Hello,

I'm trying to pass a bean as parameter with <a4j:actionparam> in a JSF web app but it doesn't work. I succeed in doing it with a bean attribute, but it's not what I want.

The code of the first bean
FirstBean.java

public class FirstBean
{
 private String name;
 private String id;
 //getters and setters
 ...
}

Code of the second bean
SecondBean.java

public class SecondBean
{
 private FirstBean firstBean

 //getter and setter
 ...
}

In my JSP, there is a data table using a result list which returns a List of FirstBean :

<rich:extendedDataTable value="#{searchBean.resultList}" var="item">
 <rich:column>
 <a4j:commandLink reRender="div_to_render">
 <a4j:actionparam name="item" value="#{item}" assignTo="#{secondBean.firstBean}"/>
 <h:outputText value="#{item.name}"/>
 </a4j:commandLink>
 </rich:column>
</rich:extendedDataTable>

I would retrieve the "item" values in a div like this :

<div id="div_to_render">
 <h:outputText value="#{secondBean.firstBean.name}"/>
</div>

At the beginning, I had the faces-config.xml as follow:

<managed-bean>
 <managed-bean-name>firstBean</managed-bean-name>
 <managed-bean-class>package.FirstBean</managed-bean-class>
 <managed-bean-scope>none</managed-bean-scope>
</managed-bean>

<managed-bean>
 <managed-bean-name>secondBean</managed-bean-name>
 <managed-bean-class>package.SecondBean</managed-bean-class>
 <managed-bean-scope>session</managed-bean-scope>
</managed-bean>

I have no error using this code, but #{secondBean.firstBean.name} is null.

then I add managed-property to make a link with the other bean :
faces-config.xml

<managed-bean>
 <managed-bean-name>firstBean</managed-bean-name>
 <managed-bean-class>package.FirstBean</managed-bean-class>
 <managed-bean-scope>none</managed-bean-scope>
</managed-bean>

<managed-bean>
 <managed-bean-name>secondBean</managed-bean-name>
 <managed-bean-class>package.SecondBean</managed-bean-class>
 <managed-bean-scope>session</managed-bean-scope>
 <managed-property>
 <property-name>firstBean</property-name>
 <property-class>package.FirstBean</property-class>
 <value>#{firstBean}</value>
 </managed-property>
</managed-bean>

No error either in this case, and the bean attributes stay null...

Am I wrong, is it possible to do this ?

Thanks by advance.
