You need to have getters for jsp el expressions, it won't recognize public properties.
Change your MovieRecommendation class (and possibly others) to something like this:
#QueryResult
public class MovieRecommendation {
Movie movie;
int rating;
Movie getMovie() { .... }
int getRating() {....}

I am facing this strange behaviour whith Spring MVC and JSP where the ModelAttribute is sent to the JSP with populated fields but when it is returned to the controller all the fields are null.
So first of all I put an object as attribute in the model.
#PostMapping("qcm")
public String qcm(#ModelAttribute("qcm") Qcm formQcm, Model model) {
Qcm q = props.getQcm(formQcm.getDomaine(), formQcm.getMode());
model.addAttribute("qcm", q);
this.qcm = q;
return "qcm";
}
The ModelAttribute here works just fine. But note that I add a new attribute to the model here.
In the qcm.jsp page I display a form with some information from the qcm object I put in the model earlier. That means there is no way I send the fields of qcm as null in the first place.
Here is qcm.jsp:
<%# taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c"%>
<%# taglib prefix="form" uri="http://www.springframework.org/tags/form"%>
<!doctype html>
<html lang="en">
<head>
<meta charset="utf-8">
<meta name="viewport" content="width=device-width, initial-scale=1, shrink-to-fit=no">
</head>
<body>
<div class="container">
<h1 class="h3 mb-3 font-weight-normal">QCM</h1>
<form:form action="sendqcm" modelAttribute="qcm" method="POST">
<c:forEach var="question" items="${qcm.questions}">
<p>${question.data}?</p>
<c:forEach var="reponse" items="${question.reponses}">
<div class="form-check form-check-inline">
<form:radiobutton path="${question.chosenReponse}" value="${reponse}" label="${reponse.data}" class="form-check-input"/>
</div>
</c:forEach>
</c:forEach>
<input type="submit" value="envoyer" class="save" class="btn btn-lg btn-primary btn-block"/>
</form:form>
</div>
</body>
</html>
The informations are displayed just fine. I mapped the action to the sendqcm controller. Here it is:
#PostMapping("sendqcm")
public String sendqcm(#ModelAttribute("qcm") Qcm formQcm, Model model) {
System.out.println("Domaine -> " + formQcm.getDomaine());
System.out.println("Mode -> " + formQcm.getMode());
for(Question q : formQcm.getQuestions()) {
System.out.println(q.getChosenReponse());
}
for (Question q : formQcm.getQuestions()) {
if (q.answeredCorrectly())
score++;
}
model.addAttribute("score", score);
return "reponses";
}
The two lines of System.out.println() return null and then the program fails with NullPointerException:

You can add the #ControllerAdvice assists a controller and in particular, so #ModelAttribute methods that apply to all #RequestMapping methods.
I am not sure where the error is.

I got this resolved by setting the commandName attribute of the form to the name of the modelAttribute object used in my controller.
I also had to modify the method syntax to have BindingResult parameter which had to follow the ModelAttribute object.
public String ultimateBooking(#RequestParam("hotelId") String hotelId,#ModelAttribute("booking") Booking bookingValidation,BindingResult result,ModelMap model)
No changes were made to tile.xml

I try to configure spring with tiles and create a website - one to mane relation -> Klient - Pobyt and got a question regarding configuration.
I have got a class Klient and a class Pobyt, I also set up a view, but I am getting a null pointer exception when using = ${klient.idKlienta} in order to connect a klient to a list of pobyt`s.
I am getting a org.postgresql.util.PSQLException:- Error in postgresSQL syntax.
Using a concrete value in sql works fine.
Any idea what is wrong?

I tried to search for logs and what I have found is:

In Pg_log I have found what I`ve already posted:
2014-02-22 18:43:36 CET error syntax error at end of input (Position 44)
2014-02-22 18:43:36 CET Query:
SELECT * from Pobyt
where idKlienta =
So the problem is the idKlienta is not passed to the query? How can I solve it?
Can someone please point me to the right direction, it is a very simple spring form that I'm trying to edit. I have tried various examples from net but can not get it working.
<form:form id="myForm" modelAttribute="contacts" method="Post" action="contacts.html" commandName="contacts">
<label>First Name<span class="small">Edit your first name</span></label>
<form:input path="firstName" /><br>
<form:errors path="firstName" cssClass="error" /><br>
<label>Last Name<span class="small">Edit your last name</span></label>
<form:input path="lastName" /><br>
<form:errors path="lastName" cssClass="error" /><br>
<button type="submit">Amend</button>
</form:form>
protected static final String EDIT_VIEW_KEY = "editForm";
#Autowired
private ContactsService conService;
#RequestMapping(value="/edit/{id}", method = RequestMethod.GET)
public String showEditForm(#PathVariable("id") Integer id,
#ModelAttribute("contacts") Contacts contacts,Model model){
model.addAttribute("contacts", conService.listContactsById(id));
return EDIT_VIEW_KEY;
}
and the error I'm getting is this;
org.springframework.beans.NotReadablePropertyException: Invalid property 'firstName' of bean class [java.util.ArrayList]: Bean property 'firstName' is not readable or has an invalid getter method: Does the return type of the getter match the parameter type of the setter?

Many thanks
You're passing back a list to your form:
Invalid property 'firstName' of bean class [java.util.ArrayList]
Your form expects things like a firstName field.
In general, a list won't have a firstName field, although they might contain a collection of objects that have a firstName field. Did you mean to iterate over the list with a form per item?
you are using modelAttribute="contacts" in form and I think that contacts is ArrayList so it is not contains firstName, if your list have object of bean contains "firstName" you can use to iterate on it or use modelAttribute="contacts[${i}]" and set i using with the value you want.
