我已将PrimeFaces从5.1决赛升级到5.2决赛(社区发布).我有一个<p:dataTable>懒惰加载如下(一个最小的例子来重现问题仅用于纯测试目​​的).

<p:dataTable  var="row"
              value="#{testManagedBean}"
              lazy="true"
              editable="true"
              rowKey="#{row.fruitId}"
              selection="#{testManagedBean.selectedValues}"
              rows="50">

    <p:column selectionMode="multiple"/>

    <p:ajax event="rowEdit" listener="#{testManagedBean.onRowEdit}"/>

    <p:column headerText="Id">
        <h:outputText value="#{row.fruitId}"/>
    </p:column>

    <p:column headerText="Fruit Name">
        <p:cellEditor>
            <f:facet name="output">
                <h:outputText value="#{row.fruitName}"/>
            </f:facet>
            <f:facet name="input">
                <p:inputText value="#{row.fruitName}"/>
            </f:facet>
        </p:cellEditor>
    </p:column>

    <p:column headerText="Price">
        <p:cellEditor>
            <f:facet name="output">
                <h:outputText value="#{row.price}"/>
            </f:facet>
            <f:facet name="input">
                <p:inputText value="#{row.price}"/>
            </f:facet>
        </p:cellEditor>
    </p:column>

    <p:column headerText="Edit">
        <p:rowEditor/>
    </p:column>
</p:dataTable>

    private List<Fruit> selectedValues; // Getter & setter.
