Probleme mit UrlFactory nach Update auf FirstSpirit 5.2

Gibt es eine Möglichkeit das Problem - zumindest temporär - relativ einfach zu lösen, damit die Generierung mit den passenden URLs zumindest mal durchläuft.
Besten Dank und viele Grüße

Hallo zusammen,
genau das gleiche Problem tritt auch bei mir nach einem Update auf.(Server-Version: 5.2.311.72449 )

...
Zusätzliche Info: Bei Seiten, die bereits vor dem update bestanden tritt der Fehler nicht auf, weil da wohl ja auch die URL gespeichert ist und deswegen auch nicht neu berechnet werden muss. Sobald man aber über Extras -> URL zurücksetzen diese Löscht kommt der o.g. Fehler auch bei diesen Seiten.
Wäre für eine schnelle Hilfe dankbar!

Alex

Hallo Daniel,
vom FirstSpirit Support, hab es einen Hinweis, dass die lookupPath() methode nur noch mit Ordnern arbeitet. Wenn man hier also eine PageRefImpl übergibt gibt es einen fehler.
Bei mir hat jetzt ein kleiner Fix bereits ausgereicht. Schau mal ob das für dich in Frage kommt:
Einfach
_pathLookup.lookupPath(contentProducer.getParent(), language, templateSet);
statt
_pathLookup.lookupPath(contentProducer, language, templateSet);
Grüße,
Alex

Hi Alex,
danke für den Hinweis. Ich hatte auch vom Support den Hinweis erhalten und auch einen Fix bei uns in der Klasse eingebaut, so dass es wieder funktioniert.
Ich habe allerdings abgefragt von welchem Typ das Objekt ist...
if (contentProducer instanceof MediaFolder || contentProducer instanceof SiteStoreFolder) {
path = _pathLookup.lookupPath(contentProducer, language, templateSet);
}
Funtioniert bei uns.
Viele Grüße
Daniel
