PPR On Radio Group

Steps to Create Properties View Object (PVO)

1.       Project à New ADF Business Components àView Object

2.       Specify the Name of View Object as XXTestPVO and give the corresponding package name

3.       Select Rows Populated Automatically Not Based on Query.

4.       Click Next after Step 3 , click on New and create the transient variables

5.       Create one attribute main_Attr of Type String

Select KeyAttribute ,passivate and Updatable always

6.       Create two other attributes display_rn1, display_rn2  of Type Boolean

Select Passivate and updatable always

7.       Click on Next , again Next , Select  Generate Java File , click on Next and then Finish

8.       Click on XXTestPVO and click on Tuning and select including all Transient Variables if it is not checked

9.       Now Attach it to PageAM 

Steps to implement PPR on Radio Group

1.       Create a Properties View Object (XXTestPVO) .create one Transient attribute (main_Attr) of String Type, Boolean Type Attributes as per requirement.(In Above case we created two display_rn1, display_rn2  )

2.       Since we are implementing PPR on a radiogroup item create a dummy VO

TO CREATE dummy VO Follow the below steps ;

i.                     Create a table using the following query : create table xxdummy (dummycol varchar2(30))

ii.                   Insert into xxdummy(‘abc’),insert into xxdummy(‘def’)

iii.                  Now use select dummycol from xxdummy as query and create VO , give the name as XXTestVO

iv.                 Attach it to pageAM

3.       Provide Itemname, ItemStyle, Picklist View Instance, Picklist Display Attribute , Picklist View Attribute ,Action, Event Name and parameters ,Rendered property for the item which you want to take do PPR in the Property Pallette.

Eg:

     Item Name: radGrpItm

   Item Style: MessageRadioGroup

 Picklist View Instance : XXTestVO1

Picklist Display Attribute: dummycol

Picklist View Attribute: dummycol

Action type : Fire Partial Action

     Event Name : PPREvt

     Under parameters

    Name : PPRParam

    Value : ${oa. XXTestPVO1. dummycol }

   RenderedProperty: ${oa. XXTestPVO1. main_Attr }

4.       In the Page Region 1 set Rendered as ${oa. XXTestPVO1. display_rn1 }

5.       In the Page Region 2 set rendered as ${oa. XXTestPVO1.display_rn2 }

Process Request of the CO :

      am.invokeMethod("initPPR");

Process Form Request of the CO:

     //Code for PPR

     if("PPREvt ".equals(pageContext.getParameter(OAWebBeanConstants.EVENT_PARAM)))

{

       String radioGroupValue = pageContext.getParameter("radGrpItm "); 

System.out.println("radio group value is :"+radioGroupValue);

   

    if(radioGroupValue!=null)

    {

    System.out.println("radioGroupValue is not null , going to AM method ");

    Serializable rgvS[]={radioGroupValue};

    System.out.println("serializable value of radio button passing to AM is :"+ rgvS);

    am.invokeMethod("execPPR", rgvS);

    System.out.println("back to Co after executing payePPR method in AM");

   

    }

     }

AMImpl

  public void initPPR ()

   {

     System.out.println("in initPPR ---am");

  

     OAViewObject pvo =

       (OAViewObject)findViewObject("XXTestPVO1");

    

     pvo.executeQuery();

    

     OAViewObject vo = (OAViewObject)findViewObject("XXTestPVO1");

     if (vo.getFetchedRowCount() == 0)

      vo.setMaxFetchSize(0);

     

     XXTestPVORowImpl pprrow= (     XXTestPVO RowImpl)vo.createRow();

     pprrow.setNewRowState(OARow.STATUS_INITIALIZED);

     vo.insertRow(pprrow);

 pprrow.setAttribute("main_Attr", Boolean.TRUE);

 pprrow.setAttribute("display_rn1", Boolean.TRUE);

pprrow.setAttribute("display_rn2", Boolean.FALSE);

   }

   public void execPPR(String param)

   {

     System.out.println("inside execPPR method with payee name :"+ param);

      OAViewObject vo = (OAViewObject)findViewObject("XXTestPVO1");

     if (vo.getFetchedRowCount() == 0)

      vo.setMaxFetchSize(0);

XXTestPVORowImpl pprrow= (XXTestPVORowImpl)vo.createRow();

vo.insertRow(pprrow);

     pprrow.setNewRowState(OARow.STATUS_INITIALIZED);

     

     if ("abc’".equals(param))

      {

      System.out.println("value is abc");

pprrow.setAttribute("main_Attr", Boolean.TRUE);

 pprrow.setAttribute("display_rn1", Boolean.TRUE);

pprrow.setAttribute("display_rn2", Boolean.FALSE);

      }

    else  if ("def".equals(param))

      

      {      

        System.out.println("value is def”);

pprrow.setAttribute("main_Attr", Boolean.TRUE);

 pprrow.setAttribute("display_rn1", Boolean.FALSE);

pprrow.setAttribute("display_rn2", Boolean.TRUE);

      }

   }
