code

package com.example.demo;

import com.vaadin.flow.component.HasValue;
import com.vaadin.flow.component.orderedlayout.VerticalLayout;
import com.vaadin.flow.component.textfield.TextField;
import com.vaadin.flow.router.Route;

@Route(value = "test")
public class TestPage extends VerticalLayout {

    public TestPage() {
        setWidthFull();
        setHeightFull();
        TextField textField = new TextField();
        add(textField);
        textField.setWidthFull();
        HasValue<?, ?> hasValue = textField;
        hasValue.addValueChangeListener(event -> {
            System.out.println(event.getValue());
        });
    }

}

This code does not work if it was compiled using vscode. If you build the code using mvn clean package -DskipTests=true -Pproduction, the code will work.

main

package com.example.demo;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
public class DemoApplication {

    public static void main(String[] args) {
        SpringApplication.run(DemoApplication.class, args);
    }

}

This is an upstream jdt.core issue. A related bug - https://bugs.eclipse.org/bugs/show_bug.cgi?id=546161 A workaround:

package com.example.demo;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

import com.vaadin.flow.component.HasValue;
import com.vaadin.flow.component.HasValue.ValueChangeEvent;
import com.vaadin.flow.component.HasValue.ValueChangeListener;
import com.vaadin.flow.component.textfield.TextField;

@SpringBootApplication
public class DemoApplication {

    public static void main(String[] args) {
        TextField textField = new TextField();
        HasValue<?, ?> hasValue = textField;
        hasValue.addValueChangeListener((ValueChangeListener<ValueChangeEvent<?>>)event -> {
            System.out.println("change text value " + event.getValue());
        });
        SpringApplication.run(DemoApplication.class, args);
    }
