When you have multiple brokers in a namespace, clicking on any of them renders *all* the triggers in the namespace, regardless of whether they are assigned to the broker. In the case of removing a broker, the remaining triggers assigned to that broker are still listed in the other brokers content; you can click on them and then click on a link to a non-existent broker (404)

    Always

    1. Create two brokers in the namespace with different names
    2. Create one trigger that is assigned to one broker
    3. Create a second trigger that is assigned to the other broker
    4. Delete one of the brokers
    5. Use the topology to navigate to the broker; click on it, all triggers will be rendered
    6. Click on the trigger that was assigned to the deleted broker
    7. In the trigger content pane click on the name of the deleted broker
    

    Only triggers assigned to the broker should be rendered (and clickable) when the broker content pane is rendered
