When creating a workflow with a task (Request Approval, Flexi Task and Request Data) action and attempting to click on "Edit with Nintex Forms", it attempts to load and then does nothing.
This behavior also occurs when importing a workflow from an older version of Nintex Workflow into a newer version of Nintex Workflow. Typically imported into a Dev environment from Production for testing before upgrading to the latest version.
1. Verify the Workflow has been published in the upgraded environment. 2. Deactivate and reactivate the "Nintex Forms for Nintex Workflow" feature at the Site Collection level:
A. Go to Site Settings > Site Collection Administration > Site Collection Features. B. Deactivate the "Nintex Forms for Nintex Workflow" feautre C. Activate the "Nintex Forms for Nintex Workflow" feature
3. Any new workflow being imported into the upgraded environment will need to be published and the Workflow Designer will need to be closed and reopened.
