SharePoint 2013 July 2014 CU - People Picker fields empty in Edit forms

Question

After applying the July 2014 CU for SharePoint server, I discovered that Person or Group (People Picker) fields are not populated with server values in list item Edit forms.  However, the field values can be viewed in list views
and in Display forms.  I examined the client side code and determined that field data is not being returned from the server for Edit forms. 
In a test environment, I uninstalled SharePoint 2013, reinstalled SP 2013 with SP1 and the issue went away.  I then applied the May 2014, June 2014, and July 2014 CUs.  The issue did not exist after applying the May and June CUs.  It
did exist after applying the July 2014 CU.

Answer 1

There is a workaround for this issue.  It's a little convoluted, but hey, it's SharePoint.  First, you must have a list that has at least one entry in it.
 To begin with, you must first
have a list with at least one item in the list.
Next you edit the item with a role that has at least Design privilege, but don't save your changes.
Instead you Edit the page so you can then edit that web part.  You can edit the page by clicking on the cog icon and selecting Edit Page
Edit the web part itself
Under “Miscellaneous” section on the just exposed web part window, select "Server Render (Server Render)" in the drop down labeled “CSR Render Mode
Click on “Apply” button within the web part
Save
I was told also the Sept CU would fix the issue but it is under review and to wait until the first of October.  Incidentally we found that if you put the entire list into Quick Edit mode, the issue does
not appear.
I hope this helps someone.
