Hello, I tried it with `increment_field_names: 1' but only the constraint
violation in the 1st block gets recognized, while all subsequents
violations are silently ignored. So, if I had, say, 4 blocks generated by
the repeatable with an error in the 4th, this last wrong block data would
be written to the DB. Moreover, only the 1st block, which contains the
error is displayed.
With increment_field_names: 0 I get all errors recognized, but still only
the first block displayed. Should I maybe try to set default_model:
HashRef?
Greets,
