To fix this issue SIGH...Well I found out the solution.
I easily overlooked the WebFlow xml def file for the subflow and view state i was in.

code :

<view-state id="duplicate" view="duplicates">
    <transition on="continue" to="checkVehicleInfo" />
    <transition on="back" to="finished" />
</view-state>

model="customerModel"

I wish did fix the issue. So i finally solved it. The Problem was, that I used boolean instead of Boolean and my getter where named like isEnabled instead of getEnabled. This seemed to cause the problem with the mapping between the form element and the backing bean.

    List<UserType> userTypes = new ArrayList<>();
    for (long i = 0; i < userTypeService.count(); i++) {

    }
    for (UserType type : user.getUserTypes()) {
        userTypes.add(type.getId() - 1, type);

Spring Thymeleaf how to bind values of checkboxes to a collection field

By : Pastaru

around this issue I had to write my own Spring Converter to convert from "String" to "Role", mark that class as a @Component and create a @Bean. Then it worked like charm.

code :

@Component
public class StringRoleConverter implements Converter<String, Role> {

    @Override
    public Role convert(String source) {
        Role role = new Role();
        int id = Integer.parseInt(source);
        role.setId(id);
        return role;
    }

    @Bean
    public ConversionService getConversionService() {
        ConversionServiceFactoryBean bean = new ConversionServiceFactoryBean();
        Set<Converter> converters = new HashSet<>();
        converters.add(new StringRoleConverter());
        bean.setConverters(converters);
        return bean.getObject();
    }
}

it fixes the issue First at all, your checkbox must have a value field. In the java method to process this form, should be like:

code :

@RequestMapping("/attendance/createall")
public ResponseEntity<String> foo(@RequestParam("present") List<String> values) {

    //.....
}

Spring boot Thymeleaf and angularjs 1 - angularjs http request to spring controller not binding in thymeleaf view

will help you Thymeleaf was server-side rendering HTML, which mean the HTML page was rendered on the server before it shown on the browser. The other side, angularJS was designed to manipulate DOM from an exisiting HTML pages that already shown in the browser.
So, you can't use thymeleaf markup to shown data that manipulated by angularJS, instead you need to use with angularJS (I assume you want print $scope.responseData) like this:
