We have an Infopath custom form published in a SharePoint library (as content type). This form has a repeating table with a few columns. The idea is, one department adds "issues" in the repeating table and the other department users mark those issue as "Resolved" etc once completed.
The repeating table data is not saved anywhere else (not promoted as a sharepoint field or even saved in another SP list) except in the actual XML files. This was working up until 10 days ago.
Now when department1's user submits these "issues" it sometimes saves them all, sometimes a few and other times none. By the time department2's user opens the form up, nothing is shown and even opening up the XML for the forms saved shows missing data. The form always opens up in browser so a clients installation for infopath is not used.
I have no idea where to even get a pinpoint for this issue. I have tried checking the network to see if its a network issue or IIS. Nothing.
Any help would be greatly appreciated!
