A user created a Nintex Form and I am trying to help them trouble shoot. There are fields on the form that are restricted and can only be edited by certain SharePoint groups (Column settings > Appearance > Enabled set to Expression). A new item gets entered by group A and they fill in appropriate information. Group B cannot edit any of those fields, but they have 2 fields they can edit on the form. All other fields are locked down. This part works, but when they try to save the form, one of the other fields clears out and they can't save the form because they don't have the ability to edit it. The field that clears out is an external data column.
Has anyone seen this before? I can't figure out why that field would remove the previously entered data when it gets saved by another user.
are the users in group b able to see/reach the external data? maybe they don't have permissions to read that external data, so when they edit the form, that field cannot store the previous value because for those particular user the value in it isn't valid (they may don't see any valid value)..
you can try it with a new list with just an external column set as the one with the issue..can group b populate it from default sharepoint form? if yes, when you create a nintex forms, is the behaviour the same?
