        // Preview) because it would trigger the form validation which can prevent the switch (e.g. if the page title is
        // mandatory and it's not filled). We submit instead directly the edit form but this has the disadvantage that it
        // doesn't trigger the submit event so we may have form fields that are not up to date (e.g. because they use
        // widgets that update their value on submit). This is the case with the WYSIWYG editor that updates its hidden
        // fields for syntax conversion before the form is submitted. In order to overcome this we trigger an event to
        // let the form fields know that their values are about to be submitted. It makes sense to use the preview action
        // events because we don't want to save the content, we want to preview it in a different editor.
