Is there any way to change styleClass based on condition for primefaces components?

styleClass="#{(bean.comment==null) ? style1 : style2}"

You can do this, but it needs little modification. You should return string which represents class name:

styleClass="#{(bean.comment==null) ? 'style1' : 'style2'}"

Another approach is to calculate this condition in backing bean, and use simpler EL:

styleClass="#{bean.style}"

and in backing bean:

public String getStyle() {
  return (comment == null) ? "style1" : "style2";
}
