    Error "Something Went Wrong" When Configuring Task Actions

    Summary
    When configuring an Assign Task, Assign Flexi-Task, or Request For Approval action, after installation or after upgrading Nintex, the action configuration window might display the following error: Something went wrong. And in the ULS logs you see: Application error when access /_layouts/15/NintexWorkflow/MultiOutcomeDialog.aspx, Error=Object reference not set to an instance of an object.

    Solution
    Retract and remove all of the Nintex Workflow solutions, and re-run the workflow installer. This will push new solutions to the farm, and verify that all .aspx files have been properly pushed to the SharePoint Hive.
