JBO-26048 error after insert delete commit

Question

Using JDeveloper 10.1.2 running local OC4J against Oracle 9i database
* JBO-26048: Constraint "APPLREFLTR_PK" violated during post operation:"Insert" using SQL Statement "BEGIN INSERT INTO DCSAT_APPL_REF_LETTER(APPLICANT_ID,LETTER_ID,LETTER_INF,CREATED_BY,CREATED_DATE,UPDATED_BY,UPDATED_DATE) VALUES (:1,:2,:3,:4,:5,:6,:7) RETURNING APPLICANT_ID INTO :8; END;".
* ORA-00001: unique constraint (APPTRACK.APPLREFLTR_PK) violated ORA-06512: at line 1
This was working yesterday??? I was so close then spent a day trying to track down what broke. I tried changing the database primary key to deferrable, which just changed the error message to one that said I had too many primary keys.
Basically the following code inserts a blank row into the view object. It then looks for an existing record, if found row.remove() is called on the found row. I then update the primary key in the current record from data on the form. (The primary key is set as a dbsequence, but there isn't a trigger to set it.) then commit. I was thinking that it was the chronological order bit that is listed in the latest ADF documentation. The thing is, this did work. A case of turning off the computer, removing all class files, rebuilding the tables and running the app - now broken...
I would appreciate ideas on where to troubleshoot, or help on how to troubleshoot this one.
Thanks,
Ken
I am uploading files into an ORDSYS.ORDDOC datatype following example 3 from Steve Muench's weblog. Here is the code in my DataActionForward:
<code>
public class UploadReferenceLettersAction extends DataForwardAction {
protected void processUpdateModel(DataActionContext actionContext) {
System.out.println("*** UploadReferenceLettersAction.processUpdateModel() ***");
super.processUpdateModel(actionContext);
if (!(handlingEvents(actionContext))) {
/* Create a blank record in the model and set it as the current row - only the first time in. */
BindingContext bc = actionContext.getBindingContext();
DCDataControl dc = bc.findDataControl("ApptrackModuleDataControl");
ApptrackModule service = (ApptrackModule)dc.getDataProvider();
service.insertRowRefLetterView();
protected void findForward(DataActionContext actionContext) throws Exception {
System.out.println("*** UploadReferenceLettersAction.findForward() ***");
/* Try to catch errors instead of the default error handler. */
try {
List events = actionContext.getEvents();
if (events != null && events.size() > 0) {
ListIterator li = events.listIterator();
while (li.hasNext()) {
System.out.println("UploadApplicantResumeAction.findForward()- event : " + li.next().toString());
} catch (Exception e) {
System.out.println(e.getMessage() );
// e.printStackTrace(System.out);
super.findForward(actionContext);
public void onCommit( DataActionContext ctx ) {
System.out.println("*** UploadReferenceLettersAction.onCommit() ***");
/* Get LetterId from the form
DCBindingContainer bindings = ctx.getBindingContainer();
DCControlBinding binding;
binding = bindings.findCtrlBinding("LetterId");
String letterId = (binding != null) ? binding.toString() : "";
DBSequence letterID = new DBSequence(letterId);
/* get applicantId */
HttpSession session = ctx.getHttpServletRequest().getSession();
String applicantId = "" + (String)session.getAttribute("applicantid");
DBSequence applicantID = new DBSequence(applicantId);
/* Remove and existing record with applicantId and letterId */
BindingContext bctx = ctx.getBindingContext();
DCDataControl dc = bctx.findDataControl("ApptrackModuleDataControl");
ApptrackModule service = (ApptrackModule)dc.getDataProvider();
// service.deleteRefLetterByApplicantidLetterid(applicantId, letterId); // passing values as Strings
service.deleteRefLetterByApplicantidLetterid(applicantId); // passing values as Strings
/* Update the currentRow */
System.out.println("UploadReferenceLettersAction.onCommit() - applicantId = " + applicantId);
// System.out.println("UploadReferenceLettersAction.onCommit() - letterId = " + letterId);
DCBindingContainer bc = ctx.getBindingContainer();
DCIteratorBinding iter = bc.findIteratorBinding("ApplRefLetterView1Iterator");
Row r = iter.getCurrentRow();
r.setAttribute("ApplicantId",applicantID); // Setting value that is of type DBSequence
// r.setAttribute("LetterId",letterID); // Setting value that is of type DBSequence
/* Commit the transaction */
System.out.println("UploadReferenceLettersAction.onCommit() - Saving upload starting");
if (ctx.getEventActionBinding() != null) {
ctx.getEventActionBinding().doIt();
System.out.println("UploadReferenceLettersAction.onCommit() - Saving upload complete");
ctx.setActionForward(ctx.getActionMapping().findForward("success"));
public void onRollback(DataActionContext ctx) {
System.out.println("*** UploadReferenceLettersAction.onRollback() ***");
ctx.setActionForward(ctx.getActionMapping().findForward("Edit"));
if (ctx.getEventActionBinding() != null) {
ctx.getEventActionBinding().doIt();
protected boolean handlingEvents(DataActionContext ctx) {
List events = ctx.getEvents();
return (events != null) && (events.size() > 0);

In my ApplicationModule, I have the following methods for adding and deleting code:
<code>
public void insertRowRefLetterView() {
ViewObject vo = getApplRefLetterView1();
Row aRow = vo.createRow();
vo.insertRow(aRow);
vo.setCurrentRow(aRow);
public void deleteRefLetterByApplicantidLetterid(String applicantId) {
Key k = new Key(new Object[] { new DBSequence(applicantId) });
System.out.println("ApptrackModuleImpl.deleteRefLetterByApplicantidLetterid(applicantId) - key = " + k.toStringFormat(false));
ViewObject vo = getApplRefLetterView1();
Row[] r = vo.findByKey(k, 1);
if (r.length < 1) {
System.out.println("ApptrackModuleImpl.deleteRefLetterByApplicantidLetterid(applicantId) - No key to delete");
} else {
System.out.println("ApptrackModuleImpl.deleteRefLetterByApplicantidLetterid(applicantId) - Found key to delete");
Row rowFound = r[0];
String appId = rowFound.getAttribute("ApplicantId").toString();
System.out.println("ApptrackModuleImpl.deleteRefLetterByApplicantidLetterid(applicantId) - appId = " + appId);
rowFound.remove();
return;
</code>

I ran again with the -Djbo.debugoutput=console
There was one line that didn't seem right:
EntityCache:add WARNING - new row key matches a removed row
Shortly after this, I get the primary key violation.
*** UploadReferenceLettersAction.onCommit() ***
ApptrackModuleImpl.deleteRefLetterByApplicantidLetterid(applicantId) - key = 00010000000132
ApptrackModuleImpl.deleteRefLetterByApplicantidLetterid(applicantId) - Found key to delete
ApptrackModuleImpl.deleteRefLetterByApplicantidLetterid(applicantId) - appId = 2
