Hi,Dieter ,I also encountered an issue on classic HCP/Document service. I checked out a document and it's parent type is 'sap:versioned' then I modified the properties and content stream (not empty) then checked in.Very strange the properties has been updated successfully but the content stream is empty! Both the previous content and the new content disappeared without any exceptions .My code is like the snippet blow:
Document doc = checkedOutDocumentByName(openCmisSession, fileName);
...modify properties and content
doc.checkIn(true, properties, contentStream, null);
Is there any limitations in the method 'checkIn'? Any one can help me?
