"User Task" event in browser based K2 designer for SharePoint workflow does 2 things.
I do't see any similar event from K2 Studio, I tried.
1. Default Client event
2. Form generation client event
3. SharePoint workflow integration client event
None of them gave an option to configure task form in wizard itself like User task.
Is there any equivalent event in K2 Studio for "User Task" in K2 Designer for SharePoint?
The equivalent is the Smartform Client event in K2 Studio. If you don't have that event then it probably means that you need to run the Smartforms setup on your workstation that has K2 Studio to get those Smartform wizards.
