I created a new action by following the basic action example in the SDK 2013. I was able to deploy my solution and activate the features, find the action in the workflow designer and add it to my workflow. What is strange is that the Action button, Labels, Common, and Variables button are disabled in the ribbon. Please see the attached images.
Clicking on Save I get the error message "You must enter an action title" message.
Any ideas what I could be doing wrong?
