Troubleshooting

Further debugging in the SP ULS logs and we found some strange facts which are based on event receivers

  • SPSolutionExporter: Microsoft.SharePoint.SPException: Feature definition with Id 77658379-50ff-4e1e-a431-5652bee07a87 failed validation
  • Looking for 'ReceiverAssembly' attribute in manifest root node for solution
  • Looking for 'ReceiverClass' attribute in manifest root node for solution
  • The 'Format' attribute is invalid - The value 'CheckBoxes' is invalid according to its datatype
  • Debug further to find out where the problem is.
  • Downloaded the saved wsp's from  /_catalogs/solutions/Forms/AllItems.aspx to my desktop
  • Renamed it to .cab
  • Extracted all the contents and found some interesting facts along with manifest.xml file like-
  • List Instances
  • Modules
  • Property bags
  • web template

Inside List Instances, we found ElementsFields.xml

Once we opened the above xml file, search for the checkboxes and found the following-

Further exploration on this, it seems that the checkbox attribute is invalid and needs to be modified.

Resolution

After this one, the solution is pretty much simple, just go ahead and remove that affected column / remove the affected content type – does not require IISRESET also.
