Jsf 2 primefaces数据表行编辑器错误

我在Tomcat服务器上使用JSF2.2和PrimeFaces4.0以及Mojarra 2.2.2。 我使用带有行编辑器的p:datatable，但每当我尝试编辑一行时，按下“检查”按钮保存更改时会出现以下错误：

                    </p:column>
                </p:dataTable> 

最后一列是删除该行。它实际上工作得很好。 在上面的代码中，我用来迭代的列表是对象“Asociados”，它只是一个带有相应getter和setter的bean。

任何帮助都将不胜感激，提前感谢。

可能会显示nuevaInscripcionBacking类和nuevaInscripcionBacking.asociados变量？问题可能来自某个字段类型…例如，您将浮点输入到int类型或字符串到最新日期。类型不匹配HINGHOSEIN MASBOUND，谢谢您的回答。是的，我也这么认为，但所有字段都是字符串，我只输入字符串。我还注意到，当我删除datatable中的标记时，问题就消失了，我可以进行编辑correctly@HoseinMasbough非常感谢。我已经解决了这个问题。事实证明，我没有使用PrimeFaces4.0，而是使用了5.0快照，我必须下载快照才能添加图形。我下载了最新版本，即5.0。我看了一眼后意识到了这个错误
