Hi,
I am using the jPDL for defining the work flow and also validate the fields in the form using the ajax rerender feature. If I enter invalid data to the field (e.g. leave the form empty for required fiedl) and leave the input, the validation work fine, the message is displayed that I left the field empty (what indicates that the validation is set-up properly).
But when I send the data to the server by the nodes defined in jPDL, the data are sent allthrough some required fields are emtpy (or e.g. wrong number format is provided).
I dont want to validate explicitly by using expression in the jPDL, if there is powerful validation framework built in Seam...

Does anyone know where the problem is? Maybe I missed something really important on inserting the data by using jPDL.

Here is the code:

Starting the pageflow:

<s:button action="#{companyHome.start}" value="#{messages.label_edit}" id="editCompany">
 <f:param name="companyId" value="#{companyHome.instance.id}" />
</s:button>

pageflow edit company:

<?xml version="1.0"?>

               <action expression="#{companyHome.update}" />
          </transition>
          <transition name="false" to="complete">
               <action expression="#{companyHome.persist}" />
          </transition>

     <page name="completeDelete" view-id="/portfolio/portfolio.xhtml"
          no-conversation-view-id="/portfolio/portfolio.xhtml">

CompanyHome (Seam framework)

@Name("companyHome")
@Restrict("#{identity.loggedIn}")
@Scope(ScopeType.CONVERSATION)
public class CompanyHome extends EntityHome<Company>
{

    private static final long serialVersionUID = 9057915693870914547L;

    @RequestParameter
    Integer companyId;

    @RequestParameter
    String action;

    @In(value = "currentUser")
    User currentUser;

    @In(create = true)
    ProductHome productHome;

    @Begin(join = true, pageflow = "editCompany")
    public String start()
    {
        setCompanyId(companyId);

        if (action == null || "".equals(action))
        {
            return CCConstants.OUTCOME_EDIT;
        }
        return action;
    }

    public void setCompanyId(Integer companyId)
    {
        if (companyId != null)
        {
            setId(companyId);
        }
    }

    public Integer getCompanyId()
    {
        return (Integer) getId();
    }

    @Override
    protected Company createInstance()
    {
        Company company = new Company();
        company.setUser(currentUser);
        return company;
    }


}

The edit company xhtml:

     <ui:define name="body">

          <h:form id="companyEditForm">

               <s:decorate template="../layout/editBox.xhtml" id="editBox">

                    <ui:define name="header">
                         <h:outputText value="#{companyHome.managed ? 'messages.label_company_edit': 'messages.label_company_create'}" />
                    </ui:define>

                    <ui:define name="buttons">
                         <s:button id="saveCompany" value="#{companyHome.managed ? messages.label_edit : messages.label_create}" action="save" disabled="#{companyBean.validationFailed}" />
                         <s:button id="cancelCompany" value="#{messages.label_cancel}"
                              action="cancel" />
                    </ui:define>

                    <s:decorate id="nameDecoration"
                         template="../layout/edit.xhtml">
                         <ui:define name="label">#{messages.label_name}</ui:define>
                         <h:inputText required="true"
                              value="#{companyHome.instance.name}">
                              <a:support event="onblur" reRender="nameDecoration" />
                         </h:inputText>
                    </s:decorate>
                    
               </s:decorate>

          </h:form>

     </ui:define>

and the Entity bean Company:

@Entity
@Table(name = "company")
public class Company implements Serializable, Idable<Integer>
{

    private static final long serialVersionUID = 8106268264760054294L;

    @Id
    @GeneratedValue
    @Column(name = "id", unique = true, nullable = false)
    private Integer id;

    @NotNull
    @Required
    @Capitalized
    private String name;

    @OneToMany(mappedBy = "company", fetch = FetchType.LAZY, cascade = CascadeType.ALL)
    private Collection<Product> products = new ArrayList<Product>(0);

    @ManyToOne
    @NotNull
    private User user;

    //getters and setters...
