[TYPO3-mvc] Verify multiple action arguments at once

[Peter Bücker]

Hi all,

I'm currently looking for ways to verify multiple action arguments at
once. For example, a controller action may have 2 parameters:

/**
 * @param integer $a
 * @param integer $b
 * return string
 */
public function fooAction($a, $b) {
    // ...
}

Is there any way to validate something like $a > $b? If there is no such
thing, has anyone ever written a workaround? I was thinking about adding
a new method annotation like "@dontvalidateAll $a $b
Tx_Ext_Domain_Validation_Validator_FooValidator". As a hotfix, this
could be evaluated in a base controller's initializeAction() method if
I'm not totally wrong.

Thanks for your help!

Regards,
Peter
