TYPO3 Core

Please post the relevant parts of your tca.php file here. What is the whole structure and how are these fields of type 'inline' nested there?
If you're using two IRRE fields on the same parent table to the same child table, this won't work (see #17434 for details).

here is the relevant part of the TCA

as you can see "tx_gv_allegati" is a common attachment record that i use in many other records.
both tx_gv_edifici and tx_gv_piani have it
the problem is that tx_gv_allegati has tx_gv_piani ... there come big errors in the IRRE management!

I did not test it, but in your tca.php the 'foreign_table_field' property is missing for tx_gv_piani.allegati_piano.

Changing your configuration to the following should work:

'allegati_piano' => Array (
  'exclude' => 1,
    'label' => 'LLL:EXT:gv/locallang_db.xml:tx_gv.allegati',
    'config' => Array (
    'type' => 'inline',
    'foreign_table' => 'tx_gv_allegati',
    'foreign_field' => 'uid_parente',
    <b>'foreign_table_field' => 'table_parente'</b>
    'maxitems' => 10,
  )
),

thank Oliver! it was it!!!!

so foreign_table_field is quite mandatory...

(the TCA manual is not that clear about IRRE configuration.. i know i spent much time on it :(

so this bug can be closed?

No, the fix would be to improve the documentation in doc_core_api and the irre_tutorial.

doc_core_api i meant... yes

(i didn't check irre_tutorial .. i think it would be better to improve well doc_core_ap)

yes this bug can be closed, thanks oliver

Resolved, no change required as requested by reporter.
