Updating grid field with radio field. Nope.

[jejuna]

We have several grid fields used in a fluid field. This site has been working perfectly for nearly 2 years.
Recently upgraded to EE 6.3.4. PHP is 8.02.

Now, anytime the client adds a row to an existing entry that has a radio fieldtype in a grid field, it won't save.

I thought it might be a corrupted entry, so I made a new one, and still, same error.

I made a new test grid field with a radio button in it, and still, same error.

It will save the first time with no issues. But adding a row to an existing grid field makes it bork.

I thought it might be an issue with the new conditional field, but I've checked, and none are marked conditional.

Here's the screenshot.

It's not just this field. It's every field that has a radio fieldtype.

This seems like a bug.

I have seen the same issue. Unclear what made it go away.

It's quirky to reproduce, but I am seeing the same thing. Let me see if I can spot why.

Annnnd now it's gone away and I can't trigger it again. But I definitely DID trigger it. I'm going to see if someone else has a better idea as to what's up.

Robin, any update on this? My client is concerned!

So, actually, it seems like it's not the radio buttons. It's more of a grid, that's a fluid field, that has an image in it. Adding a row is making it bork.

I might be having the same issue with File grid within fluid field. My set-up has been working for years, but recently (post EE6.3.3?) I can't add any new rows to the File grid, get the error "Cannot Update Entry". There's a message below the fluid field "There was a problem processing your submission, please check below and fix all errors." but nothing else is highlighted. Remove the new row, and I'll be able to save again. On EE 6.3.4 and PHP 8.0.13

Yep, that's me, too. The folks at EE do know about it.

I posted an issue that seems to be related to this here: #2145

As @jejuna sussed out, it's not related to the radio buttons, although when radio buttons (or another "grouped" field type) are involved, that's the only time you get any visual feedback, even though it's erroneous.
