After contacting Nintex Support, it appears these are known issue but not being addressed as bugs. They occur in the latest version of Nintex Forms for SharePoint 2013 on-prem (18.104.22.168) as of Apr, 6, 2016.
When updating a list item using PowerShell, list items disappear on Nintex forms. To replicate:
When adding a Nintex form to an existing list populated with items that include attachments, the attachments are not displayed on the Nintex form. To replicate:
Anyone have a workaround for these issues?
Solved! Go to Solution.
Nintex workflow approach (the example uses approval form but you should be able to do it with initial form as well. It also requires a bit of jQuery format the attachments before displaying on the form)
I am having the same issue with Nintex Forms 2010 v22.214.171.124 and am surprised it is not being treated as a bug. Frank Field does this sound right to you?
Thanks in advance,
I am having issues with missing attachments on Nintex Forms? I am not sure if this is the same?I am using Nintex Forms 2010 v1.7
Scenario on our development Environment
Upload the form to the list with attachment
However when the form is submitted the attachment was not present
Is this the same problem?
I'm not sure. I don't know what you mean when you say you "Upload the form". I'm not familiar with that. Can you send a screens shot?
I'm just seeing this. Are the attachments disappearing completely meaning they are not being added to the list item or is the view of the attachments missing?
Again being slightly new to the issue, are you able to retract and add back the attachment control to the form? Does that bring the linkage back?
Also from PowerShell are you able to see the attachments on the list item?
Trying to figure out what may be going on here.
Have you tried going into the Nintex form and setting the Attachments control settings default control to yes?
We had a similar issue and this resolved it for us.
In my case, I'm adding the attachment in a workflow and can see the attachment in PowerShell or if I delete the Nintex form I will see it on the default SharePoint form attachments. If I had to guess, Nintex is putting the list of attachments in formdata or something like that behind the scenes. That is why it is not showing up when attachments are added programattically. You can easily repro by creating a new list, add an item with an attachment and then create a Nintex form for the list. If you open up the previously created item, it will not be displayed.
