I've built a rollup of a list that works great up until include a field called "Project Resources" which is a People/Group field that allows multiple selections. When I add that FieldRef to my ViewFields list the output goes from 4 rolled up items (which
is correct) to 0 items. Each list has at least one person in the resources field.
It doesn't matter what form the select command is in (<FieldRef Name="Project_x0020_Resources"/> or <FieldRef Name='Project_x0020_Resources'/> ) that field seems to break the rollup.
