p:outputLabel将为相关的UIInput设置标签,但是当它是Omnifaces的孩子时o:tree它不起作用。验证错误消息仍然使用clientId。
Omnifaces outputLabel可以为相关的UIComponent设置标签,它可以与o:tree一起使用。
Primefaces在endEncode方法中设置标签,当使用o:tree时,在endEncode之前调用validateValue方法。
任何人都有解决方法吗?
版本:
只能使用myfaces重现,使用Mojarra,最后一个节点中的标签值将用于其他节点的无效消息。
答案 0 :(得分:2)
我可以重现你的问题。此问题与OmniFaces <o:tree>
无关,但它实际上是PrimeFaces <p:outputLabel>
中的错误。作为证据,尝试在<ui:repeat>
中使用它,您会看到完全相同的问题出现。
至于它为何与OmniFaces <o:outputLabel>
一起使用,那是因为它在相关的输入组件中将标签设置为ValueExpression
。 PrimeFaces设置了当前评估的值,该值在请求消息时不一定是正确的值。
我建议将其作为issue向PrimeFaces人员报告,并使用<ui:repeat>
进行演示。
答案 1 :(得分:0)
这个问题有两个部分。一个是在主要方面。它将评估值设置为UIInput的label属性,而不是ValueExpression。所以所有数据都使用相同的标签。
第二个是兼容性问题。 Myfaces 2.1.9是JSF2.1,需要Component
尊重VisitHint.SKIP_ITERATION
。 Omnifaces不支持它。这是Omnifaces的补丁。
