Wow... I have been meaning to look into the decorators, but dang that is 
pretty simple!

You can do this with a decorator.  I created my own ListWrapper.java
decorator class:

<snip>
public class ListWrapper extends TableDecorator {
 /**
  * Creates a new Wrapper decorator who's job is to reformat some of the
  * data located in our forms.
  */

 public ListWrapper() {
  super();
 }

 /**
  *  Returns an xhtml-compliant checkbox used to select multiple rows
  */
 public String getAssetBox() {
  AssetForm form = (AssetForm) this.getObject();
  String assetId = form.getAssetId();

  return "<input type=\"checkbox\" name=\"rowId\" value=\""
   + assetId
   + "\" />";
 }
}
</snip>

In my assetList.jsp:
<bean:struts id="searchURL" forward="searchAsset"/>


<html:form action="/assetEdit" styleId="assetForm">
<display:table name="assetResults" scope="request"
    requestURI="<%=request.getContextPath() + searchURL.getPath()%>"
    pagesize='<%=(String)session.getAttribute("pageSize")%>'
    decorator="com.raibledesigns.webapp.taglib.ListWrapper">
    <display:column property="assetBox" width="3%"
        title="<input type=\"checkbox\" name=\"allbox\"
onclick=\"checkAll(document.forms[0])\">"/>
   ... continue rest of columns

And the checkAll javascript function:

function checkAll(theForm) { // check all the checkboxes in the list
  for (var i=0;i<theForm.elements.length;i++) {
    var e = theForm.elements[i];
  var eName = e.name;
     if (eName != 'allbox' &&
            (e.type.indexOf("checkbox") == 0)) {
         e.checked = theForm.allbox.checked;
  }
 }
}

HTH,

Matt
