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);
}
}
