ValidateNumber localization i Flow

Question

Am I using this right? For a float value. 12,12 get rejected, 12.12 does not. I want the opposite to be true.

@Flow\Validate(type="Number", options={ "locale"="de_DE" })

Reference here (but no usage example ><)

Actually validation is too late. What you want is map a string 12,12 to a float value 12.12 . This comes before validation. So you need to configure the PropertyMapper. See comments in the \\TYPO3\\Flow\\Property\\TypeConverter\\FloatConverter which are pretty extensive.

Roughly this is what you need:

protected function initializeCreateAction() {
    $this->arguments['newBid']->getPropertyMappingConfiguration()->
        forProperty('yourPropertyThatShouldBeFloat')->
        setTypeConverterOption('TYPO3\Flow\Property\TypeConverter\FloatConverter', 'locale', 'de');
}

For the additional question of accepting both formats 12,12 and 12.12 as float 12.12 you probably need to write your own FloatConverter that checks for the existence of a comma and does either of the two conversions.
