Encountered a strange case. The customer has a document library, and in that library a lookup column with multiple values. The column is called Tematikk.
Here's the strange part: When the users create new documents, and select one or more values in the lookup column, it gets saved to the item. But when editing the properties on an existing document and selecting one or more values in the lookup column (see screenshot below), no values in this column gets saved back to the item. Other columns values are saved as expected.
After the user clicks Save in the properties form, the lookup column is still empty. The version number has incremented as expected (1.5), so a new minor version of the document has been saved:
This is a SharePoint Server 2013 farm, and was updated with the latest CU today. But still no difference.
Has anyone any clue on what might be going on here?
Thanks for any help and input!
Edit:
Here's the SchemaXml of the column from the two document libraries.
