  1. POError message is not displayed in freemarker template for custom FieldMatchValidator in Spring application
    text
    copied!<p>As stated in the title I can't make the error message for the FieldMatchValidator to show in my freemarker template. All the other "regular" error messages, such as <strong>@NotNull</strong> are displayed with the accurate message from message.properties. The validation with FieldMatchValidator works since the result.hasErrors() returns true and the result objects holds the FieldMatch error. What have I missed?</p> <p><strong>applicationContext.xml:</strong></p> <pre><code>&lt;!-- Invokes Spring MVC @Controller methods --&gt; &lt;bean class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter"&gt;
