Issue when number of fields grows past amount

Oct 3, 2014 at 1:14 PM
I have a form which has 36 fields/columns in list. When I attempt to try and add a user or group, nothing happens. When I attempt to select Ok or Cancel, a generic error is displayed.
Have you attempted to use more than 40 fields using this control?

This is when using SharePoint 2010.

I never test it in a list with more than 40 fields.
in your enviroment, if fields count is less than 40, is it ok?
