Question

<h:selectBooleanCheckbox />

will render a html checkbox.

How do I add a custom attribute ‘myAttribute’ with value 6 to it so that the result will be:

<input type="checkbox" data-myAttribute="6" ... />

Answer 1

There is no trivial way to achieve this. Unregistered attribtues are completely ignored. Assuming that you’re using Mojarra, your best bet is to extend Mojarra’s CheckboxRenderer with a custom one wherein you override the getEndTextToRender() method which writes the extra attribute. To get it to run, just register it in faces-config.xml as a renderer for component family javax.faces.SelectBoolean and renderer type javax.faces.Checkbox.

An alternative is to delegate the job to some onload JavaScript.
