XPages Managed Bean setter not firing on checkbox change

问题

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.

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;
}

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>

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

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

dataSource is set to use Methodbinding.

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.

thanks for any advice.

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));
}

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