Action
pins and activity parameter nodes have the
following graphical characteristics:
- Pins/parameters
always remain attached to their
action/action block. However, they can be moved around the perimeter
of the action/action block.
- Action pins are
a fixed size. Activity parameters,
however, can be resized.
- Pins/parameters cannot
be copied and pasted.
- All pin/parameter operations
can be undone.
- In the browser, pins/parameters
appear beneath
the action/action block to which they belong.
- When
an action pin / activity parameter is deleted
from a diagram, it is removed from both the view and the model.
