Extending logic behind a checkbox in iRecruitment external candidate page.

Question

Hi All,
We have a requirement to extend the logic behind the check box in Irecruitment external page (AplOtherInfoPG). The logic is buit in a AM (IrcCandidatePersonalAcountAM). Its a root AM for the page AplOtherInfoPG and its referred from many other pages too. I have extended this AM using following steps
1. FTP all the files from $JAVA_TOP/oracle/apps/per/* to your PC and configure your PC for OA Framework development
2. Create a new BC4J package in which the extension will reside.
3. Note down the path and the properties of existing AM that we wish to extend
4. Create a new AM, and specify the original AM being extended.
5. Ensure that the properties of original AM are applicable for new AM too.
6. Perform substitution. This will create a jpx file.
7. Upload the jpx file into Database.
8. Deploy the custom BC4J to $JAVA_TOP by FTP'ing all files.
9. Bounce the server
After this change I'm getting the error 'JBO-29000: Unexpected exception caught: java.lang.StackOverflowError, msg=null'. This error is appearing on all the pages where the same AM(IrcCandidatePersonalAcountAM) is referred. Its totally clueless.
I have got an suggestion that extending an root AM is not recommanded in OAF. If So, how I should go about it.
Please help me to achieve this requirement.
Thanks,
Guru

Hi Guru,
As you mentioned extending the rootAM is not advisable.
As a workaround what you can try is
1) Extend the controller in your page,
and get the RootAM, ChildAM, Your VO(where you have the checkbox attribute is there) and then set the value what do you wanted.
Use the below code to get your required AM and VO, please change the sample code according to your AM name...etc.
// Get requested AM from Root am
public OAApplicationModule getRequestedAM(OAPageContext pageContext, String requestedAMName)
writeLog(pageContext,"Requested AM called to check the AM "+requestedAMName );
String amName = "";
String objectivesAMName = requestedAMName;//"ObjectivesAM";
String nestedAMArray[] = pageContext.getRootApplicationModule().getApplicationModuleNames();
pageContext.writeDiagnostics(this,"Root AM=>"+pageContext.getRootApplicationModule().getName() + " Child AMs=>"+ nestedAMArray.length,1);
OAApplicationModule currentAM = null;
currentAM = (OAApplicationModule)pageContext.getRootApplicationModule();
for(int i = 0; i < nestedAMArray.length; i++)
amName = nestedAMArray;
pageContext.writeDiagnostics(this,"Nested AM Name=>"+amName + "and amName.indexOf(objectivesAMName) "+amName.indexOf(objectivesAMName),1);
currentAM = (OAApplicationModule)pageContext.getRootApplicationModule().findApplicationModule(amName);
                    //Get the view names
               String[] viewNames = currentAM.getViewObjectNames();
for (int i =0 ;i<viewNames.length ;i++ )
writeLog(pageContext,i +" Value "+viewNames[i]);
if(!(amName.indexOf(objectivesAMName)==-1))
pageContext.writeDiagnostics(this,"Found Handle to My Nested AM " + amName ,1);
break;
return currentAM;
Get the VO from the AM
OAViewObject objAssessmentVO = (OAViewObject)yourAM.findViewObject("yourVO");
Get all the attribute from a VO with Attribute Names in Custom CO
OAApplicationModule rootAM = pageContext.getRootApplicationModule();
OAApplicationModule apprAM = (OAApplicationModule)rootAM.findApplicationModule("AppraisalsAM");
String offlineStatus = (String)apprAM.invokeMethod("getOfflineStatus",new Serializable[]{appraisalId+""});
OAViewObject appraisalVO = (OAViewObject)apprAM.findViewObject("AppraisalVO");
if(appraisalVO !=null)
AppraisalVORowImpl appraisalVORow = (AppraisalVORowImpl) appraisalVO.first();
if(appraisalVORow !=null)
int attrCount = appraisalVO.getAttributeCount();
writeLog("XXRBG",pageContext,"Attrbuute count "+attrCount);
String[] attributeNames = appraisalVORow.getAttributeNames();
for (int i = 0 ;i< attributeNames.length ;i++ )
writeLog("XXRBG",pageContext," Name "+attributeNames[i] +" = "+appraisalVORow.getAttribute(i));
