XPage 托管 Bean setter 不会在复选框更改时触发 [英] XPages Managed Bean setter not firing on checkbox change

问题描述

我创建了一个自定义控件，它基本上是一个复选框.我希望复选框读取我传入的数据源的值 - 这将是一个托管 bean.我可以让复选框字段从 bean 中读取，但是当我更改复选框时我没有看到任何事情发生.看起来 bean 中的 setter 从未被调用过.

I've created a custom control that is basically a checkbox. I want the checkbox read the value of the dataSource I pass in - which would be a managed bean. I can get the checkbox field to read from the bean but I'm not seeing anything happen when I change the checkbox. It doesn't look like the setter in the bean ever gets called.

我的 bean 的关键片段是:

The key snippets of my bean are:

private boolean categoriesOn;
...

public boolean isCategoriesOn() {
    System.out.println("Getting On Value");
    return categoriesOn;
}
public void setCategoriesOn(boolean newValue) {
    System.out.println("Setting On : " + newValue);
    this.categoriesOn = newValue;
}

XPage 上的控件如下所示:

The control on the XPage looks like this:

<xp:checkBox id="flipSwitch"
                    styleClass="onoffswitch-checkbox"
                    value="${compositeData.dataSource}"
                    checkedValue="#{javascript:true}"
                    uncheckedValue="#{javascript:false}">
                    <xp:eventHandler event="onchange" submit="true"
                        refreshMode="complete">
                    </xp:eventHandler>
                </xp:checkBox>

我使用自定义属性将 bean 传递给自定义控件:

I pass the bean to the custom control with a custom property:

<xc:crtl_toggleSwitch
                dataSource="#{exhibitorInfo.categoriesOn}"
                refreshID="computedField6">
            </xc:crtl_toggleSwitch>

dataSource 设置为使用方法绑定.

dataSource is set to use Methodbinding.

我尝试了部分刷新和完全刷新.我只是不确定我需要做什么才能将更改后的值恢复到 bean 中.

I've tried with partial and full refresh. I'm just not sure what I need to do to get the changed value back into the bean.

感谢您的建议.

推荐答案

如 Peter 对 Per 链接到的问题的回答所示，复选框不能直接绑定到布尔值(这无疑是荒谬的).添加这些方法:

As indicated in Peter's answer on the question Per linked to, checkboxes cannot be bound directly to booleans (which is admittedly ridiculous). Add these methods:

public String getCategoriesOnAsString(){
 return isCategoriesOn() ? "1" : "0";
}

public void setCategoriesOnAsString(String value){
 setCategoriesOn("1".equals(value));
}

然后将您的复选框绑定到 #{exhibitorInfo.categoriesOnAsString}，并将 checkedValue 和 uncheckedValue 设置为 "1"和"0".

Then bind your checkbox to #{exhibitorInfo.categoriesOnAsString}, and set checkedValue and uncheckedValue to "1" and "0", respectively.
