Grid: New line with required TextFields is not validated properly

[mirkoliver]

My Grid with TextFields as editors has some required columns. When editing and leaving required fields empty, it is not possible to leave the Editor - a validation error message is shown. This is the normal behaviour.

But after adding a new line in Grid via

itemList.add(new MyBean());
grid.getDataProvider().refreshAll();

and editing one or more field but also leaving one or more required fields empty, the Editor can be left without any error message.

Only if first I add to every field a value, leave the field (remaining in Editor) and then navigate back to one or more required fields and delete their values, the Editor cannot be left any more and the validation error messages occur.

Does this have to do something with these Vaadin github issues?

I'm using Vaadin Framework version 8.4.1.

Hello there!

We are sorry that this issue hasn't progressed lately. We are prioritizing issues by severity and the number of customers we expect are experiencing this and haven't gotten around to fix this issue yet.

There are a couple of things you could help to get things rolling on this issue (this is an automated message, so expect that some of these are already in use):

• Check if the issue is still valid for the latest version. There are dozens of duplicates in our issue tracker, so it is possible that the issue is already tackled. If it appears to be fixed, close the issue, otherwise report to the issue that it is still valid.
• 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.

Thanks again for your contributions! Even though we haven't been able to get this issue fixed, we hope you to report your findings and enhancement ideas in the future too!

Hi! ... I did some tests, and I see that is behaving correctly according to Tatu's explanation about this design decision.
