我有我认为是一些简单的代码:
<ui:composition template="/templates/webflow.xhtml"
xmlns="http://www.w3.org/1999/xhtml"
xmlns:h="http://java.sun.com/jsf/html"
xmlns:ui="http://java.sun.com/jsf/facelets"
xmlns:p="http://primefaces.org/ui"
xmlns:f="http://java.sun.com/jsf/core">
<ui:define name="flowTitle">Page One</ui:define>
<ui:define name="pageTitle">Page 1 of 5: Please select a type</ui:define>
<ui:define name="content">
<h:form id="page1Form">
<div class="flow_main">
<div class="controls">
<p:selectOneRadio id="customRadio" value="#{flowState.selectedOption}" layout="custom">
<f:selectItem itemValue="-1" />
<f:selectItem itemValue="1" />
<f:selectItem itemValue="2" />
<f:selectItem itemValue="3" />
<f:selectItem itemValue="4" />
<f:selectItem itemValue="5" />
<f:selectItem itemValue="6" />
</p:selectOneRadio>
<!-- these to go into a datatable -->
<p:radioButton id="opt2" for=":page1Form:customRadio" itemIndex="1"/>
<p:radioButton id="opt3" for=":page1Form:customRadio" itemIndex="2"/>
<p:radioButton id="opt4" for=":page1Form:customRadio" itemIndex="3"/>
<p:radioButton id="opt5" for=":page1Form:customRadio" itemIndex="4"/>
<p:radioButton id="opt6" for=":page1Form:customRadio" itemIndex="5"/>
<p:radioButton id="opt1" for=":page1Form:customRadio" itemIndex="6"/>
</div>
</div>
<div style="text-align:right" class="flow_footer" >
<p:commandButton id="cancel" value="Cancel" ajax="true" action="cancel" onsuccess="javascript:parent.dlg.hide();"/>
<p:commandButton id="next" action="next" value="Next" onclick="return validate(1)" update="@form" />
</div>
</h:form>
</ui:define>
但是,在渲染时,底部的 3 个单选按钮被禁用。我尝试更改几乎所有属性以使其启用,但无济于事。
我设法使它们启用的唯一方法是添加以下行:
<h:inputHidden value="#{flowState.selectedOption}" id="hiddenId" />
即使这样也不能完全奏效;选择一个单选按钮并转到下一页正确绑定。但是,当我返回一个页面时,单选按钮再次被禁用!
