[TYPO3-irre] Cannot create more than 9 related records

[Mischa Heißmann]

On my new extension, IRRE shows a strange behaviour:

I can only create up to 9 related items in the sub-sub-relation.

Example:

Table.
    IRRE Element A
        IRRE Subelement 1
        IRRE Subelement 2
        IRRE Subelement 3
        IRRE Subelement 4
        IRRE Subelement 5
        IRRE Subelement 6
    IRRE Element B
        IRRE Subelement 7
        IRRE Subelement 8
        IRRE Subelement 9

No more IRRE Subelements are possible. If I delete one of them, I can create 
a new one.

My TCA:

for "Table":

  "tx_powermail_fieldsets" => Array(
   "label" => 
"LLL:EXT:powermail/locallang_db.xml:tx_powermail_forms.fieldsets",
   "config" => Array (
    "type" => "inline",
    "foreign_table" => "tx_powermail_fieldsets",
    "foreign_field" => "form",
    'foreign_sortby' => 'sorting',
    'foreign_label' => 'title',
    'maxitems' => 1000,
    'appearance' => Array(
     'collapseAll' => 1,
     'expandSingle' => 1,
     'useSortable' => 1,
     'newRecordLinkAddTitle' => 1,
     'newRecordLinkPosition' => 'both',
    ),
   )
  ),

for IRRE Element A:

  "fields" => Array(
   "label" => 
"LLL:EXT:powermail/locallang_db.xml:tx_powermail_fieldsets.fields",
   "config" => Array (
    "type" => "inline",
    "foreign_table" => "tx_powermail_fields",
    "foreign_field" => "fieldset",
    "maxitems" => 1000,
    'appearance' => Array(
     'collapseAll' => 1,
     'expandSingle' => 1,
     'useSortable' => 1,
     'newRecordLinkAddTitle' => 1,
     'newRecordLinkPosition' => 'both',
    ),
   )
  )


Some suggestions?
