Liferay diaries: Help! My validation errors are not showing!

While still battling form submissions in my Liferay/Spring MVC Form controller/Multi-portlet beast, I noticed that the Spring form tags would not display errors. As this post [1] explains, the reason is that the form backing object must be named exactly as the class consituting the backing object, but with the first letter in lowercase.

Thus the jsp:

<form:form action="..." cssClass="acsform" commandName="searchDeliveryQuery">

must match the controller:

    public String view() {
        return "searchDeliveries";
