public ComponentConfigBuilder addItemInMultifield ( String multifieldLabel , int index , String itemType , String itemLabel , String value ) { String type = String . format ( "multifield#%s#%s" , index , itemType ) ; String label = String . format ( "%s#%s" , multifieldLabel , itemLabel ) ; config . add ( new ConfigurationEntry ( currentTab , type , label , value ) ) ; return this ; }
