TO ADD CUSTOM VALIDATORS IN ADF

TO ADD CUSTOM VALIDATORS IN ADF

The Code is tested on ADF 11.1.2.4.0 version.

Sometimes Business rule cannot be applied on Entity object to throw out error as per customer requirements.

We need to add custom validations to throw error during run time for an application.

Below code represents a scenario where I want to throw an error at run time if the Item quantity is in decimal point for particular Item UOM(Unit of measure) .

public void ValidatorReqQty(FacesContext facesContext,

                            UIComponent uIComponent, Object object) throws ValidatorException

{

DCBindingContainer bindings4 = (DCBindingContainer)BindingContext.getCurrent().getCurrentBindingsEntry();

DCIteratorBinding dcItteratorBindings = bindings4.findIteratorBinding("XXPRIVI_MATERIAL_REQUESTView1Iterator");

ViewObject XXPRIVI_MATERIAL_REQUESTView1 = dcItteratorBindings.getViewObject();

Row dv = XXPRIVI_MATERIAL_REQUESTView1.getCurrentRow();

       

            FacesContext fc = FacesContext.getCurrentInstance();

            BigDecimal ReqQuantityCurr  = (BigDecimal)object;

            System.out.println("ReqQuantityCurr" + ReqQuantityCurr);

           

String ReqQuantityCurrStr = (String)ReqQuantityCurr.toString();

System.out.println("ReqQuantityCurrStr" + ReqQuantityCurrStr);

           

String ReqQuantityCurrStrWithDec = (String)ReqQuantityCurr.setScale(2,BigDecimal.ROUND_UP).toString();

System.out.println("ReqQuantityCurrStrWithDec" + ReqQuantityCurrStrWithDec);

           

String DecnumberCurr = ReqQuantityCurrStrWithDec.substring(ReqQuantityCurrStrWithDec.indexOf(".")).substring(1);

System.out.println("DecnumberCurr" + DecnumberCurr  );

           

String CompareUom = "EA" ;

           

if(Uom.equals(CompareUom) && DecnumberCurr.compareTo("00") != 0)

     {

           throw new ValidatorException(new FacesMessage("Quantity cannot be in decimal for UOM 'EA'."));

      }

}

Now Run the project.

The below image represents the validation error as per the requirement.

 

Love ADF... :)
