Feature request login

I don´t know if this is really a feature request or if I can achieve this by other means.
When using the CB login on a module position and a user makes a mistake, for example he does submit the module with empty fields, there is a redirect, loading the module again but this time in main component area.
This looks weird when the CB login module is showing at the same time.

Wouldn´t it be much nicer if there was an error message within the module without changing the main area?

Joomla behaves exactly the same. The reason for this is the module is just posting to the internal user login page. When there is an error it just errors at the login page. This will not be changed, sorry. You can redirect away using CB Auto Actions though on the onBeforeLoginFormDisplay trigger and check that [var2] is not empty (if it's not empty then an error occurred).
