Problem with transient attribute attach to standard vo from the controller

Question

Hi all,
I attached two transient attributes to the standard vo through controller.
Then i passed values to these fields from controller based on another field in the standard vo.
I created two columns in the table without given the view instance and view attribute.
But in the controller i'm setting the view instance and view attribute for this two columns.
After i applied this extended controller it is working fine, but one problem is there.
Once if i clear the cache and then i enters the page, the extended fields are appearing with null. if i press F5 in the browser then its working fine.
same problem happens only when the cache cleared or server gets bounced. so i need to go each page and press F5 once then everything is fine.
Here, I shared my code, please tell me what is the problem and how to solve this.
Code:
public void processRequest(OAPageContext pageContext, OAWebBean webBean)
super.processRequest(pageContext, webBean);
OAApplicationModule am = pageContext.getApplicationModule(webBean);
OAViewObject cvo=(OAViewObject)am.findViewObject("FinalCompListVO");
if(!cvo.isPreparedForExecution()){
cvo.executeQuery();
if(cvo!=null){
try{
String temp1=cvo.findAttributeDef("XXCompNameAttr").toString();
}catch(Exception e){
cvo.addDynamicAttribute("XXCompNameAttr");
try{
String temp1=cvo.findAttributeDef("XXCompTypeAttr").toString();
}catch(Exception e){
cvo.addDynamicAttribute("XXCompTypeAttr");
Row compRow[]=cvo.getAllRowsInRange();
for(int i=0; i<compRow.length;i++){
FinalCompListVORowImpl cVORowImpl=(FinalCompListVORowImpl)compRow;
String name[]=cVORowImpl.getName().split("\\.");
String compName=name[2];
cVORowImpl.setAttribute("XXCompNameAttr",compName);
for(int i=0; i<compRow.length;i++){
FinalCompListVORowImpl cVORowImpl=(FinalCompListVORowImpl)compRow[i];
String name[]=cVORowImpl.getName().split("\\.");
String compName=name[0];
if(i==0){
cVORowImpl.setAttribute("XXCompTypeAttr","Behavioral");
}else if(i!=0&&compName.equals("FUNC")){
cVORowImpl.setAttribute("XXCompTypeAttr","Functional");
break;
OAMessageStyledTextBean mstb=(OAMessageStyledTextBean)webBean.findChildRecursive("XXCompTypeCol");
mstb.setViewUsageName("FinalCompListVO");
mstb.setViewAttributeName("XXCompTypeAttr");
OAMessageStyledTextBean mstb1=(OAMessageStyledTextBean)webBean.findChildRecursive("XXCompNameCol");
mstb1.setViewUsageName("FinalCompListVO");
mstb1.setViewAttributeName("XXCompNameAttr");
Thanks in advance,

Hi,
1. ExecuteQuery should already be executed in Base Controller, So please check if you need it. though i don't think that might be causing the issue.
cvo.executeQuery();
2. The code where you call findAttributeDef and handle the Exception, Can you debug that portion. As It may not be throwing exception in any case and so the Attributes were never added to VO and Page Displays null..
I am not sure, but i think the issue seems to be around 2.
all the best
