   i called fn_setDesc() but now there's an exception occurred in fn_setDesc()
   inc_Cust_Desc is a mx:TextArea
   ```
   dbzIncentiveSchemeSetup.prototype.dbzIncentiveSchemeSetup_fn_SetDesc = 
function() {
     this.inc_Cust_Desc.text = "";
     for (var /** @type {number} */ j = 0; j < 
this.inc_Cust_DescList.dataProvider.length; j++) {
       this.inc_Cust_Desc.text += this.inc_Cust_DescList.dataProvider[j] + "\r";
     }
   };
   ```
   this.inc_Cust_Desc is undefined and this.inc_Cust_Desc.text is throwing 
exception
