We are using SharePoint 2016 on premises and FormsViewer. SubmitToSharePointList command successfully creates and updates list items, but we have problem when trying to add attachment to the same list.

Here is the command used: SubmitToSharePointList /submit=ShPList /mapping=FilmAttachment /dsname=AddAttachment
All parameters and are correct. The corresponding list item is updated by this command, as I can see a new version added in version history without any change.

Attachment field of that list item stays blank.

Hi, Arthur - I'm sorry for the inconvenience - I've taken a look at the code and I don't think this is currently implemented in FormsViewer. One option might be to use SaveToSharePoint to save your attachments to a library and then include a link to them in your list item.... would that work for you?

Thank you for the explanation, Hilary!

I checked everything several times and didn't suspect that it's not supported. Will try to find some workaround for this.

By the way, do you have any plans to implement it in the future? 

I'm going to open a case on it, so we at least have it on our radar. Decisions on implementation of features are not mine to make, but this will at least get it on the radar. :)
