Introduction:

This script has been produced in response to requests from the Enterprise Architect community for a way to display all Connector information for a given diagram. The script displays this information in Enterprise Architect's Search window.

The script iterates over the 'Diagram Link' API collection for a given diagram to retrieve the details of each connector.

Installation Instructions:

1. Open Enterprise Architect's Scripting window.
2. You may create a New Group or place the script within an existing Group.
3. Right click the Group and select the option "New JScript".
4. Label the script "List Connectors".
5. Copy the script below and paste it into the script "List Connectors".
6. Save the script.
7. Select the diagram of interest in the Project Browser. (If it is already open, ensure that changes are saved.)
8. Select the script "List Connectors" and execute it by selecting the "Run script" button.
9. All of the connectors for the selected diagram will appear within Search Window.

Please copy the script below:
