Spring MVC - <form:errors> empty, BindingResult contains errors

I am experiencing some issues with @Valid and BindingResult not pushing errors to the returned jsp page. The BindingResult in the method, detects binding errors correctly but the only way I can currently display errors is by manually adding result.getAllErrors() to the page. None of the following elements work:

<form:form name="updateForm" commandName="dataModel" method="post" action="${pageContext.request.contextPath}/pages/data">

    <form:errors path="*" />
    <form:errors />


    <c:forEach items="${dataModel.rows}" var="data" varStatus="currRow">
        <c:out value="${data.code}" />
        <form:errors path="dataRows[${currRow.index}].tolPercentage" />
        <form:input path="dataRows[${currRow.index}].tolPercentage" />
    </c:forEach>

</form:form>

Controller class method:

@Controller
@SessionAttributes("dataModel")
public class DataControllerController{

    @RequestMapping(value = "/data", method = RequestMethod.POST)
    protected ModelAndView onSubmit(
            @ModelAttribute("dataModel") @Valid DataModel dataModel ,
            BindingResult result
    ) throws ServletException, IOException {

        ModelAndView model = new ModelAndView("DataFormPage");

        if ( result.hasErrors() ) {
            model.addAllObjects(result.getModel());
        } else {
            ...
        }

        return model;
    }

    @ModelAttribute("dataModel")
    public DataModel getDataModel() {
        return new DataModel();
    }

}

Form field:

@Min(0)
@Max(1)
@Digits(fraction=2, integer = 1)
@Column(name="TOL_PERCENTAGE", precision = 1, scale = 2)
private BigDecimal tolPercentage;

I have looked through the majority of existing questions related to BindingResult and errors but none have worked.

Managed to fix this problem by switching on the Optimistic Serialization flag in the Weblogic 12c Console. Hope this will help others.
