Create Custom Events | Publish Custom Events | Subscribe to Custom Events
Each workflow in the Process Designer starts with an Event.
| Click on the Event element under Activities on the left side and drag & drop it into the drawing area in the center. |
 |
| By double-clicking on the shape, the event selection assistant opens. You can also open it by clicking on the right side underneath Subscribe event / Publish event. |
 |
It guides you to your required event. When subscribing to an event, you can select events from these categories: Widget Events, Screen Events, Custom Events and System Events.
Each category is sorted and searchable.
If you want to use the Event in the current user story, select one of the Events under the tab Subscribe Event.

| Screen Events | Events related to screens, e.g. onInit and onAfterShow. |

Subscribe to Custom Events
Subscribe to a custom event in another user story to connect the logic between different user stories.
Example:
You have a process in User Story 1 that contains a condition to check if an input field is filled out after clicking on a “Login” button. Afterwards, the user should be navigated forward to the next screen.
Imagine you have the other user story exclusively for the whole navigation of your application. So you want the end of the event from User Story 1 (the navigation) subscribed to User Story 2.
Therefore we published the new Custom Event “LoginButton” in User Story 1 and subscribed to it in User Story 2.
