[bpel4people] NEW ISSUE: Title: Outcome field is missing from task view

["Mark Ford" <mark.ford@activevos.com>]

TARGET: HT, Section 6.1

DESCRIPTION: The outcome field for a task is defined in Section 4.2 as a
query that is run against the output message in order to produce an
xs:string that represents the business result of the task. This field
doesn't appear in the task view described in Section 6.1 where an
application can get a list of tasks. It seems like a simple omission from
the list of fields that come back when requesting a listing of tasks.

I also think it's worth considering adding a custom function to b4p to get
the outcome from a people activity but this will be opened as a separate
issue pending the outcome of this issue (no pun intended).

PROPOSAL:
