Hello I want to select an object from a Datatable via the DataModel and the
DataModelSelectionIndex like in the booking example.
I always get an Exception :
....attempted to bind an Out attribute of the wrong type to: contributable...
My Class looks like this
| @Stateful
| @Name("findContributables")
| @Interceptor(SeamInterceptor.class)
| public class FindContributablesAction implements FindContributables,
Serializable
| {
|
|
| private static final long serialVersionUID = -6803933802941651662L;
|
|
|
| @PersistenceContext(type=EXTENDED)
| private EntityManager em;
|
| @DataModel
| private List<Object> contributables;
| @DataModelSelectionIndex
| private int contributableIndex;
|
| @Out
| private Object contributable;
| ....
|
|
and the method invoked in the Datatable is selectContributable()
| public String selectContributable()
| {
| if (contributables==null) return "contributableList";
| try{
| setContributable();
| }catch(Exception
e){System.out.println(e+"@selectContributable");}
| System.out.println("Contributable was selected
@setContributable");
| return "contributableSelected";
| }
|
| private void setContributable(){
| try{
| contributable = contributables.get(contributableIndex);
| }catch(Exception
e){System.out.println(e.toString()+"@setContributable");}
| System.out.println("Contributable #"+contributableIndex+" was set
@setContributable" +contributable.toString());
| }
|
The DataTable is generated by this method in the same class
The EntityManger return here a List of several Object form the type Journal ect.
| public List<Object> getAllContributables() {
| String[] types = {"Journal", "Book", "Workshop", "Conference"};
| List<Object> list = null;
| try {
| ContributableManager cm = new
ContributableManagerBean(em);
| for (int i=0; i<types.length; i++) {
| List<Object> templist =
cm.findContributable(types, null);
| if (list == null) {
| list = templist;
| }
| else {
| list.addAll(templist);
| }
| }
| }
| catch (Exception e) {
| }
| contributables = list;
| return list;
| }
|
