| | | - validation & selectManyListbox | - validation & selectManyListbox 2007-08-09 - By dschaedl
Back
JBoss 4.0.5
JBoss Seam 1.2.1.GA
My h:selectManyListbox displays my list correctly. But when I select entries
and hit update to update my model containing this list I get a validation Error
: "value is not valid" (on the webpage). How are the entries validated? why isn
't it valid?
If I switch off the validation and press the update-button nothing happens
(Jboss is doing 'someting', but no logging, no page-forwarding; the update
-action seems not to be called)
The update works just fine if I deselect all entries in the listbox.
The XHTML:
| ...
| <s:decorate id="coursesDecoration" template="layout/edit.xhtml">
| <ui:define name="label">alle PRC-Kurse</ui:define>
| <h:selectManyListbox value="#{trainer.courses}" >
| <s:selectItems value="#{courseLister.allCourses}" var="course" label="#
{course.name}" />
| <s:convertEntity/>
| </h:selectManyListbox>
| </s:decorate>
| ...
| <h:commandButton id="updatetrainer" value="update" action="#{edittrainer
.updateTrainer}" rendered="#{!edittrainer.newTrainer}" />

Trainer

| @(protected)
| public List<Course> getCourses() {

| public void setCourses(List<Course> courses) {
| this.courses = courses;
| }
| ...
|
Course
| @(protected)
| @(protected)("course")
| public class Course implements Serializable{
|
| @(protected)(mappedBy="courses")
| private List<Trainer> trainers;
| ...
|
CourseListerBean
| ...
| public List<Course> getAllCourses() {
| return em.createQuery("from Course c order by c.name desc")
.getResultList();
| }
| ...
|
editTrainerBean
| @(protected)
| @(protected)("edittrainer")
| public class EditTrainerBean implements EditTrainer {
|
| @(protected)(required=false)
| @(protected)
| private Trainer trainer;
|
| public void updateTrainer() {
| log.info("updating trainer: #{trainer.name} id:#{trainer.id}"); <--
never shown!
| em.persist(trainer);
| }
| ...
|
any ideas?
