Just for the record, the problem wasn't from the action to the jsp,
but from the submited action to load the data.
Continued trying and this was the thing that worked:

ResponseAction-conversion.properties:

Key_resp=java.lang.Long
Element_resp=java.lang.Double
CreateIfNull_resp=true

ResponseAction.java:
...
public class ResponseAction extends ActionSupport implements Preparable {
	protected Map<Long,Double> resp = new HashMap<Long,Double>();

	public void prepare() throws Exception {
...
	}
	
	public String save(){
...
}
	public Map<Long, Double> getResp() {
		return resp;
	}

	public void setResp(Map<Long, Double> resp) {
		this.resp = resp;
	}
}


detail.jsp:
...
<s:iterator value="metrics">
	<s:set id="description" value="description" />
	<s:set id="id" value="id" />
	<s:textfield name="resp[%{id}]" label="%{description}" value="" /><br/>
</s:iterator>

The trick was the Action-conversion.properties, so the framework can
convert to a proper value and populate it. Please note that you need
to specify the fully qualified class name, even on java.lang clases.
