# Feature: #64535 - IRRE: Suppress and override useCombination warning via TCA settings {#feature-64535}

See [forge#64535](https://forge.typo3.org/issues/64535)

## Description {#description}

When using `useCombination=TRUE` there is always a FlashMessage warning displayed.
It is now possible to override the default warning message with a custom message or
to suppress the FlashMessage completely via TCA setting.

Example to suppress `useCombination` warning message:

```php
$GLOBALS['TCA']['tx_demo_domain_model_demoinline']['columns']['irre_records']['config'] = array(
	'foreign_types_combination' => array(
		'1' => array(
			'showitem' => 'title'
		)
	)
	'appearance' => array(
		'suppressCombinationWarning' => TRUE
		'useCombination' => TRUE
	)
)
```

Example to override `useCombination` warning message:

```php
$GLOBALS['TCA']['tx_demo_domain_model_demoinline']['columns']['irre_records']['config'] = array(
	'foreign_types_combination' => array(
		'1' => array(
			'showitem' => 'title'
		)
	)
	'appearance' => array(
		'overwriteCombinationWarningMessage' => 'LLL:EXT:demo/Resources/Private/Language/locallang_db.xlf:tx_demo_domain_model_demoinline.irre_records.useCombinationWarning'
		'useCombination' => TRUE
	)
)
```
