Spring Boot + Primefaces - "Unrecognized Content Type" Exception

Question

i have a basic setup using spring boot and joinfaces to use primefaces and bootsfaces in my application.

Using for example bootsfaces components and perform ajax calls works like a charm. When i add a simple primefaces component which uses ajax, the call fails and i get the following exception:

It does not matter if i just use a button like in this example:

<h:form>
   <p:commandButton value="Add" ajax="true" actionListener="#{pingResultBean.onAction}" />
</h:form>

or using any other primefaces component which fires ajax calls.

I have Spring security enabled and using following configuration:

http
        .authorizeRequests()
            .antMatchers("/login*").permitAll()
            .antMatchers("/logout*").permitAll()
            .antMatchers("/js/**").permitAll()
            .antMatchers("/css/**").permitAll()
            .antMatchers("/javax.faces.resource/**").permitAll()
            .anyRequest().authenticated()
        .and()
            .formLogin()
            .loginPage("/login.xhtml")
            .defaultSuccessUrl("/index.xhtml")
            .failureUrl("/login.xhtml?error=1")
        .and()
            .csrf().disable()
            .logout().logoutSuccessUrl("/login.xhtml?logout");

All other ajax calls are working. Would be nice if someone can help me.

Edited: Same error when i disable spring security.

The bug can easily be reproduces when cloning the official joinfaces starter https://github.com/joinfaces/joinfaces-gradle-jar-example

and add a primefaces button

Answer 1

I have the same setup and the same problem. It was caused by f:view tag in my main template.

<f:view contentType="text/html">

Removing it fixed the problem.

Answer 2

Exactly what Tom Bombadil say! If you had @this at the prossess property it will work! In my case, since I load menus from the database using the DefaultMenuModel, I have this:

DefaultMenuItem mi = new DefaultMenuItem();
mi.setValue(m.getDescription());
mi.setProcess("@this"); //IMPORTANT SINCE WILDFLY 14 - Unrecognized Content Type?!
mi.setIcon("id-icon-param");
if (m.isExecutecommand()) {
  mi.setCommand(m.getCommandinstruction());
} else if (m.isLoadasdialog()) {
  mi.setUrl(m.getViewId());
} 
mi.setUpdate("@form");
submenu.addElement(mi);

Hope it helps!
