Hi All, 

I am facing problem when doing checkin after a checkout of "mix:versionable"
node. I am getting following exception at the time of checkin: 
InvalidItemStateException: Unable to perform operation. Session has pending
changes.

org.apache.jackrabbit.webdav.server.AbstractWebdavServlet.doPut(AbstractWebdavServlet.java:566) 

My code is as below: 

            Node fileNode=null; 
            try{ 
            fileNode= node.getNode(ctx.getSystemId()); 
            }catch(PathNotFoundException e){ 
            
            } 
            if(fileNode != null && fileNode.isNodeType("mix:versionable")){ 
            fileNode.checkout(); 
            } 
            if (!config.getIOManager().importContent(ctx, member)) { 
                // any changes should have been reverted in the importer 
                throw new
DavException(DavServletResponse.SC_UNSUPPORTED_MEDIA_TYPE); 
            } 
            // persist changes after successful import 
            if(fileNode != null && fileNode.isNodeType("mix:versionable")){ 
            
            fileNode.checkin(); 
            } 
            Session session=node.getSession(); 
            session.save(); 


I am modifying a files content and if it is versionable node then I am
trying to create a new version but it always says session has pending
changes while I am not performing any changes after checkin. 

Thanks in advance for any help. 

Thanks & Regards 
Shahid K.
