Problem when I make Read Only Property True

Question

Dear Members,
I have an OAF Page on which I have the below two items:
1/ item1
2/ item2
These two items are message input text items and these two items will always have some value.
To meet one of my requirement, I am making the READ ONLY property of these two items to TRUE in processRequest method of page CO using PPR Concept. After this when I am trying to access the values of these two parameters in processFormRequest method using pageContext.getParameter method I am getting the Null Pointer Exception error.
Kindly please help me in resolving the above error.
Note: I have created a transient variable hdr1Trans and attached this variable to the both the items i.e., item1 & item2
Code in my processRequest method is as follows:_
public void processRequest(OAPageContext pageContext, OAWebBean webBean)
super.processRequest(pageContext, webBean);
OAApplicationModule am = pageContext.getApplicationModule(webBean);
OAViewObject pvo = (OAViewObject)am.findViewObject("pprPVO1");
pvo.setMaxFetchSize(0);
Row newRow = pvo.createRow();
pvo.insertRow(newRow);
OAViewObject vo = (OAViewObject)am.findViewObject("Headers_VO1");
String status="";
status=vo.getCurrentRow().getAttribute("Status").toString();
if(status!=null && !("".equalsIgnoreCase(status)))
if(status.equalsIgnoreCase("IN PROCESS"))
pvo.getCurrentRow().setAttribute("hdr1Trans",Boolean.TRUE);
else if(status.equalsIgnoreCase("NEW"))
pvo.getCurrentRow().setAttribute("hdr1Trans",Boolean.FALSE);
Code in my processFormRequest method is as follows:_
public void processFormRequest(OAPageContext pageContext, OAWebBean webBean)
super.processFormRequest(pageContext, webBean);
OAApplicationModule am = pageContext.getApplicationModule(webBean);
String headerId ="";
System.out.println("test-1");
String item1=pageContext.getParameter("item1").toString();
String item2=pageContext.getParameter("item2").toString();
I am getting the NPE error when I am trying to access a record with status value IN PROCESS.
Once I make the read only property to TRUE for both the above 2 items and after that if iam trying to access their value using pageContext.getParameter Iam getting this error.
Kindly please help me in resolving this error.
Many thanks in advance.

Arun,
When you set item as readonly field, it will always show null when you will use pageContext.getParameter("<itemID>").
If there is a VO attached with these items eg- item1, item2 then you can get the value using below code
OAViewObject vo = (OAViewObject)am.findViewObject("<Some Vo>");
String item1=(String) vo.getCurrentRow().getAttribute("<Attribute Name>");Regards,
