Inject with "Spring Security Filter" not working

[mindchild]

I ran a normal Servlet Filter with an injected SessionScope bean without problems.
But within a SpringSecurity-LoginFilter the injected bean has only null value.

Spring Security config goes like this:

web.xml

<filter>
        <filter-name>filterChainProxy</filter-name>
        <filter-class>org.springframework.web.filter.DelegatingFilterProxy</filter-class>
</filter>
<filter-mapping>
        <filter-name>filterChainProxy</filter-name>
        <url-pattern>/*</url-pattern>
</filter-mapping>

security.xml (Spring config)

<bean id="filterChainProxy" class="org.springframework.security.web.FilterChainProxy">
        <sec:filter-chain-map path-type="ant">
                <sec:filter-chain pattern="/*.xhtml" filters="loginFilter" />
        </sec:filter-chain-map>
</bean>
<bean id="loginFilter" class="com.test.filter.LoginFilter" />

LoginFilter.java

@Inject
private ModelBean modelBean;

modelBean is null when Filter is triggered.

Has someone got this working? CDI / Spring Security / DelegatingFilterProxy

Thanks a lot in advance!
