AccessUtil.release in Workflow führt zu Exception

Hallo,

wenn ich die Methode AccessUtil.release in einem Workflow-Skript aufrufe, bekomme ich eine Exception (Code + Exception s.u.).

Ein direktes release auf dem Objekt funktioniert (Code s.u.)

Allerdings möchte ich AccessUtil.release nutzen, um auch abhängige Objekte freigeben zu können.

// Code der funktioniert

context.getStoreElement().release();

// Code der zu Fehler führt

result = de.espirit.firstspirit.access.AccessUtil.release(context.getStoreElement(), false);

context.logInfo(result.getResult());

Aus der Beanshell heraus ist der Aufruf möglich:

result = de.espirit.firstspirit.access.AccessUtil.release(e, false);

result.getResult();

Stacktrace:

Fehler bei der Skriptausführung in Zeile 9.

    Hallo Herr Reinsch,

    auch wenn ich Ihnen gerade bereits über das entsprechende Helpdeskticket geantwortet habe, hier nochmal die Antwort für alle Mitleser :smileywink:

    > Eine Vermutung wäre, dass AccessUtil.release nicht in der gleichen Session wie der Workflow arbeitet.

    Korrekt - AccessUtil arbeitet auf dem Server. Da ein Arbeitsablauf einen Knoten bearbeitet, um ihn weiterschalten zu können, muss bei der Verwendung einer anderen Session der Knoten explizit aus dem Bearbeitungsmodus genommen werden und vor dem Weiterschalten muss der Bearbeitungsmodus wieder gesetzt werden. Ein entsprechendes Beispiel findet sich auch im Demoprojekt, hier der beispielhafte Quellcode für diesen Anwendungsfall:

    storeElement = context.getStoreElement();
     if(storeElement instanceof Page) {
     storeElement.setLock(false, true); 
     recursive = true;
     } else {
     storeElement.setLock(false, false); 
     }
     result = de.espirit.firstspirit.access.AccessUtil.release(storeElement, false);
     context.logInfo(result.getResult());
     storeElement.setLock(true, false);
     context.doTransition("<Name of Transition>");

    Viele Grüsse aus Dortmund,
