GWT: How to suppress hyperlink so that it doesn't change my history token

I want to make my hyperlinks act like buttons (only respond to Click event) however, they change the history token automatically when you click on them, which messes up my history mechanism in my application. Is there a way to suppress the default behaviour of the hyperlink so it doesn't change the history token? I tried setting targetHistoryToken to null but it didn't work.

Thanks,

Just remove href="" from Anchor.

<g:Anchor ui:field="clickField">Click here</g:Anchor>

Use Anchor instead.

As java doc of Hyperlink says:

If you want an HTML hyperlink ( tag) without interacting with the history system, use Anchor instead.

I created this class

import com.google.gwt.user.client.ui.HTML;

public class HyperlinkWithoutHistoryToken extends HTML {
    public HyperlinkWithoutHistoryToken(String html, boolean wordWrap) {
        super("<a href=\"javascript:undefined;\">" + html + "</a>", wordWrap);
    }
    public HyperlinkWithoutHistoryToken(String html) {
    super("<a href=\"javascript:undefined;\">" + html + "</a>");
    }
}

Like rustyshelf says,

final HTML contactLink = new HTML(""
          + contactName + "");
contactLink.addClickHandler(new ClickHandler() {
        public void onClick(ClickEvent event) {
  .....
 }
}

The easiest way by far to do this is to create your own class that extends Composite, and just renders an <a> </a> as a HTML widget. I had this same problem and that's how I got around it.
