数据表中的单元格编辑器在JSF中只获取一个值

Question

我试图使用选择模式从数据表中选择一些项目，并指定我使用CellEditor选择的项目数量，但CellEditor没有获得我单击"显示"按钮后输入的所有值，它只获得我在CellEditor的列中输入的最后一个值。拜托，我需要有人来帮我!!

My XHTML code

<p:dataTable  editable="true"  editMode="cell"  id="change" selection="#{openJobOrderBean.selectedMaterials}"  rowKey="#{openJob.materialId}"
              rows="5" var="openJob" value="#{openJobOrderBean.smtOrder}" paginator="true" paginatorPosition="bottom"
              paginatorTemplate="{CurrentPageReport} {FirstPageLink} {PreviousPageLink} {PageLinks} {NextPageLink} {LastPageLink} {RowsPerPageDropdown}"
              rowsPerPageTemplate="5,10,15">
    <p:ajax immediate="true" process="@this" event="cellEdit" listener="#{openJobOrderBean.onCellEdit}" update="change" />
    <p:column selectionMode="multiple" style="text-align: center; width: 80px" headerText="Select Requested Materials" />
    <p:column headerText="Quantity Requested(click to edit)" style="width: 150px; text-align: center" class="columnedit" >
        <p:cellEditor>

这是点击SHOW按钮

之前的结果

这是选择并单击SHOW按钮后的结果

你为什么要这样做?

#{openJob.materialName} - #{openJobOrderBean.quantity}

要获得任务的数量，您必须更改为:

#{openJob.materialName} - #{openJob.quantity}

而且，这看起来真的很糟糕。不要存储bean的列表。为openJob创建一个实体类，并存储这些实体的列表。
