We currently handle failed WorkflowController#create actions by collecting the errors in the object and redirecting to the original new form. However as soon as we click save and call the create action, the page redirects from ...workflows/new to .../workflows, and this persists even if the create action is unsuccessful. While this usually isn't an issue, since this would take you to the index, there is no index action defined on workflows and this leads to an error. We should either keep the url the same through validation and correction (on the new path) or make .../workflows an alias for ProjectsController#show, which fills the workflow index function.
