我有按钮，当我点击它时，会出现对话框，在该对话框中，我有p:selectBooleanCheckBox和h:outputlable。
第一个问题是当p：对话框出现时我无法单独选择p:selectBooleanCheckBox。这意味着当我点击其中一个时，所有p:selectBooleanCheckBox都会选择。
第二个问题是当我在对话框中单击p:commandButton时，actionListener工作，但它不会令人失望并且会永久显示。我认为问题是由Ajax引起的。你能告诉我怎样才能解决这个问题？

答案 0 :(得分：0)
你的标记有点可怕，我不明白为什么你在<p:selectOneButton（所有<tr>）中有这么多东西所以不要试图纠正一切，因为我开始明白你想要达到的目标我会给你一个有效的例子。
Sample.java
public class Sample implements Serializable {
private String name;
private boolean checked;
public Sample() {
}
public Sample(String name, boolean checked) {
this.name = name;
this.checked = checked;
}
// Getter and Setter for name and checked omitted
}
SampleBean.java
@ManagedBean
@ViewScoped
public class SampleBean implements Serializable {
private List<Sample> samples;
private Sample currentSample;
public void prepareEdit(Sample sample) {
this.currentSample = sample;
}
public void edit() {
// Do what you need to do with sample
// You can get it with : this.currentSample
RequestContext.getCurrentInstance().execute("dlg.hide()");
}
public List<Sample> getSamples() {
if (this.samples == null) {
this.samples = new ArrayList<Sample>();
for (int i = 1; i <= 10; ++i) {
this.samples.add(new Sample("Sample n°" + i, (i % 3 == 0)));
}
}
return samples;
}
public void setSamples(List<Sample> samples) {
this.samples = samples;
}
public Sample getCurrentSample() {
return currentSample;
}
public void setCurrentSample(Sample currentSample) {
this.currentSample = currentSample;
}
}
view.xhtml：
<h:form id="myForm">
<p:dataTable value="#{sampleBean.samples}" var="sample">
<p:column headerText="Name">
<h:outputText value="#{sample.name}" />
</p:column>
<p:column headerText="Checked?">
<h:outputText value="#{sample.checked}" />
</p:column>
<p:column style="width: 1px; text-align: center;">
<p:commandButton value="edit"
actionListener="#{sampleBean.prepareEdit(sample)}"
update=":dialog"
oncomplete="dlg.show()" />
</p:column>
</p:dataTable>
</h:form>
<p:dialog id="dialog" widgetVar="dlg" header="Editing">
<h:form rendered="#{!empty sampleBean.currentSample}">
<h:outputText value="Current sample is #{sampleBean.currentSample.name}" />
<br />
<p:selectBooleanCheckbox value="#{sampleBean.currentSample.checked}" />
<br />
<p style="width: 100%; text-align: center;">
<p:commandButton actionListener="#{sampleBean.edit()}"
value="Edit"
update="@form :myForm" />
</p>
</h:form>
</p:dialog>
正如您所看到的，我正在存储currentSample（sampleBean 必须为@ViewScoped），这有助于我使用正确的当前内容呈现自定义对话框信息。
我关于<p:selectBooleanCheckbox绑定的问题的最后一条评论很重要，因为只有当它根据上下文（此处为currentSample）绑定到不同的端点时，才能获得自定义复选框值。
