I have created a custom workflow activity and successfully deployed it. The issue I am running into is that when I try to select it when creating a workflow using SharePoint designer, nothing happens. It does not get added to the workflow, there are no errors, just nothing. I have been watching the ULS also and nothing is showing up in there either.
Does anyone have any idea why this would happen? Suggestions for where I should start looking?
If there are any parts of the project that will help with this question, let me know and I will post them up.
