Forcing user registration during the booking process

Is it possible to force the user registration during the booking process.
When the field customer_username marked as required, the system allows you to send the booking form with an empty field customer_username, and thus does not create a new customer. Such designation for an account with a password, a message appears that he must complete this field.

I note that edited the file: components / com_solidres / layouts / asset / guestform.php

You could test it here (2 step booking): htttp: //www.sr.wankom.pl

Sorry for my English but I used the translator.

But the probelm is that I've added this attribute.
And there is not a required field message.

This class is the default field when you click Continue span12 should change the span12 error like all the others, in this case, changes to span12 valid.

I do not know why this happens
If you use firebug will see that this is so.
