上下文菜单和过滤器问题

Question

我试图在我的页面中同时使用上下文菜单和过滤器，但是在我过滤并重新加载页面后我得到了这个异常

启用选择后，DataModel 必须实现 org.primefaces.model.SelectableDataModel。

        <p:dataTable
        id="wtmInbox"
        rendered="#{flowDashboardManagedBean.renderOnLoadForWtm}"
        value="#{flowDashboardManagedBean.worktimematrixList}"
        var="wtms"
        stickyHeader="false"
        tableStyleClass="IEListTable"
        widgetVar="wtmInboxWidVar"
        scrollable="true"
        scrollHeight="700"
        editable="true" rowKey="#{wtms.worktimematrix.workTimeMatrixId}" selection="#{flowDashboardManagedBean.selectedWorktimematrix}" selectionMode="single">

        <p:ajax event="rowEdit" listener="#{flowDashboardManagedBean.onRowEdit}" update="wtmInbox"/>
        <p:ajax event="contextMenu" listener="#{flowDashboardManagedBean.onRowSelect}" ></p:ajax>

过滤器：

   <p:column headerText="#{bundle.status}"
                  sortBy="#{wtms.worktimematrix.workTimeMatrixStatus.name}"
                  filterBy="#{wtms.worktimematrix.workTimeMatrixStatus.name}"
                  filterMatchMode="exact"
                  style="text-align:right;"
                  priority="1"
                  width="10%">
            <p:cellEditor>
                <f:facet name="output">
                    <h:outputText value="#{wtms.worktimematrix.workTimeMatrixStatus}" converter="workTimeMatrixStatusConverter"></h:outputText>
                </f:facet>
                <f:facet name="input">
                    <p:selectOneMenu value="#{wtms.worktimematrix.workTimeMatrixStatus}" converter="workTimeMatrixStatusConverter">
                        <f:selectItem itemLabel="#{bundle.select}" itemValue="#{null}"/>
                        <f:selectItems value="#{flowDashboardManagedBean.workTimeMatrixStatuses}" var="worktimematrixStatus" itemValue="#{worktimematrixStatus}" itemLabel="#{worktimematrixStatus.name}"></f:selectItems>
                    </p:selectOneMenu>
                </f:facet>
            </p:cellEditor>

             <f:facet name="filter">
                <p:selectOneMenu onchange="PF('wtmInboxWidVar').filter()" id="flowModelTypeFilter">
                    <f:selectItem itemLabel="#{bundle.status}" itemValue="#{null}" noSelectionOption="true" />
                    <f:selectItems value="#{flowDashboardManagedBean.workTimeMatrixStatusNames}" var="status" itemValue="#{status}"/>
                </p:selectOneMenu>
            </f:facet>
        </p:column>

Answer 1

发现问题，table 背后的实体没有实现可序列化。在我添加过滤器后，当我在上下文菜单中添加时，它也起作用了。
