I am trying to migrate my sample to the lates Spring Data R2dbc 1.0.0.RELEASE.

Schema.sql
CREATE TABLE IF NOT EXISTS posts (
id BIGINT NOT NULL AUTO_INCREMENT PRIMARY KEY,
title VARCHAR(255),

My initialziation codes failed.

this.databaseClient.insert()

.subscribe(null, null, () -> log.info("initialization is done..."));

There is an exception when the application is started.

The complete source codes is here. In the early version, I was using the jasync based r2dbc-mysql driver, it worked, but after I followed the official doc to use dev.miku:r2dbc-mysql at this time, it failed.
Resovled: Use the index instread of column name, see the comments in this issue

My form is working well, when I fill it out and press the "Save" Button it is stored in the database.
When I leave all fields empty and press "Save" nothing is happening and I get a 500 Error
An exception occurred while executing 'INSERT INTO members (username,
password, email, is_active) VALUES (?, ?, ?, ?)' with params ["",
null, "", "1"]:
SQLSTATE[23000]: Integrity constraint violation: 1048 Column
'password' cannot be null
This is actually fine, because the fields are required, but the errors are not displayed in my form, even if I added "required" = "true".
So when using the form builder, you have access to:
$form->isSubmitted()
and
$form->isValid()
As a result you can do something like:
if ($form->isSubmitted() && $form->isValid()) {
// save to database
}
We want to check the form is submitted before we check it's valid as if the form isn't submitted, it's unnecessary to check it's valid as it will be false.
This is going to prevent your MySQL error because your form technically isn't valid and you're trying to flush invalid data. We obviously only want to save our data when it's valid.
Of course, if the form fails you can return the view and in the template, you have access to
{{ form_errors() }}
This will probably cover what you need but you could also pass to your template something like
'formHasErrors' => $form->isSubmitted() && !$form->isValid(),
and then in your template
{% if formHasErrors %}
Something else you may want to do, this allows you to have more control over your fields, is separate out the field out like below:
{{ form_start(form) }}
{{ form_label(form.name) }}
{{ form_errors(form.name, {'attr': {'class': 'form-input'}}) }}
{{ form_widget(form.name) }}
{{ form_end(form) }}
It is very important you catch errors and handle them correctly. Your implementation didn't verify the form is valid which is why you were getting 500 errors.
I'm learning to programming and I'm trying to create in a page a list of booking that a user has done.
In particular, I would like to recover all the bookings made by a user using his email
I have create a JSP page:
<body>
<%=session.getAttribute("Nome") +" "+ session.getAttribute("Cognome") + " "+ session.getAttribute("Email") %>
<br>
Prenotazioni Effettuate:
<%
try{
String email=(String)session.getAttribute("Email");
// out.print("Hello "+n);
Class.forName("com.mysql.cj.jdbc.Driver");
// out.println("driver loaded");
Connection con = DriverManager.getConnection("jdbc:mysql://localhost:3306/Hotel","root" ,"123456789");
// out.println("Connect");
Statement stmt = con.createStatement();
// out.println("conncetion successfull");
String query="";
String emailp = "";
String arrivdate = "";
query="select * from reservation where email = "+email;
ResultSet r = stmt.executeQuery(query);
while (r.next())
{
emailp = r.getString("email");
arrivdate = r.getString("arrivalDate");
%>
Email: <%= emailp %>
Arrival date: <%= arrivdate %>
<% }}
catch(Exception e)
{
}
out.close();
%>
I don't understand why nothing is printed.
Is it a query problem or a code problem that's wrong? do you know how to help me?

I solved using this way:
String query="SELECT * FROM reservation WHERE email= '" + session.getAttribute("Email") + "'";
After submitting a form on the profile page it goes to the controller where it then updates a database to then redirect back to the same page that the form was on. However i get an error trying to return to the same page. I can however redirect to another page without any issues?
Any help would be great.
The Form
<form action="controller" method="post">
Link Name:<br>
<input type="text" name="createLinkName">
<br>
Link Content:<br>
<input type="text" name="createLinkContent">
<br>
<input type="hidden" name="command" value="createLink" />
<input type="submit" value="Submit">
</form>
Catching The Form Request
else if (command.equals("createLink"))
{
String linkName = request.getParameter("createLinkName");
String linkContent = request.getParameter("createLinkContent");
User sessionU = new User();
sessionU = (User)request.getSession().getAttribute("user");
int userID = sessionU.getId();
System.out.println(userID);
createLink(request, response, linkName, linkContent, userID);
}
createLink()
protected void createLink(HttpServletRequest request, HttpServletResponse response, String name, String content, int userID) throws IOException, ServletException
{
profileHandler ph = new profileHandler();
ph.createLink(request, response, name, content, userID);
request.getRequestDispatcher("profilePage.jsp").forward(request, response);
}
Handler that deals with the sql
public class profileHandler {
private final DatabaseManager dbMgr;
public profileHandler()
{
this.dbMgr = new DatabaseManager();
}
public void createLink(HttpServletRequest request, HttpServletResponse response, String name, String content, int userID)
{
dbMgr.establishConnection();
String CREATE_LINK = "INSERT INTO linkedaccounts (linkname, linkaddress, userid) VALUES ('" + name + "', '" + content + "', " + userID + ")";
dbMgr.prepareStatement(CREATE_LINK);
dbMgr.executePreparedStatement();
dbMgr.releaseConnection();
}
There isn't a problem with the sql as it is updated the Database just fine. Just wont allow me to eith stay on the same page as the form or just redirect back to it!
Thanks Again.

I would like to have a list of entries which I can shift/order and at the same time editable.
So I tought to combine p:orderList with p:inplace this way:
<p:scrollPanel style="width:300px;height:100px" scrollMode="native">
<p:orderList var="title" value="#{detailModel.afterObject.metadata.getTitlesAsList()}" type="definition">
<f:facet name="description">
<p:inplace id="basic" editor="true">
<p:inputText value="#{title.value}" required="true"/>
</p:inplace>
</f:facet>
</p:orderList>
</p:scrollPanel>
but I get the following error:
java.lang.NullPointerException

Do I miss something or it is not possible doing so?
If I use :dataList instead I don't get the error, but it has a strang behaviour; when I click on an entry, all the entries become editable, but then they remain in the edit-mode and nothing more is possibe...
Any suggestions?
EDIT
Here is the bean:
public class DoiDetailModel extends DetailModel
{
private List< String > selectedTitles;
private List< String > selectedCreators;
private String title;
private String creator;
public DoiDetailModel()
{
super();
}
public List< String > getSelectedTitles()
{
return selectedTitles;
}
public void setSelectedTitles( List< String > selectedTitles )
{
this.selectedTitles = selectedTitles;
}
}
EDIT: When renaming ProfileService.class to ProfileService2.class, it worked... Name clash somewhere?
When trying to deploy my application, I get the following exception:

As you can see, nothing is weird with ProfileService, just a very normal session bean. It's also worth to mention that I can still use the application, regardless of the exception.
What could be the cause?
Using JBoss 6 with Weld.
Seems like a bug in JBoss, Naming a class ProfileService was apparently not allowed. Renaming the class solved the problem.
