Question

我正在使用primeFaces 3.4.2并实现了带有排序，过滤的延迟加载数据表。我试图在上面提到的数据表中嵌入另一个数据表。

出于上述目的，我使用了行扩展和行切换。

我的场景是这样的

public class Customer {
    @Id
    private Long id;
    private String name;
    private String email;

    @JoinColumn(unique = true, name = "Cust_Details_Id" )
    @OneToOne(cascade = CascadeType.ALL)
    private CustomerDetails customerDetails;
}

public class CustomerDetails {
    @Id
    private Long cdId;

    @OneToOne(mappedBy = "customerDetails", cascade = CascadeType.ALL)
    private Customer customer;

    @OneToMany(mappedBy = "customerDetails", cascade = CascadeType.ALL)
    private List<TypeA> listOfTypeA = new ArrayList<TypeA>(); 

    @OneToMany(mappedBy = "customerDetails", cascade = CascadeType.ALL)
    private List<TypeB> listOfTypeB = new ArrayList<TypeB>();;
}

public classTypeA {
    @Id
    private Long typeAId;

    @ManyToOne(cascade = CascadeType.ALL)
    private MeasurementDetails measurementDetails;    

    // Around 10-12 fields to store its details
}

public classTypeB {
    @Id
    private Long typeBId;

    @ManyToOne(cascade = CascadeType.ALL)
    private MeasurementDetails measurementDetails;    

    // Around 12-15 fields to store its details
}

//我正在使用LazyLoading，如下面的代码

<p:dataTable id="dataTable" 
var="customer" 
value="#{customerController.lazyModel}" 
styleClass="userDataTableStyle"
paginator="true" 
rows="10" 
selection="#{customerController.selctedCustomers}"
paginatorTemplate="{CurrentPageReport}  {FirstPageLink} {PreviousPageLink} {PageLinks} {NextPageLink} {LastPageLink} {RowsPerPageDropdown}"
lazy="true" 
rowsPerPageTemplate="10,15,50" >

<f:facet name="header">Customer List</f:facet>  

<p:column> <p:rowToggler id="rowToggler" /> </p:column>            
<p:column selectionMode="multiple" style="width:18px" />  

<p:column headerText="First Name" sortBy="#{customer.firstName}" filterBy="#{customer.firstName}">
    <f:facet name="header"> <p:outputLabel  value="First Name" /> </f:facet>

    <p:commandLink value="#{customer.firstName}" update=":customerDetailForm:display" oncomplete="custDialog.show()"  title="View">
        <f:setPropertyActionListener value="#{customer}" target="#{customerController.selectedCustomer}" />    
    </p:commandLink>
</p:column>

<!-- Other Columns -->
<!-- I want to embed another data here but based on the previous selected customers row Toggle -->

<p:rowExpansion  id="expand" rendered="true"  >  

    <p:dataTable id="dataTableInner" 
        var="cust" 
        value="#{customerController.selctedCustomers}" 
        styleClass="userDataTableStyle"
        lazy="true" rowsPerPageTemplate="10,15,50">

    <f:facet name="header"> Customer Details </f:facet>

    <p:column headerText="Customer Details " sortBy="#{customer.customerDetails}" >
        <f:facet name="header">
            <p:outputLabel  value="Customer Details" />
        </f:facet>
        <p:outputLabel  value="#{customer.customerDetails.customerId}" />
    </p:column>

    <p:column headerText="Mas ccc" >
        <f:facet name="header">
            <p:outputLabel  value="Date" />
        </f:facet>
        <p:outputLabel  value="#{customer.customerDetails.TypeA[0]}" /> <!-- Example -->
    </p:column>

    </p:dataTable> <!-- Inner datatable -->
</p:rowExpansion> 
</p:dataTable> <!-- Outer datatable -->

问题
1.我如何知道哪个客户是“Row Toggeled”而不是通过我用于删除的Checkbox 2.我想显示TypeA和TypeB的dataTable（如果数据存在于列表中），它会在行转换器上被触发。 3.我正在维护customerDetails类以跟踪TypeA和TypeB的列表，我可以删除这个类，只需将列表粘贴到客户类中吗？

//在客户明细类中，它可以有零或一个TypeA列表，类似于TypeB 如果我的设计不正确，请帮助我，并提供一些指示，以便我可以使其工作

primeFaces LazyLoading数据表在另一个dataTable和rowExpansion中
