Hi, We have a custom list in MOSS 2007, which has workflow that are set to start mnually only. Whenever someone tries to edit an item, attach a file and save the item, we get the error that: Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code. Exception Details: Microsoft.SharePoint.SPException: Save Conflict Your changes conflict with those made concurrently by another user. If you want your changes to be applied, click Back in your Web browser, refresh the page, and resubmit your changes. Source Error: An unhandled exception was generated during the execution of the current web request. Information regarding the origin and location of the exception can be identified using the exception stack trace below. Stack Trace: [SPException: Save Conflict Your changes conflict with those made concurrently by another user.

Save Conflict Your changes conflict with those made concurrently by another user. If you want your changes to be applied, click Back in your Web browser, refresh the page, and resubmit your changes. The above error appears only when we add an attachment to the list item. We can modify any other fields of this list without getting this error. Can someone help em to resolve this? many thanks, Anu

is there any workflow or calculated column associated with this list ?Regards, Pratik Vyas | SharePoint Consultant |

Hi patrik, Thanks for replying. There are no calculated columns in this list. However, there are workflows which are set to start manually only and these workflows are not active when we update the list item. regards, Anu

Have you added any custom even receivers to the list (or use some third party feature which may have) ?

No, there are no custom event receivers or third party features. regards, Anu
