIComponent c = null ; List cl = parent . getChildren ( ) ; while ( -- sz >= 0 ) { c = ( UIComponent ) cl . get ( sz ) ; if ( id . equals ( c . getId ( ) ) ) { return c ; } } } return null ; }
target:  A lighter-weight version of UIComponent's findChild.
