[LiveComponent] Unable to detect which button was clicked

[toby-griffiths]

I've set up a LiveForm to perform live validation on our form, however I can't work out any way to detect which button the user has clicked, as the data coming through to the server is always null for the submitted data on any of the clicked or un-clicked buttons.

Am I doing something wrong, or is this a known limitation of the Live components?

I've also tried creating an custom type that renders <input type="submit" value="test"/> but this didn't work either.

It looks like it's the valueStore that is missing any values for the buttons, but I can't easily tell where this is updated from, or whether there's any way to modify the values before they're sent to the server.
