Any way to "see" the Error object outside the page

I have a separate page for displaying the error information when a form
gets a validation error.
To be more precise, I use tiles and adds the error page at the top of the form page.
The problem is that the Error object only exists in the scope of the form
page. I don't want to include the error code in the form page because
I use css and this will cause problems with my layout.

In my "main" page I have this test:

<spring:hasBindErrors name="${param.form}">
<div class="error">
<tiles:get name="error"/>
</div>
</spring:hasBindErrors>

Where form is the form-bean which caused the error.
This test is working because the error page gets added,- but the Error
object is empty...

Here is my code (in the error page) for diplaying the errors:

<c:out value="${errors.errorCount}"/> # errors:
<ul>
<c:forEach var="errMsgObj" items="${errors.allErrors}">
<li><spring:message code="${errMsgObj.code}" text="${errMsgObj.defaultMessage}"/>
</c:forEach>
</ul>
