dialog breaks on execute

Hi
please advise :
why does this dialog breaks when trying to execute ?
(the DLG_LINE is not related to the pages on purpose ...)

RESOURCE DIALOG r_dialog 
{ 
   title="r_dialog"; 
   buttons = r_buttons; 
   flags=EEikDialogFlagWait | EEikDialogFlagNoDrag; 
   pages = r_multipage_option_array; 
   items = 
   { 
      DLG_LINE 
      { 
       prompt="list"; 
         id=EId1; 
         type=EEikCtChoiceList; 
         control=CHOICELIST {maxdisplaychar=25;}; 
         itemflags = EEikDlgItemNoBorder | EEikDlgItemNonFocusing; 
      } 
   }; 
} 
RESOURCE ARRAY r_multipage_option_array 
{ 
 items = 
 { 
  PAGE 
  { 
   id = 1; 
   text = "tab1"; 
  }, 
  PAGE 
  { 
   id = 2; 
   text = "tab2"; 
  } 
 }; 
}
