ui:repeat内的复选框未由Ajax刷新 [英] Checkbox inside ui:repeat not refreshed by Ajax
问题描述
我使用Mojarra 2.1.3.
I work with Mojarra 2.1.3.
当用户单击刷新不起作用"按钮时,它将刷新ui:repeat的内容.我希望选中该复选框,就像在初始化时一样.
When the user click on button "refresh don't work", it refresh the content of the ui:repeat.I expect the checkbox to be checked, just as at the initialization.
我发现的结果:如果我删除了小面中的h:head,则刷新不起作用"有效...知道吗?
What I've found: If I remove h:head in the facelet "refresh don't work" works... Any idea ?
方面:
<h:head></h:head>
<h:body>
<h:form id="myForm" >
<h:panelGroup id="panelToRefreshOutsideRepeat">
<ui:repeat value="#{sandbox.columns}" var="column">
<h:panelGroup id="panelToRefreshInsideRepeat">
<h2>composite onlyCheckbox:</h2>
<trc:onlyCheckbox value="#{column.value}" />
<br />
<h2>composite onlyInputText:</h2>
<trc:onlyInputText value="#{column.value}" />
<br />
<br/>
<h:commandButton value="Refresh don't work" >
<f:ajax render="panelToRefreshInsideRepeat" />
</h:commandButton>
<h:commandButton value="Refresh work" >
<f:ajax render=":myForm:panelToRefreshOutsideRepeat" />
</h:commandButton>
</h:panelGroup>
<br/>
</ui:repeat>
</h:panelGroup>
onlyCheckbox和onlyInputText的组合:
The composite for onlyCheckbox and onlyInputText:
<composite:interface>
<composite:attribute name="value"
type="boolean"/>
</composite:interface>
<composite:implementation>
boolean: <h:selectBooleanCheckbox value="#{cc.attrs.value}" />
<!-- for onlyInputText h:inputText instead of h:selectBooleanCheckbox -->
boolean value: #{cc.attrs.value}
</composite:implementation>
和辅助bean:
@ManagedBean
@RequestScoped
public class Sandbox {
public List<Column> columns = Arrays.asList(new Column(true));
public List<Column> getColumns() {
return columns;
}
public void setColumns(List<Column> columns) {
this.columns = columns;
}
public class Column {
private boolean value;
public Column(boolean value) {
this.value = value;
}
public void setValue(boolean value) {
this.value = value;
}
public boolean getValue() {
return this.value;
}
}
}
推荐答案
即使在最新的Mojarra 2.1.4上,我也可以重现您的问题.如果该复选框不在复合材料内部,则效果很好.这是Mojarra的<ui:repeat>
中的错误.它是 MyFaces 2.1.3 上可以正常工作.
I can reproduce your problem even on latest Mojarra 2.1.4. It works fine if the checkbox is not inside a composite. This is a bug in Mojarra's <ui:repeat>
. It is totally broken in Mojarra. It works perfectly fine on MyFaces 2.1.3.
您有2个选择:
- 用MyFaces代替Mojarra.
- 使用
UIData
组件代替<ui:repeat>
,例如<h:dataTable>
,<t:dataList>
,<p:dataList>
等
- Replace Mojarra by MyFaces.
- Use an
UIData
component instead of<ui:repeat>
, e.g.<h:dataTable>
,<t:dataList>
,<p:dataList>
, etc.
