Zoo Visitor + Radio button & Matrix fields + Inline error handling

Question

These don't seem to be playing very nicely together.

Here's what's happening:

I've got a Zoo Visitor registration form that contains generic member fields and well as a couple of required custom fields, of which, some are matrix and one is a radio button.

With inline error handling enabled, I'm seeing intermittent undefined index errors on submit within:

• matrix/ft.matrix.php :: line 1982 :: field_required
• radio/ft.radio.php :: line 131 :: field_pre_populate
• radio/ft.radio.php :: line 150 :: field_pre_field_id
• radio/ft.radio.php :: line 151 :: field_pre_channel_id

Field layout is as follows:

The matrix field is birthdate - 3 selects, all required. I know, I know... use a date field. Client req. But anyway... it should work. And it does sometimes. It has been addressed (sort of) by P&T and only errors out when the radio button following it is set to required.

The radio is gender, but it's not using the member field. And it's required.

At first, this seems obvious - the fields are set to pre-populate from another channel. But they're not. They're all set to 'n' and stored as such in the db and in the settings array. However, when validation runs and loops through settings, it's reading 'n' as NULL. So it errors out when it tries to query 'field_id_' on a null channel.

I'm at a loss here. And open to just about any ideas aside from defaulting everyone to M or F - which actually works when required.

Also - apologies if this is a repeat. I see a bunch of Q&A on related topics but nothing that quite matches my scenario.

From OP in comments above:

Just wanted to follow up and take credit for a simple mistake that monopolized more time than I'll ever admit. Turns out in my zoo form I had "new_row_0" in one of my hidden fields where it should have been "row_new_0".
