Hi!

I posted the following message to the struts-user group yesterday.
I searched jGuru, the internet, but couldn't find a solution.
Maybe you can help me?

Version is Struts 1.0 release, running on J2EE 1.3.1 (standard server).

-----8<-----

I absolutely have no idea what could be wrong. It's all coded as defined in
the tag lib docs.

in my jsp:

<logic:iterate id="current" name="theKeynameMap" property="keynameMap">
    <tr>
        <td><bean:write name="current" property="key"/></td>
        <td><html:text name="current" property="value"/></td>
    </tr>
</logic:iterate>

theKeynameMap is a form bean with a property keynameMap. Here are the
relevant lines:

public class KeynameMapForm extends ActionForm {

    protected Map theKeynameMap = new HashMap();

    public Map getKeynameMap() {
        return theKeynameMap;
    }

    public void setKeynameMap(Map keynameMap) {
        this.theKeynameMap = new HashMap(keynameMap);
    }

}

In the map, both key and value are simple strings.

And finally, the exception:
