> Key: TAP5-804
> URL: https://issues.apache.org/jira/browse/TAP5-804
> Project: Tapestry 5
> Issue Type: Bug
> Components: tapestry-core
> Affects Versions: 5.0.18
> Reporter: Paul Field
> Assignee: Josh Canfield

> When writing a mixin that uses Element#addClassName, I noticed that I was getting two 'class' attributes in my element - rather than the one I was expecting.
> I've narrowed the problem down to a problem with how namespaces are used in Element and the following test case shows the problem. The "actual" output is:
> <e class="a b" class="a" xmlns="http://www.w3.org/1999/xhtml"></e>
> --------------------------------------
> package test.com.db.fusion.iface.web.tapestry5.mixins;
> import junit.framework.TestCase;
> import org.apache.tapestry5.dom.DefaultMarkupModel;
> import org.apache.tapestry5.dom.Document;
> import org.apache.tapestry5.dom.Element;
> public class AddClassNameTest extends TestCase {
> public void test() {
> Document document = new Document(new DefaultMarkupModel());
> Element element = document.newRootElement("http://www.w3.org/1999/xhtml", "e");
> element.attribute("class", "a");
> element.addClassName("b");
> assertEquals("<e class=\"a b\" xmlns=\"http://www.w3.org/1999/xhtml\"></e>", element.toString());
> }
> }
