获取从DataTable中选择的行元素，然后传递给另一个JavaBean

Question

我在以下项目中遇到了一些问题。目标是当用户选择编辑列命令按钮时，将调用另一个JavaBean。

这是我的clients.xhtml文件：

    <ui:define name="title">Companies</ui:define>

    <ui:define name="content">
        <h:form id="form">
            <div class="ui-g">
                <div class="ui-g-12">
                    <div class="card card-w-title">
                        <p:toolbar>
                            <f:facet name="left">
                                <p:button value="New company" icon="ui-icon-plus"
                                    outcome="createClients.xhtml" />
                            </f:facet>

                            <f:facet name="right">
                                <p:commandButton type="button" title="Delete"
                                    icon="ui-icon-delete"
                                    actionListener="#{clientsSelectionView.onRemove()}" />
                            </f:facet>
                        </p:toolbar>
                        <p:dataTable var="company"
                            value="#{clientsSelectionView.companies}" selectionMode="single"
                            reflow="true" selection="#{clientsSelectionView.selected}"
                            rowKey="#{company.pk}" paginator="true" rows="10">
                            <f:facet name="header">
                                Company
                            </f:facet>
                            <p:column headerText="Nome" sortBy="#{company.name}">
                                <h:outputText value="#{company.name}" />
                            </p:column>
<p:column style="width:32px;text-align: center">
                                <p:commandButton
                                    icon="ui-icon-edit"
                                    title="View" action="#{clientsSelectionView.onEditCompany(company)}">

                                </p:commandButton>
                            </p:column>
                        </p:dataTable>
                    </div>
                </div>
            </div>
        </h:form>
    </ui:define>

这是xhtml文件的JavaBean：

    @Named(value = "clientsSelectionView")
@SessionScoped
public class ClientsSelectionView implements Serializable {

    @Inject
    CompanyController clientController;
    private List<Company> companies;
    private Company selected;

    @PostConstruct
    public void init() {
        this.companies = clientController.getAllClients();
    }

    public List<Company> getCompanies() {
        return companies;
    }

    public void setCompanies(List<Company> companies) {
        this.companies = companies;
    }

    public Company getSelected() {
        return selected;
    }

    public void setSelected(Company selected) {
        this.selected = selected;
    }

    public void onRowSelect(SelectEvent event) {

        FacesMessage msg = new FacesMessage("Car Selected", ((Company) event.getObject()).getName());
        FacesContext.getCurrentInstance().addMessage(null, msg);
        System.out.println("Sno qui");

    }

    public void onRowUnselect(UnselectEvent event) {
        FacesMessage msg = new FacesMessage("Car UnSelected", ((Company) event.getObject()).getName());
        FacesContext.getCurrentInstance().addMessage(null, msg);
    }

    public void onRemove() {
        System.out.println("Ciao " + selected);
    }

    public void onEditCompany(Company company) {

        System.out.println(company.getName());
        FacesContext.getCurrentInstance().getExternalContext().getFlash().put("company", selected);
        try {
            FacesContext.getCurrentInstance().getExternalContext().redirect("./clients.xhtml");
        } catch (IOException e) {
            e.printStackTrace();
        }
    }

}

这是目标JavaBean：

@Named
@RequestScoped
public class CreateCompanyView implements Serializable {

    @Inject
    CompanyController companyController;
    private Company company;

    @PostConstruct
    public void init() {
        this.company = new Company();
    }

    public boolean canDelete() {
        return true;
    }

    public void save() {
        System.out.println(company.getName());
        companyController.store(company);
        info();

        try {
            FacesContext.getCurrentInstance().getExternalContext().redirect("./clients.xhtml");
        } catch (IOException e) {
            e.printStackTrace();
        }
    }

    public void delete() {
        companyController.remove(company);
    }

    public Company getCompany() {
        return company;
    }

    public void setCompany(Company company) {
        this.company = company;
    }

    public void info() {
        FacesContext.getCurrentInstance().addMessage(null,
                new FacesMessage(FacesMessage.SEVERITY_INFO, "Ok", "L'ordine è stato salvato correttamente!"));
    }
}

该模式在哪里出错？如何在与JavaBean链接的xhtml和JSF中的另一个JavaBean的另一个xhtml之间传递数据？是否有任何简单的解决方案来执行这种操作而又没有太多麻烦？
