Struts 7.0.0 problem with s:property tag and beans

I am trying to migrate a project from Struts 2.3.x to 7.0.0, but I am having trouble retrieving attribute values from a bean using the <s:property> tag.

At first, I thought I was missing some configuration, but then I modified the Struts Sitemesh example text, and the problem persisted.

Struts.xml

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE struts PUBLIC
        "-//Apache Software Foundation//DTD Struts Configuration 6.0//EN"
        "https://struts.apache.org/dtds/struts-6.0.dtd">
<struts>
    <constant name="struts.devMode" value="true"/>
    <constant name="struts.ui.theme" value="simple"/>
    <constant name="struts.action.extension" value=""/>
    <constant name="struts.custom.i18n.resources" value="DefaultMessages"/>

    <package name="default" extends="struts-default">
        <default-action-ref name="index"/>
        <action name="index">
            <result>/WEB-INF/index.jsp</result>
        </action>

        <action name="hello" class="org.apache.struts.examples.sitemesh3.HelloAction">
            <result name="success">/WEB-INF/hello1.jsp</result>
            <result name="other">/WEB-INF/hello2.jsp</result>
            <result name="error">/WEB-INF/error.jsp</result>
        </action>

    </package>
</struts>

**HelloBean **

package org.apache.struts.examples.sitemesh3;


public class HelloBean {
    
    private int numero;
    private String valor;

    public HelloBean(int numero, String valor) {
        this.numero = numero;
        this.valor = valor;
    }

    @Override
    public String toString() {
        return "HelloBean{" + "numero=" + numero + ", valor=" + valor + '}';
    }
    
    

    public int getNumero() {
        return numero;
    }

    public void setNumero(int numero) {
        this.numero = numero;
    }

    public String getValor() {
        return valor;
    }

    public void setValor(String valor) {
        this.valor = valor;
    }
    
    
    
}

HelloAction

package org.apache.struts.examples.sitemesh3;

import org.apache.struts2.ActionSupport;
import org.apache.struts2.interceptor.parameter.StrutsParameter;

import java.util.Collections;
import java.util.Map;
import java.util.TreeMap;

public class HelloAction extends ActionSupport {
    
    public HelloBean hola = new HelloBean(1, "Hola mundo");

    private static final Map<String, String> DECORATORS = Collections.unmodifiableSortedMap(new TreeMap<>() {{
        put("1", "Decorator 1");
        put("2", "Decorator 2");
        put("3", "Exclude from decorating");
    }});

    private String decorator;

    @Override
    public String execute() throws Exception {
        if ("1".equals(decorator)) {
            return SUCCESS;
        } else if ("2".equals(decorator)) {
            return "other";
        }
        addActionError("Wrong decorator: " + decorator);
        return ERROR;
    }

    public String getDecorator() {
        return decorator;
    }

    @StrutsParameter
    public void setDecorator(String decorator) {
        this.decorator = decorator;
    }

    public Map<String, String> getDecorators() {
        return DECORATORS;
    }

    public HelloBean getHola() {
        return hola;
    }
    
    
}

You can add

<constant name="struts.allowlist.enable" value="false"/>

to the struts.xml. Or see Allowlist Capability
