[FLOW3-general] Own TypeConverter

[Manfred Rutschmann - VOLUMEN Werbe-/Internetagentur]

Hi list,

one question about type converter:

In my model i have a field named estimatedtime, stored with seconds in the database. In the frontend the user can make this input:

1h 30min

I have written a own simple typeconverter like this:

I used this converter in my initializeUpdateAction:

    /**
     * initializeCreateAction
     * @return void
     */
    public function initializeUpdateAction() {
        $this->arguments["aufgabe"]
            ->getPropertyMappingConfiguration()
            ->forProperty('faellig')
            ->setTypeConverterOption('TYPO3\FLOW3\Property\TypeConverter\DateTimeConverter', \TYPO3\FLOW3\Property\TypeConverter\DateTimeConverter::CONFIGURATION_DATE_FORMAT, 'd.m.Y H:i');

        $this->arguments["aufgabe"]
            ->getPropertyMappingConfiguration()
            ->forProperty('estimatedtime')
            ->setTypeConverterOption('Kunden\Property\TypeConverter\HourMinuteToSecondsConverter', 'integer', NULL);
        
        $this->arguments['aufgabe']->getPropertyMappingConfiguration()->allowProperties('company');
        $this->arguments['aufgabe']->getPropertyMappingConfiguration()->allowProperties('projekt');
    }

I have set the converter here only for the property estimatedtime, but flow applies this Converter to ALL defined integers in my model. 
Because of this i get by every property on the form that is defined as integer a error like "No hour or Minute give"

Why? I have no idea...

Thanks & regards Manfred
