Problem with dropdownDescriptorSelector

[Dimitri CHARLES]

What I am trying to do is to save the properties of the Scala class and the 
Jahia class. For that I defined a Profil class which is abstract and those 
class extend Profil. 
 
I have a config.jelly where I use the taglib f:drowDownDescriptorSelector  :

<f:dropdownDescriptorSelector title="Profils" field="profil" 
descriptors="${it.profilDescriptors}" />

and the associated class : 

private final Profil                        profil;

 @DataBoundConstructor
    public RemoteDeploymentBuilder(Profil profil, String environment, 
String component, String version)
    {
        this.environment = environment;
        this.profil = profil;
        this.component = component;
        this.version = version;
    }

My problem is that the properties of each class (Jahia and Scala)  are 
properly saved but they do not display properly, the textboxes where I 
defined them are empty. How can I solve that? 
Here is the profil class and his subclass : 

public static abstract class Profil implements Describable < Profil >
    {

        protected String name;

        private Profil(String name)
        {
            this.name
 
 = name;
        }        

        public String getName() {
return name;
}

public Descriptor < Profil > getDescriptor()
        {
            return Jenkins.getInstance().getDescriptor(getClass());
        }
    }

    public static class ProfilDescriptor extends Descriptor < Profil >
    {

        public ProfilDescriptor(Class < ? extends Profil > clazz)
        {
            super(clazz);
        }

        @Override
        public String getDisplayName()
        {
            return clazz.getSimpleName();
        }
    }

    public static class Jahia extends Profil
    {
        private String tomcatService, jahiaWebApp;

        @DataBoundConstructor
        public Jahia(String tomcatService, String jahiapublic static 
abstract class Profil implements Describable < Profil >
    {

        protected String name;

        private Profil(String name)
        {
            this.name  = name;
        }        

        public String getName() {
return name;
}

public Descriptor < Profil > getDescriptor()
        {
            return Jenkins.getInstance().getDescriptor(getClass());
        }
    }

    public static class ProfilDescriptor extends Descriptor < Profil >
    {

        public ProfilDescriptor(Class < ? extends Profil > clazz)
        {
            super(clazz);
        }

        @Override
        public String getDisplayName()
        {
            return clazz.getSimpleName();
        }
    }

    public static class Jahia extends Profil
    {
        private String tomcatService, jahiaWebApp;

        @DataBoundConstructor
        public Jahia(String tomcatService, String jahiaWebApp)
        {
            super("deploy-jahia-module");
            this.tomcatService = tomcatService;
            this.jahiaWebApp = jahiaWebApp;
        }

        public String getTomcatService()
        {
            return tomcatService;
        }

        public String getJahiaWebApp()
        {
            return jahiaWebApp;
        }

        @Extension
        public static final ProfilDescriptor descriptor = new 
ProfilDescriptor(Jahia.class);

    }

    public static class Scala extends Profil
    {
        private String scalaRootDir;

        @DataBoundConstructor
        public Scala(String scalaRootDir)
        {
            super("deploy-play-module");
            this.scalaRootDir = scalaRootDir;
        }

        public String getScalaRootDir()
        {
            return scalaRootDir;
        }

        @Extension
        public static final ProfilDescriptor descriptor = new 
ProfilDescriptor(Scala.class);
    }WebApp)
        {
            super("deploy-jahia-module");
            this.tomcatService = tomcatService;
            this.jahiaWebApp = jahiaWebApp;
        }

        public String getTomcatService()
        {
            return tomcatService;
        }

        public String getJahiaWebApp()
        {
            return jahiaWebApp;
        }

        @Extension
        public static final ProfilDescriptor descriptor = new 
ProfilDescriptor(Jahia.class);

    }

    public static class Scala extends Profil
    {
        private String scalaRootDir;

        @DataBoundConstructor
        public Scala(String scalaRootDir)
        {
            super("deploy-play-module");
            this.scalaRootDir = scalaRootDir;
        }

        public String getScalaRootDir()
        {
            return scalaRootDir;
        }

        @Extension
        public static final ProfilDescriptor descriptor = new 
ProfilDescriptor(Scala.class);
    }

How can I solve this problem?
