Reacts to actions such as saving and deleting.


Is activated when the page is rendered.

Examples for the use of handlers

Action handlers can be used, for example, to write values from a data record when a new record is saved in a processing context, such as to create a history of a process. An additional example of an application would be to generate IDs, such as NAME_YEAR_CUMULATIVE_NUMBER from various edit fields. If this problem is solved with a handler, neither a specific process nor JavaScript is required. For security reasons, the use of a handler is advantageous as well, since code is run on the server instead of client-side.

Script execution

The scripts are run in the corresponding environment where they are saved – scripts on a page are only run for that page, while scripts in data groups are run on all pages and actions contained in the data group, and scripts in the application node are run application-wide.
