Expected behavior
Expected - no errors :)
Minimal reproducible example
code like this
ui.accessLater(() -> {
// internal logic
ui.push();
}, () -> {
}).run();
Can't find reproduce example - very rare exception
Versions
- Vaadin / Flow version: 24.3.10
- Java version: 21
- OS version: Windows 10 / Ubuntu
- Browser version (if applicable): Chrome
- Application Server (if applicable): Spring Boot 3.2.6 Tomcat
Do you have implemented a custom DataProvider or using callback methods for lazy data binding?
If so, could you show the relevant code?
Hello. I have big application in Vaadin Flow, but I'm always use built-in methods, in one case it's ListDataProvider but - collection type is CopyOnWriteArrayList (and there no random access to this Grid, and there an additional lock protection).
Also there an override for key mapper
grid.getDataCommunicator().getKeyMapper().setIdentifierGetter(RawConfigRow::getKeys); // its map<string, object>
Which is immutable map, and never change
I got a report from a production system about a very similar exception today. Unfortunately, no idea what leads to the problem or what code caused it. Looks like it happened during logout. Vaadin version 24.7.13:

Hello. I can confirm - it's not related to logout. I have administration tool with ~100 concurrent users, we never do logout, but catch this issue periodically.
@VISTALL my comment about logout was not meant to indicate that the error is always somehow connected to the logout process, but rather that in my case, the exception happened while processing a logout process - meaning that it does not have to be connected to a particular UI related action (like using a custom Data Provider, using text field etc.), but that it can happen any time
