I created two content types based on Document, no extra metadata, called Status Report and Timesheet.
I then created a content type based on the Document Set called Project. Added a couple of site columns of type Person and a managed metadata. I then added Status Report and Timesheet as "Allowed Content Types" in document set settings.
I have created a library and added the Project content type. That all works fine. I can create new projects and assign metadata. Inside the set I can create status reports and timesheets.
My problem is that I want to create a view which will group the documents inside the document set. I don't seem to have "Content type" in the group by drop down.
I am able to add content type to the columns of the view. It displays the correct data but I cannot sort or filter on this column.
Have I done something stupid?
