Re: Saving using form zone

[George Christman]

Well the only reason I'm using a Zone update on the form is because I need to
save new addrow data contained within a popup box to the user session and
then reload the form with select menus containing the addrow data.  When I
use to submit the request without using the zone update, the page would just
reloaded using the update page, it would set the page scroll to the top of
the page rather than just staying static when the popup box closed out. That
destroyed the UX completely. 

The Zone update resolves the UX, however comes with the above side effects.

The code. 

Create.class
 
    @Property
    private boolean newObject;
    
    void onActivate() {
        newObject = true;
    }

Component.class

    @SessionState
    private ObjectState objectState;

    @Parameter
    private boolean newObject;

    private boolean newObjectUpdate;

    void onPrepareForRender() {
        if(newObject  && !newObjectUpdate) {
            objectState.setObject(new Object());
        }
   }

   @OnEvent(value = EventConstants.SELECTED, component = "update")
   Object updateObjectRequest() {

        objectState.setObject(getObject());  
        newObjectUpdate = true;

        return formZone.getBody();
   }

   @CommitAfter
   @OnEvent(value = EventConstants.SELECTED, component = "commit")
   Object commitObjectRequest() {
        Session newSession =
sessionSource.getSessionFactory().openSession();
        Transaction tx = null;

        try {
            tx = newSession.beginTransaction();

            newSession.saveOrUpdate(getObject());
            update.setObject(getObject());

            tx.commit();
        } catch (Exception e) {
            if (tx != null) {
                tx.rollback();
            }
            throw e;
        } finally {
            newSession.close();
        }
        return update;
   }

    public Object getObject() {
        return objectState.getObject();
    }


Update.class

    public void setObject(Object object) {
        this.object= object;
    }   

    Class<?> onActivate(Object object) {
        if(object!= null) {
            this.object= object;
        } else {
            return Index.class;
        }
        return null;
    }

    Object onPassivate() {
        Object value = null;
        if (object != null) {
                value = object.getId();
        }
        return value;
    } 

    void setupRender() {
        if((objectState.getObject() == null) || (object  != null && !object
.getId().equals(objectState.getObjectt().getId()))) {
            objectState.setObject(object);
        }
    }
