$builder->testPhrase always returns false about captcha

@arif may i know wht happened.
first you generate the verif image,but the verify content($phrase) conntent not be saved.it's the fitst lifecycle,
and the you use form to validate,it's wrong,to see this part of code in class CaptchaBuilder

 public function __construct($phrase = null, PhraseBuilderInterface $builder = null)
    {
        if ($builder === null) {
            $this->builder = new PhraseBuilder;
        } else {
            $this->builder = $builder;
        }

        if ($phrase === null) {
            $phrase = $this->builder->build();
        }

        $this->phrase = $phrase;
    }

from post is another lifecycle,this time you call new CaptchaBuilder again, so the $phaser is null and will be regenerate,do you anderstand what i said?

so my solution is just $buildre->getPhaser() and save to session used to validate
