（JSF UI：PARAM）java.lang.IllegalArgumentException：无法解析参数编号

Question

当我使用

<ui:include src="File.xhtml">
        <ui:param name="anexoTarefaBeanEspecializado" value="#{myBean}"/>
</ui:include>

而在“ File.xhtml”上的ui：composition中的这段代码

<t:saveState value="#{anexoTarefaBeanEspecializado.anexoTarefaSecao}" />

并且myBean具有填充有getter和setter的属性“ anexoTarefaSecao”。

然后我向该页面发出请求，它已正确加载。 但是当我在页面另一部分的按钮中提出请求时，我得到了这种期望：

Answer 1

此错误消息尚不清楚。 但是通常，如果未正确传递saveState上使用的参数，则会发生此错误。
