Are there any common pitfalls or mistakes to avoid when working with Checkbox elements in Zendframework 2?

One common pitfall when working with Checkbox elements in Zendframework 2 is not setting a default value for the checkbox element. This can lead to unexpected behavior if the checkbox is not initially checked or unchecked as expected. To avoid this, always set a default value for the checkbox element.

// Setting a default value for a Checkbox element in Zendframework 2
$checkbox = new Element\Checkbox('my_checkbox');
$checkbox->setValue(1); // Set default value to 1 (checked)
$checkbox->setChecked(true); // Check the checkbox by default
