Hi All,
Right now Iam playing with assignment handlers and I have many
confusions.
What will happen when we assign a task to
[1] group
[2] role {member ship name}
what I expected is task should be assigned to all members of group/who
matched role. But here when task is assigned to group, its not getting assigned
to any user and if task is assigned based on role then its getting assigned to
only one user even there exists many users with that role.

|
|
| Please clarify my problems. Is there any link where detailed in-depth
examples are given for assignment handlers.
