[Flow] Creating Account and own object at once

[Daniel Völkel]

Ok, now I have my DTO and my controller. There is just one thing I'm confused about: where do I create my account with
$account = $this->accountFactory->createAccountWithPassword($username, $password, array($role));

Will this part remain in my controller or will it be in my DTO? And how do I access username and password from my form:

<f:form.textfield name="account.username" id="username"  />
<f:form.password name="account.pass" id="pass" />

Best regards,
Daniel
