Hi , To get the root cause of this issue I suggest you to checklogsandfind out what is going wrong incase of the "Assigned To" column. I suggest you to enable verbose mode of logging and then get the errorsfrom the log files generated to getvaluble information. I hope this will help you out. Thanks, Rahul Rashu
