The method IF(boolean, String, String) is undefined for the type
SuiviExercice_1441008823562_230431 value = IF(((java.lang.String)field_libelle.getValue()).equals(""),String.valueOf(((java.lang.Double)field_octoberData.getValue()))+"%",String.valueOf(((java.lang.Double)field_octoberData.getValue()))); <>
