Re: Watermarking documents on edit offline click in Alfresco https://connect.hyland.com/t5/alfresco-forum/watermarking-documents-on-edit-offline-click-in-alfresco/m-p/83581#M25573 <P>What do you intend by this line:</P> <P><CODE>myNoderef = new NodeRef("workspace","SpacesStore",req.getContent().getContent());</CODE></P> <P>It looks like you want to create an instance of a NodeRef, but the constructor expects an ID, not content.</P> Thu, 19 Sep 2019 13:53:03 GMT https://connect.hyland.com/t5/alfresco-forum/watermarking-documents-on-edit-offline-click-in-alfresco/m-p/83581#M25573 jpotts
