[TYPO3-mvc] access to my fields in fe_users

[Ismaël Bidau]

Hi,
I've created an extension to add fields to fe_users (gender, birthday...)

Now, I want to create another extension to show my fe_users with 
extbase/fluid. I'm able to show all standard fe_users fields but not mine.

in Setup.txt
plugin.tx_ {
     persistence {
         classes {
             Tx_Parties_Domain... {
                 mapping {
                     tableName = fe_users
                 }
...

In my domain, I've add my fields :
protected $birthday;
function getBirthday() and setBirthday($birthday)

Any idea ? Order of loaded extensions ?

Thanks for your help.
