IExpense - Could not get handle to the Attachments VO

Question

Friends, I am stuck, so thought to get your help.
On iExpense Final Review Page "FinalReviewPG" Submitt button, We have a requirement to throw the exception to user if he/she does not attach the Receipts Attachments with some specific Attachment Categories. In order to acheive this I need to get Handle to the Attachments VO but I could not as It throws the Java Exception error upon getting handle to the Attachments VO even though i added few atatchments and they showup on screen. Below is the portion of the problematic code and after that the full code. Thanks for your help.
//below is the problmeatic code
OAApplicationModule RootAM = oapagecontext.getRootApplicationModule();
//OAApplicationModule AttachAM = (OAApplicationModule)RootAM.findApplicationModule("OAAttachmentsAM");//doesnt work
//OAApplicationModule AttachAM = (OAApplicationModule)RootAM.findApplicationModule("oracle_apps_fnd_server_OAAttachmentsAM");//get the AM handle but null VOs
OAAttachmentsAMImpl AttachAM = (OAAttachmentsAMImpl)RootAM.findApplicationModule("oracle_apps_fnd_server_OAAttachmentsAM");//throws me java null pointer exception
FndAttachedDocumentsDomExtensionVORowImpl AttachRow =
(FndAttachedDocumentsDomExtensionVORowImpl)AttachAM.getFndAttachedDocumentsDomExtensionVO().getCurrentRow();
String strCategory = AttachRow.getAttachmentCategoryName();
oapagecontext.writeDiagnostics("tc.oracle.apps.ap.oie.webui.TCFinalReviewPageCO",
"IM90978: 14-Feb-2013 14:32 strCategory = "+ strCategory, 2);

Hi,
Check and see the below code works or not, see which option suits for you,
1) Check any attachment is there or not
======================================
public boolean checkAttachment(OAPageContext oapagecontext,OAWebBean oawebbean)
OAApplicationModule am = oapagecontext.getApplicationModule(oawebbean);
String amName = "";
String objectivesAMName = "OAAttachmentsAM";
String objectiveVOName = "FndAttachedDocumentsDomExtensionVO";
String nestedAMArray[] = am.getApplicationModuleNames();
oapagecontext.writeDiagnostics(this,"Root AM=>"+am.getName() + " Child AMs=>"+ nestedAMArray.length,1);
OAApplicationModule currentAM = null;
OAViewObject vo = null;
boolean isAttachmentFound = false;
currentAM = am;
for(int i = 0; i < nestedAMArray.length; i++)
amName = nestedAMArray;
oapagecontext.writeDiagnostics(this,"Nested AM Name=>"+amName + "and amName.indexOf(objectivesAMName) "+amName.indexOf(objectivesAMName),1);
currentAM = (OAApplicationModule)am.findApplicationModule(amName);
//Get the view names
oapagecontext.writeDiagnostics(this,"Nested AM Value "+currentAM.getName(),1);
if(!(amName.indexOf(objectivesAMName)==-1))
String[] viewNames = currentAM.getViewObjectNames();
for (int j =0 ;j<viewNames.length ;j++ )
if(viewNames[j].indexOf(objectiveVOName) > 0){
vo = (OAViewObject)currentAM.findViewObject(viewNames[j]);
if(vo!=null && vo.getFetchedRowCount() > 0){
oapagecontext.writeDiagnostics(this,"View object name "+viewNames[j]+" Row Count"+vo.getFetchedRowCount(),1);
isAttachmentFound = true;
break;
oapagecontext.writeDiagnostics(this,"Found Handle to My Nested AM " + amName ,1);
return isAttachmentFound;
2) Check the attachment count when the auto commit is false:
public boolean checkAttachment(OAPageContext oapagecontext,OAWebBean oawebbean){
OAApplicationModule am = oapagecontext.getApplicationModule(oawebbean);
String amName = "";
String objectivesAMName = "OAAttachmentsAM";
String objectiveVOName = "FndAttachedDocumentsDomExtensionVO";
String nestedAMArray[] = am.getApplicationModuleNames();
oapagecontext.writeDiagnostics(this,"Root AM=>"+am.getName() + " Child AMs=>"+ nestedAMArray.length,1);
OAApplicationModule currentAM = null;
OAViewObject vo = null;
boolean isAttachmentFound = false;
currentAM = am;
for(int i = 0; i < nestedAMArray.length; i++)
amName = nestedAMArray[i];
oapagecontext.writeDiagnostics(this,"Nested AM Name=>"+amName + "and amName.indexOf(objectivesAMName) "+amName.indexOf(objectivesAMName),1);
currentAM = (OAApplicationModule)am.findApplicationModule(amName);
//Get the view names
oapagecontext.writeDiagnostics(this,"Nested AM Value "+currentAM.getName(),1);
if(!(amName.indexOf(objectivesAMName)==-1))
String[] viewNames = currentAM.getViewObjectNames();
for (int j =0 ;j<viewNames.length ;j++ )
if(viewNames[j].indexOf(objectiveVOName) > 0){
vo = (OAViewObject)currentAM.findViewObject(viewNames[j]);
if(vo!=null && vo.getFetchedRowCount() > 0){
oapagecontext.writeDiagnostics(this,"View object name "+viewNames[j]+" Row ount"+vo.getFetchedRowCount(),1);
isAttachmentFound = true;
break;
oapagecontext.writeDiagnostics(this,"Found Handle to My Nested AM " + amName ,1);
return isAttachmentFound;
With regards,
Kali.
