`appendTo="@(body)"` is missing for your `p:overlayPanel`.

That would definitively work. Another workaround could be to wrap the contents of the overlay in an `h:panelGroup` and update that instead of the whole Overlay Panel. A long term...

Additionally I recognized, that `setRowIndex` is used multiple times in e.g `DataTableRenderer#encodeRows`: line 1152,1157,1160,1164,1168; 1159,1167 (both because of isInSameGroup). I don't measured the performance overhead, but some of them could...

The question is, how to fix that behaviour. It is not totally wrong, as facets could be per-row. But most facets like header, footer, filter are not per-row. Easiest solution...

Well, the sample (kind of..) is provided in the **expected behavior** section :D But here you go: https://github.com/fanste/primefaces-test/tree/test-5649

I have no idea, why the reproducer was not available anymore... I pushed it again to the [same address](https://github.com/fanste/primefaces-test/tree/test-5649) and upgraded it to `-SNAPSHOT` available on Jitpack. The behavior of...

I'm a bit confused, as my reproducer behaves differently from the real application. My application works, but duplicates the components, but only once. The reproducer throws a duplicate-ID exception. When...

Added a reproducer. I just ignored that behavior, as a fix is more important ;) PR is also available: https://github.com/primefaces/primefaces/pull/9191
