Hallo zusammen,

Ich versuche gerade einen ValueService zu schreiben, der Service soll sowohl für SiteArchitect als auch für den ContentCreator funktioniert.

Ich versuche auf die page.getId() zurückzugreifen.

private String findPageId(final SpecialistsBroker broker){
  WebeditUiAgent uiWebEditAgent = broker.requestSpecialist(WebeditUiAgent.TYPE);
  if (uiWebEditAgent == null) {
  UIStoreAgent uiStoreAgent = broker.requestSpecialist(UIStoreAgent.TYPE);
   Logging.logInfo("access over the site architect " , logger);
   GuiStoreElement activeUiElement = uiStoreAgent.getActiveUiElement();
  return Long.toString(activeUiElement.getId());
   } else if (uiWebEditAgent != null){
  Logging.logInfo("access over the content creator " , logger);
  return Long.toString(uiWebEditAgent.getPreviewElement().getId());
   }
  Logging.logWarning("page id is empty!" , logger);
  return null;
}

so kann nicht funktionieren, da der UIStoreAgent nicht teil der offiziellen API ist.

Nun habe ich das ganze mit dem ModelListener implementiert ohne viele Erfolg

private String findPageId(final SpecialistsBroker broker){
     WebeditUiAgent uiWebEditAgent = broker.requestSpecialist(WebeditUiAgent.TYPE);
        if (uiWebEditAgent == null) {
            Logging.logInfo("access over the site architect" , logger);
            PageModelListener  pageModelListener = new PageModelListener();
            ServicesBroker servicesBroker = broker.requireSpecialist(ServicesBroker.TYPE);
            servicesBroker.getService(ModelService.class).addModelListener(SelectionModel.EDITORIAL, pageModelListener);
            return  Long.toString(pageModelListener.getCurrentPagePageId());
        } else if (uiWebEditAgent != null){
            Logging.logInfo("access over the content creator " , logger);
            return Long.toString(uiWebEditAgent.getPreviewElement().getId());
        }
        Logging.logWarning("page id is empty!" , logger);
        return null;
    }
public class PageModelListener  implements ModelListener {
    private Object currentObject;
    @Override
    public void modelChanged(Object o) {
        currentObject = o;
    }
    public long getCurrentPagePageId(){
        long longValue = 0L;
        if(currentObject != null) {
            IDProvider elementWrapper = ((SelectionModel) currentObject).getElement();
            if (elementWrapper instanceof Page){
                longValue = elementWrapper.getId();
            }
        }
        return longValue;
    }
}

und bekomme folgende Exception:
