Shield views with modals

Hello Community.

I am using shield and I have a little problem. I use modals for registration, login and magic-login. If the credentials
are okay (all forms passes validation without errors), there are no problems.
But if wrong credentials or invalid data submitted shield redirect to the default views and show errors there.
My question: how to modify sourcecode that the errors are shown in my modals.

Best regards,

Kighlander...
