[Security 3.1.2] After logout, first attempt login forward to login page

Hi everybody,
i start to use Spring security recently.
All works fine except one thing. Login after a logout.
If i try to login after a logout, i'm directly forward to the login page, instead of my home page.
At the second attempt it work like attended.
I check in debug mode if something go wrong, but as far i can see, all work perfectly. My UserDetailsService get the right user and GrantedAuthority.
So the issue seems to come from the forwarding.
I suspect it come from the DelegationActionProxy for struts, the login success forward to a Struts Action.
I will check this way but in the same time i'll be gratefull if someone can check my spring security context file to let me know if something is wrong.

Code:

<http use-expressions="true" auto-config="true">
                <form-login login-page='/login.jsp'
                                        login-processing-url='/j_spring_security_check'
                                      authentication-failure-url="/login_error.jsp"
                                        default-target-url='/home.do'/>

                                logout-url="/logout"/>
        </http>

        <authentication-manager>
                <authentication-provider user-service-ref="myUserDetailsService"/>
        </authentication-manager>
       
        <beans:bean id ="myUserDetailsService" class="com.coff.front.mod.safec2c.security.UserDetailsServiceImpl">
                <beans:property name="h2Dao" ref="H2DaoBean"/>
        </beans:bean>
