beans with bean ref

Hello,
I'm sorry if my question is trivial but i can not find solution.
I have a beans:
<bean id="prodMan" class="bus.ProductManager">
        <property name="products">
            <list>
                <ref bean="product1"/>
                <ref bean="product2"/>
                <ref bean="product3"/>
            </list>
        </property>
        <dwr:remote javascript="prodMan"></dwr:remote>
    </bean>

    <bean id="product1" class="bus.Product">
        <property name="description"><value>Lamp</value></property>
        <property name="price"><value>5.75</value></property>
        <dwr:remote javascript="product1"></dwr:remote>
    </bean>
And if i access them with DWR, i can get the values of product1 but dwr shows 
me empty list for bean prodMan. 
Can somebody give me a hint?
regards,
keneida
