[TYPO3-dev] Extbase: Setting relational field to empty using frontend´

[Henjo Hoeksma | Stylence]

Like I said in my response to Stefano, it would be better to check in your
setter method of your model to check wether something is NULL or not.
If it is some fancy checking you need to do, you could write a Domain
Utility of Custom Domain Object Validator to do so.

Take a look at the validator classes to see what it possible there.

When putting this stuff in your controller you are placing domain logic in
your application, instead of keeping it in the domain.
Doing this you will find yourself repeating code to achieve the same things
over and over and you are on a fast track of getting into trouble ;-)

Kind regards,

Henjo

Problems are small because we learned how to deal with them.
