Sanitizing Form::DATA_KEYS data type

[maximkou]

Hi! Thanks for good library.

In class Nette\Forms\Form declared 4 data type constants: DATA_TEXT, DATA_LINE, DATA_FILE, DATA_KEYS.

I create custom control and in overrided loaddHttpData method I set data type to DATA_KEYS.

$this->setValue($this->getHttpData(Nutnet_Form::DATA_KEYS));

But Nette\Forms\Helpers::sanitize method throws exception Nette\InvalidArgumentException('Unknown data type'), because for DATA_KEYS not exist sanitizer.

Field named like extraFields[image] and contains array(e.g. extraFields[image][name]). If named array parameter contains array value, library not sanitize this, it's seen in Nette\Forms\Helpers::extractHttpData method.

if (substr($htmlName, -2) === '[]') {
   // if key named, code here not executed
    ...
} else {
    // this is not sanitize DATA_KEYS
    return static::sanitize($itype, $data);
}

This is normally or you forgot add sanitizer and it's bug? (Nette/Forms 2.3)
