Answer 1

Looks like there're no participants assigned to a role under which the task is executed. In your JDeveloper open "Organization" section and check the members for that role.
You can also check the task definition in the Assignment part what is the Participant List (by default the list should be created using Lane Participants / Current Lane Participants).
