I am displaying a list of entities (Student) with a @DataModel on a JSF Page
with two links: one for editing and one for delting. For some reason the
injection by DataModelSelection does not work correctly. My my status-EL
messages for these two functions aren't shown correctly. Deletin entities works
(except for the status message) whereas editing does not.
This is my SFSB:
| @Stateful
| @Scope(ScopeType.SESSION)
| @Name("inscription")
| public class InscriptionAction implements InscriptionFacade {
|
| @Logger private Log log;
| @PersistenceContext(type=PersistenceContextType.EXTENDED) private
EntityManager em;
| @DataModel private List<Student> studentList;
|
| @In(required=false)
| @Out(required=false)
| @DataModelSelection
| private StudentInsc inscribben; // StudentInsc inherits Student
|
| public String delete() {
| //
| // This log shows only "Deleting inscribben student"
| //
| log.info("Deleting inscribben student #{inscribben.givenName}
#{inscribben.familyName}");
| studentList.remove(inscribben);
| StudentInsc stud = em.merge(inscribben);
| em.remove(stud);
|
| return "insc";
| }
|
| public String startEdit() {
| //
| // This log shows only "Start editing"
| //
| log.info("Start editing #{inscribben.givenName}
#{inscribben.familyName}");
| em.merge(inscribben);
| return "editInsc";
| }
|
| public String finishEdit() {
| //
| // This log shows the correct values from the form "Finish editing Newname
Newfamilyname"
| // but doesn't merge the inscribben student to the database
| //
| log.info("Finish editing #{inscribben.givenName}
#{inscribben.familyName}");
|
| em.merge(inscribben);
| return "insc";
| }
|
| [....]
|
This is my table:
|
| <rich:dataTable value="#{studentList}" var="stud"
rendered="#{studentList.rowCount>0}" >
| [....]
|
| <rich:column><s:link action="#{inscription.startEdit}"
value="#{stud.givenName} #{stud.familyName}" /></rich:column>
| <rich:column><s:link action="#{inscription.delete}" value="delete"
/></rich:column>
|
| [....]
| </rich:dataTable>
|
|
startEdit redirects to a form, where new values can be entered. On a button
click finishEdit is invoked and the DataTable is shown again.
I've already tried a lot, but nothing worked. Can somebody please help me?
