I’m using the Employee Activities Application template (http://www.microsoft.com/downloads/en/details.aspx?FamilyId=1029807F-FD44-4704-936F-BD19A6455351&displaylang=en) and am trying to customize the Activities list to reflect two different content types. There are fields already in the Activities list I would like to include in both my other two content types. These Actitivies fields must be hidden, since I cannot find them in the site column list or select to add them to my two content types. The Activities list is based on what appears to be a hidden content type also named “Event,” with the normal Event site content type as it’s parent. I have already unhidden the parent Event type. When I go to edit the (sub) Event content type, only Name and Description appears in the options to edit under Settings, there is no link for group. I can see the ctype number in the url but when I try to remove the list number from the url to reflect your example above I just get a page that says “Error.” Any assistance or suggestions would be appreciated, thank you!

I made the mistake of renaming a couple of OOB/_Hidden site columns too (Title, Comment). A little hunting provides some relief/fixes:

Not sure if renaming to the correct/original name and selecting custom group “_Hidden” works for site columns (or content types). Need to test/verify that and the above “solutions” in non-production (when I can get access).

Not being a (decent) coder I would imagine the info on msdn (”http://msdn.microsoft.com/en-us/library/microsoft.sharepoint.spfield.group.aspx”) could be used to enumerate what’s in the _Hidden group.

BTW, everywhere I’ve looked emphatically recommends: leave OOB/_Hidden objects alone. Use them as they are or as Paul has done, create your own if the need is there.

Again, I advise against customizing the OOB fields. End Date (internal name _EndDate) and End Time (internal name EndDate) are both valid and come OOB. EndDate is used on Event, I’m not sure about the other one.

If it has the same internal name (FieldID) then it’s the same field. If you change that in one place (really not recommended for OOB fields) it will change EVERYWHERE if changed at the Site Column level. You should be able to change names or hidden/required at the List level.
