Opening grid editor fails when a non-edited ComponentRenderer column returns null for that row

Describe the bug

I have a ComponentRenderer column that returns either a VaadinIcon.CLOCK.create(), a Div with some text, or null. When I click on a row (which also opens the editor) where this has value, everything is fine. When I click on a row where this is null, I get

13:43:55,264 ERROR [com.ptsmc.vaadin.CustomErrorHandler] (default task-26) Logged error: java.lang.NullPointerException: Cannot invoke "com.vaadin.flow.component.Component.getElement()" because "recreatedComponent" is null

    ...

When I change the ComponentRenderer to return an empty Div instead of null, it works.

Expected-behavior

No response

Reproduction

See description at top. I assume this is simply missing null-test and that the stacktrace is enough? If not I can try to produce an example

System Info

Windows 10, Vaadin 24.3.12, Firefox 127.0

Originally it was requirement that ComponentRenderer must not return null, but it was lifted by this PR: https://github.com/vaadin/flow-components/pull/4361/files

However it seems not to be complete.

Similar fix is needed in here: https://github.com/vaadin/flow/blob/main/flow-data/src/main/java/com/vaadin/flow/data/provider/AbstractComponentDataGenerator.java#L49

Same approach could be used,

if (recreatedComponent == null) {
   recreatedComponent = new Text("");
}

And if the fix is added in AbstractComponentDataGenerator, I would assume the fix in ComponentDataGenerator becomes redundant.

You seem to have found a corner case where flow is not going via ComponentDataGenerator ...

Just wanted to lift this again, I cannot reproduce it consistently, but for me this happens when I try to click a row in a grid to show the "details". I have a details renderer set on the grid with grid.setItemDetailsRenderer(new ComponentRenderer...)

Here's another stacktrace if it helps: Vaadin version 24.6.5
