I am iterating over a MongoDB document.
where data is FindIterable.
<tr th:each="document, state : ${data}">
<td th:text="${state.count}"></td>
</tr>
state.last not working on iterable? why?
Instead of state.count if i use state.first it prints true for first element and false for all the rest.
When I use state.last it throws an exception.
Why can't I use state.last in this way?
Here is the Exception I got.
org.thymeleaf.exceptions.TemplateProcessingException: Exception evaluating SpringEL expression: "state.count + ' ' + state.last"

The error in the stack trace shows:
Property or field 'content' cannot be found on null
Which means you are trying to call content on something, but that something is null.
The only line in your Thymeleaf template that seems to match this is:
<div col="7" th:utext="${page.content}"></div>
So it means the page model attribute is null.
The controller puts stuff in the model, so we need to look there why this is null:
val page: Page?= pageRepository.findBySlug("home")
if (model != null) {
model.addAttribute("page",page)
}
My guess is that page is null here because there is nothing for slug home in your database?
this is my controller :
#GetMapping("/displayPieChart")
public String pieChart(Model model) {
model.addAttribute("pass", 50);
model.addAttribute("fail", 50);
return "pieChart";
}
and this the template that i'm using , i pass data from my controller as mentionned :
But i'm having this error :
here the stack :

I have a fragment of thymeleaf code with form. I want to validate this form.
<form>
<th:block th:fragment="input (label, name, type)">
<div class="col-md-3 form-group" th:class="${#fields.hasErrors(*{__${name}__})}
? 'col-md-3 form-group has-error' : 'col-md-3 form-group'">
Here I got exception:
Caused by: org.thymeleaf.exceptions.TemplateProcessingException: Exception evaluating SpringEL expression: "#fields.hasErrors(name)" (template: "fragments/inputFieldWithType" - line 5, col 42)
Caused by: java.lang.IllegalStateException: Neither BindingResult nor plain target object for bean name 'user' available as request attribute
As I seen in Baeldung, i have to bring field name in quotes like this:
${#fields.hasErrors('name')}
So how can I put name param into quotes?
You can use th:class="${#fields.hasErrors('__${fieldName}__')}"
I've 2 lists; allkontrols (2 element), risk.kontrols (1 element)
I'm listing all kontrols as checkbox and trying to 'select' them if risk.kontrols list contains it.
The one element in risk.kontrols is also in allkontrols.
So, when I tried to print the results of this:
<div th:each="kontrol : ${allkontrols}" th:text="${#lists.contains(risk.kontrols, kontrol)}"/>
I got results as
true
false
Everything is ok till here. Now, when I tried to populate them with data, I got errors. Here is the code:
<div th:each="kontrol : ${allkontrols}" class="items form-control-lg">
<label>
<input th:value="${kontrol.id}" th:selected="{#lists.contains(risk.kontrols, kontrol)}" type="checkbox" class="flat">
<div style="display: inline-block;" th:utext=" ${kontrol.name}"></div>
</label>
</div>
Error part:
th:selected="{#lists.contains(risk.kontrols, kontrol)}"

It looks like you're missing a $ before the { in your th:selected, try changing it to: th:selected="${#lists.contains(risk.kontrols, kontrol)}"
How can I display all rows from SQL database in JSP table?
In order to one row represent one 'td' tag in table. This code below displays only last row from my database.
CartController.java:
#RequestMapping(value="/cart.html", method = RequestMethod.GET)
public ModelAndView cartPage(Model model) throws SQLException, ClassNotFoundException {
PreparedStatement pst;
ResultSet rs;
Connection con;
con = db.getConnect();
pst = con.prepareStatement("SELECT * FROM onlineshop.cart");
rs = pst.executeQuery();
while (rs.next()) {
model.addAttribute("ID", rs.getString(1));
model.addAttribute("picture", rs.getString(2));
model.addAttribute("name", rs.getString(3));
model.addAttribute("company", rs.getString(4));
model.addAttribute("type", rs.getString(5));
model.addAttribute("price", rs.getString(6));
}
ModelAndView cart = new ModelAndView("Cart");
return cart;
}
and here is fragment of Cart.jsp:

note The full stack trace of the root cause is available in the Apache Tomcat/8.0.29 logs.
Because you're overriding cart information and obviously the last row wins the bet. You should maintain a List of Carts in your controller and push them to your view. Then in the view, iterate through them and put them in each row.
Suppose you have a Cart class like this:
public class Cart {
private String ID;
private String picture;
private String name;
private String company;
private String type;
private String price;
// getters and setters
}
Change your controller to create a List of Carts and add each Cart to the list:
...
List<Cart> carts = new ArrayList<>();
while (rs.next()) {
Cart cart = new Cart();
cart.setID(rs.getString(1));
cart.setPicture(rs.getString(2));
cart.setName(rs.getString(3));
cart.setCompany(rs.getString(4));
cart.setType(rs.getString(5));
cart.setPrice(rs.getString(6));
carts.add(cart);
}
model.addAttribute("carts", carts);
...
And in the view:
<%# taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>
...
<c:forEach var="cart" items="carts">
<tr>
<td>${cart.getID()}</td>
<td><img src="${cart.getPicture()}"/></td>
<td>${cart.getName()}</td>
<td>${cart.getCompany()}</td>
<td>${cart.getType()}</td>
<td>${cart.getPrice()}</td>
