Reacts to actions such as saving and deleting.
Renderinghandler

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 in which 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.
Add handler definition
Opens a dialog where a new handler definition can be created.
