请这是非常重要我遇到了大麻烦，我试图解决它4天前没有成功。 我有一个使用cellEdit的主要面孔DataTable 但是当我尝试获取值时，它会在我更改之前得到相同的值。

答案 0 :(得分：0)
您想在什么情况下提交？ 我看到你最后有一个未贴上的标签，这是正常的吗？
如果要使用修改后的值更新managedBean，则需要某种方法告诉ManagedBean您要更新它。常规的InputText不会从前端到ManagedBean执行dataBinding。
执行此操作的一种方法是使用表单。
在提交时，表单内的InputFields的值将在后端更新。因此，在您的情况下，您需要将dataTable放在一个包含要提交的按钮的表单中，例如：
<h:form >
<p:commandButton value="OK" type="Submit" actionListener="#{programmeBean.click}" update=":content:cld:data1" />
<p:dataTable>
YOUR DATABLE....
</p:dataTable>
</h:form>
