3:08 a.m.
My question is 'why this app work with pur Seam and MyFaces, but not with
ICEFaces'
1. Abstract editor class
public abstract class AbstractEditorBean<T extends StandardEntity> extends
AbstractEditorListeGemeinsames<T> implements Serializable {
| .
| .
| protected boolean neu;
|
| @Begin(nested=true, ifOutcome={"editor"})
| public String bearbeiten() {
|
| if (id == null) {
| addWarning(idError());
| return "main";
| }
|
| //Entity holen
| try {
| setEntity((T) em.find(getEntityClass(), Long.parseLong(id)));
| neu = false;
| if (getEntity() == null) throw new Exception();
| } catch (Exception ex) {
| addWarning(findenError());
| return null;
| }
|
| nachLaden();
|
| //Alles ok? Dann Editor anzeigen
| return "editor";
| }
| .
| .
| public boolean getNeu() {
| checkKorrekterAufruf();
| return neu;
| }
| .
| .
| }
|
2. Measurement class
@Stateful
| @Scope(ScopeType.CONVERSATION)
| @Name("messmitteltypEditor")
| @TransactionAttribute(TransactionAttributeType.NOT_SUPPORTED)
| public class MessmitteltypEditorBean extends AbstractEditorBean<Messmitteltyp>
implements MessmitteltypEditor {
|
| @In(required=false) @Out(required=false)
| private Messmitteltyp messmitteltyp;
| .
| .
| }
3. All changes to web.xml, faces-config.xml and lib dirs for ICEFaces as descriped
here:http://support.icesoft.com/jive/servlet/KbServlet/download/623-102-8...
4. The xhtml pages:

Here the steps when I debug this app
1. current page: messketteListe.xhtml - click: bearbeiten
2. methode invoked: AbstractEditor.bearbeiten() -> set property neu=true ->
outcome:"editor"
3. from outcome:"editor" -> messmitteltypEditor.xhtml
4. BANG. java.lang.NullPointerException (Exception getting value of property neu of base
of type
So whats going wrong here? Without ICEFaces the app working perfectly. In ICEFaces Forum
they gave no advice.
Thanks
Andreas Franke
