TYPO3 : stdWrap.editIcons in CONTENT for non-admin BE_USER? -

i make quick typo3 6.2 extension extension builder (i'm fe integrator) , display content of tables in fe typoscript :

10 =  content 10 {     table = tx_ensgue_domain_model_ue     select {     pidinlist = 41     selectfields = tx_ensgue_domain_model_ue.uid,tx_ensgue_domain_model_ue.syl_code,tx_ensgue_domain_model_ue.syl_titre     join = tx_ensgue_ue_sylperiode_mm on (tx_ensgue_ue_sylperiode_mm.uid_local = tx_ensgue_domain_model_ue.uid)     = (tx_ensgue_domain_model_ue.syl_titre '%%' , tx_ensgue_domain_model_ue.deleted=0)     andwhere = tx_ensgue_ue_sylperiode_mm.uid_foreign=1     orderby = tx_ensgue_domain_model_ue.syl_code     }      renderobj = coa     renderobj {      20 = text     20 {             field = syl_code             notrimwrap=|[|] |     }     30 = text     30 {             field = syl_titre     stdwrap.editicons = tx_ensgue_domain_model_ue:syl_code,syl_titre,syl_periode,syl_responsables     stdwrap.editicons.beforelasttag = 1     stdwrap.editicons.icontitle = modifier l'ue     required = 1 }     wrap = <li > |</li >     }      stdwrap {         wrap = <h2>semestre 5</h2><ul class="syl_fe">|</ul>         required = 1     } } 

i try use feedit (from core) editicons availables admin users. non-admin can edit tt_content in page, won't work if display list of tt_content within content object. may hard coded in typo3/sysext/core/classes/frontendediting/frontendeditingcontroller.php (line 459 ?) it's beyond knowledge. how can use stdwrap.editicons allow non-admin be-users edit tables ?

i've been searching in core/classes/frontendediting/frontendeditingcontroller.php. in function allowedtoedit(), working when $mayedit = true; or $editaccessinternals = true; or $checkeditaccessinternals = false;

my problem in core/classes/authentication/backenduserauthentication.php (the checking languages part). checking $globals['tca'][$table]['ctrl']['languagefield'].

so replaced

$tca['tx_ensgue_domain_model_ue']['ctrl']['languagefield'] = 'sys_language_uid'; 

to

$tca['tx_ensgue_domain_model_ue']['ctrl']['languagefield'] = 0;  

in extension, , it's working.

i don't understand change because demo user had rights on languages, , config.sys_language_uid = 0 in setup ts...
