    Richfaces 4 M6: second click in sortable header don´t work

    Flávio Henrique Newbie

      I followed the showcase and now I am able to sort, BUT if I click twice, only the first click is processed. I also find a strange behavior. There are many calls to action="#{meuMB.sortByNome}" when the column header is clicked. I didn´t understand why this method must be void, since JSF action method allways return a String. By the way, I also tried to change this but the problem still occurs. This problem affected all browsers.

       

      ManagedBean code related to sorting:

       

      (...)

      private SortOrder nomeOrder = SortOrder.unsorted;

       

          public void sortByNome(){

               if (this.nomeOrder.equals(SortOrder.ascending)) {

                this.nomeOrder = SortOrder.descending;

               } else {

                   this.nomeOrder = SortOrder.ascending;

               }

          }
