How are group objects handled?

Elements are assigned to a process via a connection of the belongs to type. A process is represented by an object of the Pool or Lane type.

The figure shows a group object.

Group in BPMN

If the group is arranged in an object of the Pool or Lane type, an element that belongs to this group has at least two connections of the belongs to type. An element has connections of the belongs to type to each group to which it belongs and also a connection of the belongs to type to the object of the Pool, Lane, or Subprocess type to which it belongs.

Delete

If a group is deleted, the elements remain. However, if a pool is deleted, all of the elements in the pool are also deleted.

Copy or cut

When you copy or cut the group, its elements are not copied or cut.
