Issue: Multiple Item Versions are created when a list item is created/updated with attachments via Crow Canyon NITRO Forms or Portal

If you are facing this issue then please follow below steps:

– Upgrade to latest Portal solution (if items are created from Portal), Upgrade to latest NITRO forms solution (if items are being added using NITRO forms). Please contact Crow Canyon support for latest solutions and upgrade instructions

Crow Canyon CommonUtils solution installs a feature ‘Crow Canyon Forms Attachments’ in the site:

– Activate this feature in all sites where you are using ‘NITRO Forms’ and all the sites used in portal (not required on the actual portal site).


Troubleshooting steps

Go to ‘Site Assets’ of the site and make sure group ‘Everyone’ has ‘Edit’ level permissions on the folder ‘CCSItemAttachments’ in ‘Site Assets’.
