In sequence diagrams, partitions in activity diagrams,
and regions in state machine diagrams, by default, any changes that
you make to the model are reflected in the diagrams that represent
the model. Conversely, any changes that you make to the diagram
are reflected in the model. You can set the canonical property to
false so that changes in the model are not synchronized with the
diagram.
You must have an activity diagram, a sequence
diagram, or a state machine diagram open in the Modeling perspective.
To remove synchronization between the model and its diagrams:
- Complete one of the following steps:
- In an activity diagram, click in a partition.
- In a sequence diagram click in the contents area, below
the header.
- In a state machine diagram, click a region.
- In the Properties view, click the Advanced tab.
- On the Advanced page, expand the View heading.
- Under Styles, for the Canonical property,
in the Value box, select false.
