I recently ran into an issue after updating MIM 2016 to version where I was unable to select workflows when creating an MPR.  The error displayed was The Required Field Cannot Be Empty. The Selected workflow would be cleared when hitting next or submit button.



Further testing identified that you could successfully add workflows from the first page of the paginated list of workflows, but not from subsequent pages of the paginated list of workflows.


MIM Release documentation:




Windows Server 2012 R2

SharePoint Foundation 2013

SQL Client 2012

SQL Server 2016

.Net 4.6 (KB3045563)



The resolution to the issue was to uninstall .Net 4.6 (KB3045563) after applying the MIM patch which allowed workflows to be selected and successfully saved to the MPR from all pages of the paginated workflow list.
