I’ve setup up two lists.
A main list(list A) and a secondary list(list B).
These two lists are related through lookupfields, where list B looks up items in list A. On the DispForm.aspx for list A, i’ve added a related list(list B) as a viewpart.
When i open an item on list A, it correctly shows the related items in list B.* However, if i open an item on list B and click the lookupfield, the viewpart breaks and gives a correlation error.*
Since i’m on SharePoint online, i’m not able to debug any logs.
My question is therefore, is this intended behavioure or is this a bug? I can see that when clicking on list B, the url for the item on list A is different than what visiting list A directly. It would see that going through list B, SharePoint appends a "rootfolder=%2A" or "rootfolder=*" to the end of the url. Removing the characters after "=" fixes the issue.
*(The images are from a norwegian SharePoint, but it would be the same in any other language i guess, the errormessage on the second image is just the ordinary "cannot show this webpart")
