Describe the bug / error

Hi there!
using SPFx v1.12.1 when you generate a field customizer and try to debug against a Choice field, onRenderCell never gets called. onInit works as expected.

When you change the field in the debug url pointing to single line of text or yes/no field, the event fires.

I'm testing this against AllItems.aspx of a 3 rows simple list with the default "Title" field and an added "Kind" choice field.
Thanks!

Steps to reproduce

1. setup a list with a choice field
2. create a field customizer with yo
3. just start the debugger against the choice field
4. set a breakpoint on onRenderCell and see that it never gets hit

Expected behavior

field customizer fires onRenderCell as it does for single line of text or yes/no fields

Thank you for reporting this issue. We will be triaging your incoming issue as soon as possible.

I just discovered that onRenderCell is called when the default "Choice Pill" column format is manually removed.
Does this mean that column formatting takes precedence over field customizer by design?

To repeat that back to you - you had custom formatting in the field (like JSON formatting), as well as a field customizer?

[AkumaTen]

yes I had. When you create a choice column, a "choice pill" json formatter is the default. Field customizer + json formatter have some odd behaviour. For example, you can hide column headers with json formatter and still have onRenderCell firing, but if you add a rowFormatter in the json formatter, onRenderCell is not called.
Furthermore, onRenderCell doesn't work with "gallery" view of the same list

Thanks for the additional information and feedback @AkumaTen . I'll close this as working as expected, but I'll also send the feedback to the list formatting / field formatting / owners.
