Remove content not working

ShrutiA

I have a simple DFC session trying to delete one of the content object in dmr_content. But nothing happens. Pl see code below

IDfSysObject obj = (IDfSysObject)

sess.getObject(new DfId(r_object_id));

obj.removeContent(0);

Did you execute save?

obj.removeContent(0);

obj.save();
