      Description

      I have simple model:
      class Book {
      @ManyToMany //unidirectional
      private List<DictionaryEntry> dictionaryEntryList;
      }

      In the JSF it is presented as:
      <h:selectManyListbox id="select2Status" value="#

      {bookHome.instance.dictionaryEntryList}

      " required="false">
      <s:convertEntity />
      <s:selectItems value="#

      {dictionaryEntryList.resultList}

      " var="item" label="#

      {item.value}

      " noSelectionLabel="---------" />
      </h:selectManyListbox>

      1. When I create entity with some elements selected everything works fine.
      2. When I edit the selection and update everything works great.
      3. The problem occurs when I deselect all the items and try to do an update. I get then:
