Subject: NEW ISSUE: Comment propagation
TARGET: BPEL4People DESCRIPTION: Sometimes the comments that are collected during the execution of one
people activity need to be visible to people working on later people
activities. This is not currently possible. It also should be possible to access the comments of a task from XPath
expressions in the B4P process. This would make it possible to record the
comments in some other document. PROPOSED RESOLUTION: Introduce a new child element of a people activity: <b4p:propagateCommentsFrom> <b4p:activityRef>peopleActivityName</b4p:activityRef>* </b4p:propagateCommentsFrom> This causes any comments that are present on the named people
activities to be copied into the context of the target activity at the time
that the target activity becomes ready to execute. If more than one activity
in the process has a name referenced from a <b4p:activityRef> element,
then all matching activities have their comments propagated. Since comment IDs
are unique only within a single task, when comments are propagated they may get
new IDs. We should also add a new XPath function
“b4p:getComments(activityName)”, which returns the comments for a
task using WS-HT’s existing tComment type. To support these changes, the tHumantTaskContext type needs to change
to include a <comments> child element, analogous to the
<attachments> element. |
