Hi,
I am trying to implement some DocumentSet EditForm with Drag and Drop functionality on O365 with Javascript only.
Here is what I want to do: I have added the DocumentSet Folder WebPart to the DocumentSet EditForm and supplied the correct Url parameters to make the DocumentSet WebPart show the correct folder. So far so good.
When I now open this EditForm and type some information into the columns and drag and drop a file in the DocumentSet WebPart and hit the Save button I get the famous 'Sorry something went wrong' error message (File <docSetName> has been modified by<userId> at <someDateTime>). Without dragging and dropping it works as expected.
I think this happens, because of some version conflict handling stuff is detecting that the 'item/folder' has been modified since the EditForm has been initially called. A refresh would solve the problem, but cannot be done because the data entered in the columns will not be saved. How can I tell the Form to submit the data anyway? Or How can I overcome this conflict detection?
