The ASDK 2.0 that workflow uses turns out to be picky with the type of task you create on the Notification Server. I was creating a "Update Client Configuration" Task and it wasn't picking it up when I pulled the tasks from Workflow. The solution was to select
Client Task when creating the task on Notification server then Workflow can see it.
In case someone didn't know how to retrieve the tasks from Workflow:
In Designer:
Create Integration Library
Give it a random name (It doesn't retain the name)
Scroll down to the Symantec Workflow for NS 7.0 section
Select ASDK Tasks Component Generator for NS 7.0
Say Yes to the Singleton Generator question
Select NS Creds -> Continue
Takes a min to retrieve the tasks from the NS
Select all or just the task you created
Recompile and close
Hope this helps someone.
