inside jsf-spring-aspects.jar there is a AJ File.

Is this correct, is there some further config I am missing?

JSF/SWF/JBoss

Hello James,

if you want to use the jsf-spring-aspects.jar you have to compile/recompile your sources (and your JSF implementation btw) with AspectJ. It's a moot point whether you need to deploy the jsf-spring-aspects.jar. If you want to inject dependencies on UIComponents, Validators or Converters you have to. For further information please have a look at http://jsf-spring.sourceforge.net/schema/jsf/jsf-spring.xsd and http://jsf-spring.sourceforge.net/4.0RC1/de/mindmatters/faces/spring/factory/aspectj/package-summary.html.

I'm new to this so I'm not exactly sure what I need right now.

What I am trying to achieve is quite simple, but made a little more complex because I'm using Spring Web Flow.

Bascially in my facelet I have an expression which is trying to bind a nested property but isnt working.

#{parent.value1} <- OK
#{parent.child.value2} <- FAILS

I was hoping that jsf-spring would solve my problem...and I correct?.

[Andreas Kuhrwahl]

Hi James,

i need to know the type of 'parent'! If it's of type UIComponent it won't work (neither with jsf-spring).

[James Clinton]

parent is a bean.  Here's a clear example which should help.

public class UserAddCommand .. {
  private User user;
  private String text;
  //get/sets
}

public class User .. {
  private String text;
  //get/sets
}

--Configure spring beans in appCtx
<bean name="userAddCommand" class="abc.UserAddCommand" scope="prototype" />
<bean name="test" class="abc.Test" scope="prototype" />

I've tried adding the User into faces-config.xml but without success.

#{userAddCommand.text} works.
#{userAddCommand.user.text} fails.

THANKS.

[Andreas Kuhrwahl]

Hi James,

the User of the UserAddCommand is null. You have to set a User programmatically or via DI in the config file.

[James Clinton]

The UserAddCommand is declared in spring.

Using JSF-EL to extract a string also works, problems arise when getting nested elements:

--user add command obj.

<bean
id="userAddFormAction"
class="org.springframework.webflow.action.FormAction">
<property name="formObjectName" value="userAddCommand" />
<property name="formObjectClass" value="abc.UserAddCommand" />
<property name="formObjectScope" value="FLOW" />
</bean>

Getting to the Test object in UserAddCommand is where I am struggling.  I have tried to declare the bean in spring appCtx and faces-config but without luck.

I have also tried adding it into 'faces-spring-context'...still no joy.

Any thoughts?

kind regards.

[Andreas Kuhrwahl]

Hi James,

don't get me wrong but i do not see any piece of code where a user ist created (neither a 'new User()' nor a <bean id="myUser" class="abc.User"...> or something similar).

Kindly regards

Andy

Add this kind of config in the faces-config.xml.

<managed-bean>
        <managed-bean-name>userAddCommand</managed-bean-name>
        <managed-bean-class>UserAddCommand</managed-bean-class>
        <managed-property>
            <property-name>user</property-name>
            <value>#{user}</value>
        </managed-property>
    </managed-bean>
<managed-bean>
        <managed-bean-name>user</managed-bean-name>
        <managed-bean-class>User</managed-bean-class>
    </managed-bean>

[James Clinton]

No worries ;)

My mistake inthe previous post, test should of been user..

-----------------------------------------------------------------------------------------
public class UserAddCommand .. {
private User user;
private String text;
//get/sets
}

public class User .. {
private String text;
//get/sets
}

--Configure spring beans in appCtx
<bean name="userAddCommand" class="abc.UserAddCommand" scope="prototype" />
<bean name="user" class="abc.User" scope="prototype" />              <---------- ### CORRECTION ####

<bean 
id="userAddFormAction" 
class="org.springframework.webflow.action.FormAction">
<property name="formObjectName" value="userAddCommand" />
<property name="formObjectClass" value="abc.UserAddCommand" />
<property name="formObjectScope" value="FLOW" />
</bean>

I've tried adding the User into faces-config.xml but without success.

#{userAddCommand.text} works.
#{userAddCommand.user.text} fails.
-----------------------------------------------------------------------------------------

This is all spring config. I have tried declaing user in faces-config, but without success.

Thanks again, really need to solve this one quickly.

[Andreas Kuhrwahl]

try this:

<bean name="userAddCommand" class="abc.UserAddCommand" scope="prototype">
    <property name="user" ref="user"/>
</bean> 
<bean name="user" class="abc.User" scope="prototype" />

[James Clinton]

Yes that has resolved it. Cant believe i missed that.

Thanks so much.
