I want to fire an event change listener when the user selects / deselects something in the h:selectManyCheckbox, if it leaves it alone nothing should happen.

I get an error saying "One or more resources have the target of 'head', but no 'head' component has been defined within the view." I have < h:head> not just < head>, I read that this was a possible problem.
And the snippet from the bean:
public void changeListener(ValueChangeEvent e) {
change = true;
}
I have tried without < f:ajax like
<h:selectManyCheckbox
value="#{gridPopUpBean.oneQuestionUserAnswers}" valueChangeListener="#{gridPopUpBean.changeListener()}" onclick="submit()"
layout="pageDirection">
<f:selectItem itemValue="a"
itemLabel="#{gridPopUpBean.currentQuestion.a}" />
<f:selectItem itemValue="b"
itemLabel="#{gridPopUpBean.currentQuestion.b}" />
<f:selectItem itemValue="c"
itemLabel="#{gridPopUpBean.currentQuestion.c}" />
<f:ajax event="click" listener="#{gridPopUpBean.changeListener()}"/>
</h:selectManyCheckbox>
but with no luck...
Anything outside
<ui:composition>is ignored. If you need a<h:head>, it needs to go in the master template, thegridsTemplate.xhtml(or any of its parent templates).Further, if you aren't using a visual editor for your XHTML files (like Dreamweaver), then I strongly recommend to stop putting any content outside
<ui:composition>, otherwise you keep confusing yourself.See also:
You're confusing
valueChangeListenerwith<f:ajax listener>. TheValueChangeEventargument is only applicable tovalueChangeListenerattribute of anUIInputcomponent. Get rid of that argument.See also:
Unrelated to the concrete problem, you correctly used
click(although you could safely omit it altogether), but your question title mentionschangeand that is indeed the wrong event for a checkbox and radio button.See also:
