I am using InfoPath to upload file to SharePoint Library. For that i am using K2 Sharepoint Document Event Wizard. After i upload any documents to share point Document library, i am removing the file attachment from the Infopath form and updating the Sharepoint document Library link. In some cases user might save the InfoPath form temporarily because he/she need more information.
When user open the same form again and try to upload some more attachments, then i am getting error because previous file attachments wont have any valid file names(Remember i just set null to file attachment node).
So i can i hadle empty file attachments in SharePoint Document Event Wizard or is there any other solution handle according to my requirement
