[TYPO3-english] Form Framework in Extension: Custom Finisher in relation to record

[Mikel]

Hi all,

I am implementing the new form framework into an own extension.

My scenario:

- Model „ContactPerson“ has a property „mailAdress“
- Model „ContactPerson“ has a form implemented on it’s showAction
- The form has a „basic setup“ with common fields for all implementations, configured by yaml
- The finisher should be overwritten, when the form is rendered by the showAction of ContactPerson

What is best practise to add a custom finisher in relation to a given model? By „hooking in“ to „initializeFormElement“? Or with a custom finisher? Or with passing a configuration array to form render viewhelper and override the form configuration?

Any hints / discussion / snippets appreciated.
