Im running OP 4.2.7. Now I’m trying to add a new or existing version entry to an already existing work package. I get this result:

NoMethodError (undefined method `clear_attribute_changes' for #<WorkPackage:0x007f102dd3b258>):
  lib/plugins/acts_as_customizable/lib/acts_as_customizable.rb:140:in `method_missing'
  app/models/work_package.rb:443:in `update_by!'
  app/services/update_work_package_service.rb:42:in `update'
  app/controllers/work_packages_controller.rb:186:in `update'
  app/middleware/params_parser_with_exclusion.rb:40:in `call'

What is the problem, and how can I get this to work?

Hi Michael,

the issue resulted from a breaking change in a Rails upgrade of one of our plugins during the development of the next stable version (5.0).
It should be fixed when you re-run bundle install on the release/4.2 branch.

There are two relevant work packages that contain more information:
https://community.openproject.org/work_packages/21701
https://community.openproject.org/work_packages/21647

Best,
Oliver Günther
