IF DESG_OPT = 'U'.
UPDATE ZMSTR_DESIG
    SET DESG_DESC = DESG_DESC
    DESG_ACT = DESG_ACT
    WHERE DESG_CODE = DESG_CODE.
MESSAGE 'Updated Successfully' TYPE 'I'.
ELSEIF DESG_OPT = 'C'.
SELECT COUNT( * ) FROM ZMSTR_DESIG INTO CNT
   WHERE DESG_CODE = DESG_CODE.
   IF CNT > 0.
   MESSAGE 'Duplicate Designation code' TYPE 'I'.
   ELSE.
  WA-DESG_CODE = DESG_CODE.
  WA-DESG_DESC = DESG_DESC.
  WA-DESG_ACT = DESG_ACT.

My doubt is how to write code to insert data to table. I have written code like this.
try{
         String str1= wdContext.currentTestElement().getCode();
          String str2= wdContext.currentTestElement().getDesc();
          boolean str3= wdContext.currentTestElement().getAct();
          String str4= wdContext.currentTestElement().getOpt();
          String str5;
          if(str3)
          str5=new String("x");
          else
          str5=new String(" ");
          Zup_Desig12_Input input=new Zup_Desig12_Input();
          input.setDesg_Code(str1);
          input.setDesg_Desc(str2);
          input.setDesg_Act(str5);
          input.setDesg_Opt(str4);
          wdContext.nodeZup_Desig12_Input().bind(input);
          wdContext.currentZup_Desig12_InputElement().modelObject().execute();
    }catch(Exception e)
         wdComponentAPI.getMessageManager().reportSuccess(e.toString());
But i am getting      java.lang.ArrayIndexOutOfBoundsException: -1
in line
input.setDesg_Act(str5);
can any one help me plz
