The documentation says (see ):
An example of a custom incident handler could be a handler which, in addition to the default behavior, also sends an email to an administrator.
This could be a misleading, so that someone thinks that he just have to add a custom incident handler to do something in addition to the default behavior. But adding a custom incident handler for example for the incident type failedJob overwrites the default behavior with the custom incident handler. As a consequence, the default incident handler is not executed anymore. If the default behavior should be executed, then the custom incident handler must also invoke the default incident handler.
- improve the documentation so that it is clear what to do if something should happen in addition to the default behavior
