Using p:resetInput along with Spring bean in PrimeFaces 3.5


Tag : spring , By : 66.
Date : March 29 2020, 07:55 AM
I think the issue was by ths following , I'm trying to use as it stands for. This works fine until I annotate a JSF bean with @org.springframework.stereotype.Controller. , This worked, when I changed the managed bean like so,
@Controller
@Scope("view")
public final class testManagedBean extends LazyDataModel<Bean> implements Serializable
{
    private String txtName; //Getter and setter.
}
<p:commandButton id="btnSubmit" update="panel" actionListener="#{testManagedBean.submit}" icon="ui-icon-check" type="submit" ajax="true" value="Save"/>

<p:commandButton value="Reset" update="panel" process="@this">
    <p:resetInput target="panel" />
</p:commandButton>

wish of those help To Enable @Autowired annotation, you have to add in Spring config file (Users bean xml file). You have to add context namespace as well
xmlns:context="http://www.springframework.org/schema/context"
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns:context="http://www.springframework.org/schema/context"
    xsi:schemaLocation="http://www.springframework.org/schema/beans 
    http://www.springframework.org/schema/beans/spring-beans-2.5.xsd">

    <context:annotation-config />

    <bean id="loginAction" class="com.riteshsangwan.ossoc.actions.LoginAction">
        <property name="ubo" ref="usersBo" />   
    </bean>

    <bean id="usersBo" class="com.riteshsangwan.ossoc.business.UsersBoImpl" >
        <property name="udao" ref="usersDAOImpl" />
    </bean>

    <bean id="usersDAOImpl" class="com.riteshsangwan.ossoc.business.UsersDAOImpl" >
        <property name="sessionFactory" ref="sessionFactory" />
    </bean>

</beans>

NullPointerException from Remember-me on a Spring Bean

I hope this helps you . I found the solution. I changed the "customjdbcUserService" with the "userDetailsService" in the jsfspring-sec-bean-config.xml and jsfspring-sec-security-config.xml and now the userDetailsService gets the correct values from the database, so it is not null anymore.
