我正在尝试根据为第一个值选择的内容显示第二个选择方法。现在我需要为我正在制作的表格执行38次以上,但我想看看我是否可以先让它解决一个问题。这是我到目前为止在jsf页面上剪切的代码。其他38个问题的值都是相同的。我刚刚重新创建了这个项目,到目前为止,bean目前还是空的,但我知道我应该至少能够看到表单,这是我希望在添加值和代码之前我现在要做的事情。

以下是我使用此代码获取的错误代码:
第88行和第76列的/indexv2.xhtml父类不是复合组件或类型为ClientBehaviorHolder,类型为:javax.faces.component.UIViewRoot@13fcf10
引起: 第88行和第76列的javax.faces.view.facelets.TagException - /indexv2.xhtml父类不是复合组件或类型为ClientBehaviorHolder,类型为:javax.faces.component.UIViewRoot@13fcf10
答案 0 :(得分:1)
删除f:ajax
之外的h:selectOneMenu
。 h:form
不是ClientBehaviourHolder
,因此您无法在f:ajax
放置h:selectOneMenu
。你可以将它们放入f:ajax
。
panelGroup
,包含selectOneMenu
的参数,并保留<h:selectOneMenu value="#{qcFormBean.dlitcStickerValue}">
<f:selectItem itemValue="P" itemLabel="Pass or Not applicable" />
<f:selectItem itemValue="M" itemLabel="FAIL-Mechanical" />
<f:selectItem itemValue="E" itemLabel="FAIL-Electrical" />
<f:selectItem itemValue="C" itemLabel="FAIL-Cosmetic" />
<f:selectItem itemValue="S" itemLabel="FAIL-Software" />
<f:ajax event="change" execute="@this" render="perfbyDlitcSticker" />
</h:selectOneMenu>
es:
</b>
<小时/> EDIT2:使用以下代码替换
<br/>
与commandButton
之前的代码:
<h:panelGroup id="dliSticker">
<h:selectOneMenu value="#{qcFormBean.dlitcStickerValue}">
<f:selectItem itemValue="P" itemLabel="Pass or Not applicable" />
<f:selectItem itemValue="M" itemLabel="FAIL-Mechanical" />
<f:selectItem itemValue="E" itemLabel="FAIL-Electrical" />
<f:selectItem itemValue="C" itemLabel="FAIL-Cosmetic" />
<f:selectItem itemValue="S" itemLabel="FAIL-Software" />
<f:ajax event="change" execute="@this" render="perfbyDlitcSticker" />
</h:selectOneMenu>
</h:panelGroup>
<h:panelGroup id="perfbyDlitcSticker">
<h:selectOneMenu value="#{qcFormBean.stickerFreq}"
rendered="#{!qcFormBean.dliStickerValue eq 'P'}">
<f:selectItem itemValue="A" itemLabel="Always" />
<f:selectItem itemValue="O" itemLabel="Often" />
<f:selectItem itemValue="S" itemLabel="Seldom" />
</h:selectOneMenu>
</h:panelGroup>
答案 1 :(得分:0)
而不是使用'f:ajax'而是使用了richfaces'a4j:ajax'参数用于xhtml,而现在我有一个不同的问题“带有标签的网页不会只显示文本。”所以我无法确定我是否正确地转换为richfaces,但这是我改变的,如果我是对的,请告诉我。谢谢。
