I made a custom activity with a simple DependencyProperty that I dropped onto my code separation workflow. I then dropped an "IfElseActivity" hoping to use a Declaritive Rule Condition on the DependencyProperty I made in my custom activity. Unfortanately, the Rule Condition Editor does not see my custom activity. If I try this same scenario in a code only workflow, it works without a problem! The Rule Condition Editior sees my custom activity and I am able to use the "Declaritive Rule Condition" without a problem. Has anyone ever run into this? Any solutions?
