Alfresco-Share l\u00e4sst im Standard den Download von Objekten zu, sobald Leserechte vorhanden sind. Das macht grunds\u00e4tzlich so auch Sinn. Es kann aber doch sein, dass man unter gewissen Umst\u00e4nden den Download „verhindern“ will, auch wenn der lesende Zugriff gestattet ist. Die hier beschriebene Methode verhindert den Download nicht per se in Alfresco (CIFS, etc.). Ich beschr\u00e4nke mich auf Alfresco-Share und begn\u00fcge mich auch damit, dass der Download-Button einfach nicht angezeigt wird. H\u00f6chstwahrscheinlich gibt es noch elegantere M\u00f6gichkeiten um dies in Alfresco zu bewerkstelligen. Die beschriebene L\u00f6sung gewinnt also bestimmt keinen „Sch\u00f6nheitspreis“. F\u00fcr meine Belange reicht’s aber aus:<\/p>\n

Die Aktionen sind nicht der einzige Weg um ein Dokument herunterladen zu k\u00f6nnen. Auf der Dokumenten-Detail Ansicht gibt es auch noch einen grossen Download-Button, der weg muss:<\/p>\n
