Vaadin #Push with Vaadin4Spring Security - spring-boot

Question

Is anyone using Vaadin #Push with vaadin-spring-boot-starter and Vaadin4Spring Security extension?
Here is Vaadin related dependencies on our project:
compile 'com.vaadin:vaadin-client-compiled:7.5.8'
compile 'com.vaadin:vaadin-client:7.5.8'
compile 'com.vaadin:vaadin-themes:7.5.8'
compile 'com.vaadin:vaadin-server:7.5.8'
compile 'com.vaadin:vaadin-push:7.5.8'
// Official VaadinSpring Integration
compile("com.vaadin:vaadin-spring-boot-starter:1.0.0")
//Vaadin extentions - in the future more of those will go to official VaadinSpring Integration
compile("org.vaadin.spring.extensions:vaadin-spring-ext-security:0.0.6.RELEASE")
compile("org.vaadin.spring.extensions:vaadin-spring-ext-core:0.0.6.RELEASE")
compile("org.vaadin.spring.extensions:vaadin-spring-ext-boot:0.0.6.RELEASE")
compile("org.vaadin.spring.extensions:vaadin-spring-ext-test:0.0.6.RELEASE")
Here is the annotations on UI Class
#Theme("mytheme")
#Title(com.test.util.Constants.TITLE)
#EnableOAuth2Client
#SpringUI
#Push
public class MyVaadinUI extends UI {
...
}
And, Application.java ;
#EnableVaadinExtensions
#SpringBootApplication
#EnableConfigurationProperties
#EnableI18N
#EnableEventBus
#RestController
#EnableOAuth2Client
public class Application extends SpringBootServletInitializer {
public static void main(String[] args) {
SpringApplication.run(Application.class, args);
}
#Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
return application.sources(Application.class);
}
#Bean
public RequestContextListener requestContextListener(){
return new RequestContextListener();
}
#Bean
public FilterRegistrationBean hiddenHttpMethodFilter() {
HiddenHttpMethodFilter hiddenHttpMethodFilter = new HiddenHttpMethodFilter();
FilterRegistrationBean registrationBean = new FilterRegistrationBean();
registrationBean.setFilter(hiddenHttpMethodFilter);
return registrationBean;
}
#Bean(name = "messageSource")
public ResourceBundleMessageSource messageSource() {
ResourceBundleMessageSource messageSource = new ResourceBundleMessageSource();
messageSource.setBasename("messages/messages");
logger.debug("Returning messageSource: " + ((messageSource != null) ? messageSource.toString() : "NULL"));
return messageSource;
}
}
As soon as we call
security.login(username.getValue(), password.getValue());
(security is org.vaadin.spring.security.VaadinSecurity;)
we get the below exception;
16:36:35.272 [http-nio-8080-exec-9] ERROR c.b.g.c.s.v.views.login.LoginBox/login Login ERROR occured during login.org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'scopedTarget.httpService': Scope 'request' is not active for the current thread; consider defining a scoped proxy for this bean if you intend to refer to it from a singleton; nested exception is java.lang.IllegalStateException: No thread-bound request found: Are you referring to request attributes outside of an actual web request, or processing a request outside of the originally receiving thread? If you are actually operating within a web request and still receive this message, your code is probably running outside of DispatcherServlet/DispatcherPortlet: In this case, use RequestContextListener or RequestContextFilter to expose the current request.
I appreciate any help you can provide.

You are using Websockets, which do not use servlet requests and will not activate the "request" scope automatically.
If you use #Push(transport=WEBSOCKET_XHR) it should work, as the websockets channel will then be used only for server -> client pushes and standard HTTP requests will be used for client -> server messages.
