Symfony2 Sonata Admin shows text after creating a new item - php

Question

First, i'm sorry for my bad english,
im using sonata-admin bundle, and adminstrating my own Entity, when i'm creating a new item I have a block of text (the text that i write in the first input) that appears in the top of the Admin page, and it's ugly when its a big paragraph.
Lets say my first input is "Content", so when I write " This is my content " and save the item, it says "The item " This is my content" has been created succefully", how can I make another input be written in the success message
EDIT :
Here is a printscreen :
$formMapper
->add('page_mere1', 'choice', array('label' => 'Page mère 1', 'choices' => array('Podologie' => 'Podologie', 'Podz Pro'=>'Podz Pro')))
->add('page_mere2', 'choice', array('label' => 'Page mère 2', 'choices' => array('Pathologies' => 'Pathologies', 'Maladies spécifiques'=>'Maladies spécifiques')))
->add('page_mere3', 'choice', array('label' => 'Page mère 3', 'choices' => array('Pied' => 'Pied', 'Cheville'=>'Cheville', 'Jambe'=>'Jambe', 'Genou'=>'Genou', 'Hanche'=>'Hanche', 'Dos'=>'Dos')))
->add('translations', 'a2lix_translations_gedmo', array(
'translatable_class' => "Antipodes\SiteBundle\Entity\Pathologie",
'fields' => array(
'titre' => array(
'field_type' => null,
'required' => false,
'label' => 'Titre.',
'locale_options' => array(
'fr' => array(
'label' => 'Titre'
),
'en' => array(
'label' => 'Title'
)
)
),
'Definition' => array(
'field_type' => null,
'required' => false,
'label' => 'Definition.',
'locale_options' => array(
'fr' => array(
'label' => 'Definition'
),
'en' => array(
'label' => 'Definition'
)
)
),
)
))
;
//.......
Thanks in advance

I'm not sure if I'm understanding you correctly, but if you want to change the OK flashbag message after an successful edit you can do this with the _toString() method in your entity.
Open your Pathologie entity and add/edit the __toString() function, example:
public function __toString() {
return $this->titre;
}
The save-flashbag would then merge the "titre"-value instead of "Definition"-value into the message.
