How to show inital value in jsp form - spring

I am using jsp . And I just want to show a value (maxHolidays which is 15) in my form. But I always get exception Neither BindingResult nor plain target object for bean name 'command' available as request attribute
This is my code
Controller
int maxHolidays = 15;
model.addAttribute("maxHolidays", maxHolidays);
jsp File
<form:form method="POST" >
<div class="row">
<div class="col-lg-6">
<div class="form-group">
<div class="col-sm-10">
<label class="control-label">Max holiday length</label>
<form:input type="text" path="maxHolidays" id="maxHolidays"
class="form-control"
required="required" />
<div class="has-error">
<form:errors path="maxHolidays" class="help-inline" />
</div>
</div>
</div>
</div>
</div>
<div class="form-group">
<div class="col-sm-12">
<button type="submit" class="btn btn-success">Save</button>
</div>
</div>
</form:form>

try below code in jsp page
value="${maxHolidays}"

Try this
<div class="has-error">
<span class="help-inline">${maxHolidays}</span>
</div>

Are you adding "user" to your model in your controller?
You need to add it to your model so Thymeleaf can access it.
addAttribute method can be used like so: model.addAttribute("user", myUser);

Why is only one of these almost identical HTML-forms reacting to submit button click?

I have two almost identical forms. One is meant to edit an item, and the other is meant to create an item. For some reason, the create-form does not react at all to submit button clicks, while the edit/update form works exactly as expected. I can not find any differences between the two that should result in this behavior.
I am as sure as I can be that this has nothing to do with back end. I have monitored network activity, ant the submit button for the create-form does not activate any kind of network activity at all.
Working update form:
#extends ('layout')
#section('middle-content')

Partial view update on ajax POST redirecting to form's action method

I have created 2 partial views called _ftpsetupDetails.cshtml and _ftpsetupedit.cshtml
On load of the index page i am loading details partial view onto the below div.
now the problem is on post to the controller after save i am returning the ready only mode detail partial view. But instead of loading the partial view or hit done method of ajax it is redirecing the page to /FT/Edit url with detail partial view html on it. How to make sure the page is not redirected? what am i doing wrong?
//Once user clicks on Save button the below code will post the form data to controller
$(document).on("click", "#updateFTP", function () {
$.post("/Ftp/Edit", $('form').serialize())
.done(function (response) {
alert(response.responseText);
});
});
//On page load i am loading the partialview container witih read only view
LoadAjaxPage("/Ftp/DetailsByOrgId", "organizationId=" + orgId + "&orgType=" + orgType, "#ftpPartialViewContainer");
//On edit button click i am loading the same div container with edit partial view
$(document).on("click", "#editFTP", function () {
// $("#createUserPartialViewContainer").load("/Users/Create?organizationId=" + orgId + "&organizationType=" + orgTypeId);
LoadAjaxPage("/Ftp/Edit", "organizationId=" + orgId + "&orgType=" + orgType, "#ftpPartialViewContainer");
});

Displaying List entries as Checkboxes - Neither BindingResult nor plain available

I have the following object.
public class Anonymization {
#Id
#GeneratedValue(strategy = GenerationType.AUTO)
private long id;
#OneToMany(mappedBy = "anonymization")
private List<Host> hosts;
#OneToMany(mappedBy = "anonymization")
private List<Item> items;
The objects Host and Item have several boolean Fields. I want to display a form, where all Host and Item objects are displayed as checkboxes, so that the boolean fields can be edited. I wrote a controller to display the form
#RequestMapping("monitoringsystem/{mId}/anonymization")
public String editAnonymisatzion(Model model, #PathVariable Long mId){
model.addAttribute("mId", mId);
model.addAttribute("anonymization", monitoringSystemRepository.findOne(mId).getAnonymization());
return "monitoringsystem/anonymizationForm";
}
The anonymizationForm should display the checkboxes in a for-each-loop

<form class="form-horizontal" th:modelAttribute="anonymization" th:object="${anonymization}" th:action="#{'monitoringsystem/' + ${mId} + '/anonymisatzion/save'}" method="post">

Unfortunatly when i call the View I'm getting the following error
Caused by: java.lang.IllegalStateException: Neither BindingResult nor plain target object for bean name 'host' available as request attribute
I checkt my Database all Relationsships are set correctly. The List<Host> should contain 1 and the List<Item> 2 entries.
I can't find my mistake.
UPDATE 1:
I debuged the anonymization object which is passed to the form. It's is complete. Which means all listentries are present. So I guess the error has something to to do with my view - how I call the object.
I found the solution by myselfe. Fist of all i changes the way the list-objects are called in my form

Futhermore there seems to be a problem with the naming of the getter and setter. Mine were like:
setBoolean(boolean b){
this.b = b;
}
isBoolean(){
return b;
}
Spring or thymeleaf (i don't know which component is responsible) seems to need the getter starting with get. After changing this it's working now.
setBoolean(boolean b){
this.b = b;
}
getBoolean(){
return b;
}

jQuery FormValidation don't work inside of Bootstrap multi tab

I have a problem with FormValidation to validate a form in multi-tab (Bootstrap theme).When I click on submit button in #tab-1, formValidation work correctly. but when I change to #tab-2 or #tab-3, field validation in #tab-1 don't work and submit form without validation.
<form id="newstext" method="post" class="form-horizontal"

Please see my code in Codepen
This example might be helpful: formvalidation.io/examples/bootstrap-tab
JQuery FormValidation Has solved the problem Validation
That by replacing the jquery, validation between tabs work
You can add "ignore" in validate function, this worked fine with me
$("#form").validate({
...
rules: {...},
messages: {...},
ignore: "",
...
});
