I have a job for a client of fixing Infopath forms after a SharePoint migration from 2010 to 2013 In some cases, the forms have been used in quite the complex way: In a Document Library (not a form library) there is a template that is used as an edit item form. After uploading the file with the default SharePoint upload dialogue, the form would open and the user would enter information into the form, which would them define the filed values of the item in the library. This seems to have worked in 2010, but it won't work anymore after migrating to 2013. When I try to upload a file, the form attempts to open, but is then giving an error. The error says it couldn't open the form since it lacks the field "Name" of field type "File". Since that field type is not supported in the Infopath designer, it is impossible to fix this problem through conventional methods.
So I am looking for a way to circumvent this issue. I'm aware I might have to recreate the form and change the workflow, but I hope there might be a different solution.
Thank you for your help.
