Value change event with userOriginated true is sent when a DateTime is truncated

[jcgueriaud1]

In Vaadin 8.11, when you fill a DateTimeField with a LocaleDateTime a event is sent with userOriginated=true.

The behavior is not expected as the user didn't do any changes.

Here is the code to reproduce it:

        DateTimeField date = new DateTimeField("Date");
        date.setResolution(DateTimeResolution.SECOND);
        // don't throw value change listener
        //date.setValue(LocalDateTime.now().truncatedTo(ChronoUnit.SECONDS));
        // will throw a value change listener
        date.setValue(LocalDateTime.now());

        System.out.println(date.getValue());

        date.addValueChangeListener(event -> {
            if (event.isUserOriginated()) {
                System.out.println("From user " + event.getValue());
            } else {
                System.out.println("NOT From user " + event.getValue());
            }
        });

To avoid this value change event, you can truncate the value with the same resolution (here in second).

• Provide more details how to reproduce the issue.
• Explain why it is important to get this issue fixed and politely draw others attention to it e.g. via the forum or social media.
• Add a reduced test case about the issue, so it is easier for somebody to start working on a solution.
• Try fixing the issue yourself and create a pull request that contains the test case and/or a fix for it. Handling the pull requests is the top priority for the core team.
• If the issue is clearly a bug, use the Warranty in your Vaadin subscription to raise its priority.
