DataTable rows disappear when using headerRow

[DaBe1812]

Hi,
I'm using Primefaces 14.0.3 and I have the issues with p:dataTable, when I'm using a p:headerRow and want to have editable="true".
Everything works fine, but if you edit a line it doesn't matter if I save or cancel the edit, the line always disappears. I only have to close and open it's headerRow and it reappears but this behavior can't be correct it must be some issue with the relöoad of the table after editing.

Please provide an executable example using the PrimeFaces Test project. It is the only way developers can debug your problem to help.

Hi, I've known that but I was to dumb t find the Test-Project again. You can find my code here
https://github.com/DaBe1812/primefaces-datatable-issue.git
When you start the server yu get a table with the artists as headerRows. By clicking on the change and commiting the change the line disappears and reappers by closing and opening the headerRow again.

I see. i am pretty sure Expandable Grouped header rows and editable rows was not designed to work together. Not all features of the datatable are designed to be used together.

But I could Imagine that it is only an issue with updating the table so it could be possible to make it work.

@Rapster what are you thoughts here? This almost works but not sure these two things were designed with each other in mind.

Some investigation is necessary to explain why these features are not compatible, but at first glance I'd say it's a bug
