Parameters synchronization keeps your model valid and synchronized after making changes. How does the synchronization work? After you have created a new element or edited a property the associated elements and properties are updated according to your changes.
The following table lists the pairs of elements that are synchronized.
| Synchronized Elements | The backward | |
|---|---|---|
Behavior (Parameter) | Operation (Parameter) | Yes |
| Operation (Parameter) | Call Operation Action (Pin) | Yes |
| Behavior (Parameter) | Call Behavior Action (Pin) | Yes |
| Signal (Attribute) | Send Signal Action (Pin) | Yes |
| Signal (Attribute) | Accept Event Action (Pin) | Yes |
| Activity (Parameter) | Activity (Activity Parameter Node) | Yes |
| Behavior (Parameter) | Signal Reception (Parameter) | Yes |
| Operation (Parameter) | Message (Argument) | No |
| Interaction (Parameter) | Interaction Use (Argument) | No |
| Signal (Attribute) | Message (Argument) | No |
The following table lists the synchronized element properties and conditions on which these properties are synchronized.

| Behavior (Parameter) | Operation (Parameter) | always | always | always | always |
