Getting error Unable to perform transaction on the record.

Question

Hi,
My requirement is to implement the custom attachment, and to store the data into custom lob table.
my custom table structure is similer to that of standard fnd_lobs table and have inserted the data through EO based VO.
Structure of custom table
CREATE TABLE XXAPL.XXAPL_LOBS
ATTACHMENT_ID NUMBER NOT NULL,
FILE_NAME VARCHAR2(256 BYTE),
FILE_CONTENT_TYPE VARCHAR2(256 BYTE) NOT NULL,
FILE_DATA BLOB,
UPLOAD_DATE DATE,
EXPIRATION_DATE DATE,
PROGRAM_NAME VARCHAR2(32 BYTE),
PROGRAM_TAG VARCHAR2(32 BYTE),
LANGUAGE VARCHAR2(4 BYTE) DEFAULT ( userenv ( 'LANG') ),
ORACLE_CHARSET VARCHAR2(30 BYTE) DEFAULT ( substr ( userenv ( 'LANGUAGE') , instr ( userenv ( 'LANGUAGE') , '.') +1 ) ),
FILE_FORMAT VARCHAR2(10 BYTE) NOT NULL
i have created a simple messegefileupload and submit button on my custom page and written below code on CO:
Process Request Code:
if(!pageContext.isBackNavigationFired(false))
TransactionUnitHelper.startTransactionUnit(pageContext, "AttachmentCreateTxn");
if(!pageContext.isFormSubmission()){
System.out.println("In ProcessRequest of AplAttachmentCO");
am.invokeMethod("initAplAttachment");
else
if(!TransactionUnitHelper.isTransactionUnitInProgress(pageContext, "AttachmentCreateTxn", true))
OADialogPage dialogPage = new OADialogPage(NAVIGATION_ERROR);
pageContext.redirectToDialogPage(dialogPage);
ProcessFormRequest Code:
if (pageContext.getParameter("Upload") != null)
DataObject fileUploadData = (DataObject)pageContext.getNamedDataObject("FileItem");
String strFileName = null;
strFileName = pageContext.getParameter("FileItem");
if(strFileName == null || "".equals(strFileName))
throw new OAException("Please select a File for upload");
fileName = strFileName;
contentType = (String)fileUploadData.selectValue(null, "UPLOAD_FILE_MIME_TYPE");
BlobDomain uploadedByteStream = (BlobDomain)fileUploadData.selectValue(null, fileName);
String strItemDescr = pageContext.getParameter("ItemDesc");
OAFormValueBean bean = (OAFormValueBean)webBean.findIndexedChildRecursive("AttachmentId");
String strAttachId = (String)bean.getValue(pageContext);
System.out.println("Attachment Id:" +strAttachId);
int aInt = Integer.parseInt(strAttachId);
Number numAttachId = new Number(aInt);
Serializable[] methodParams = {fileName, contentType , uploadedByteStream , strItemDescr , numAttachId};
Class[] methodParamTypes = {fileName.getClass(), contentType.getClass() , uploadedByteStream.getClass() , strItemDescr.getClass() , numAttachId.getClass()};
am.invokeMethod("setUploadFileRowData", methodParams, methodParamTypes);
am.invokeMethod("apply");
System.out.println("Records committed in lobs table");
if (pageContext.getParameter("AddAnother") != null)
pageContext.forwardImmediatelyToCurrentPage(null,
true, // retain AM
OAWebBeanConstants.ADD_BREAD_CRUMB_YES);
if (pageContext.getParameter("cancel") != null)
am.invokeMethod("rollbackShipment");
TransactionUnitHelper.endTransactionUnit(pageContext, "AttachmentCreateTxn");
Code in AM:
public void apply(){
getTransaction().commit();
public void initAplAttachment() {
OAViewObject lobsvo = (OAViewObject)getAplLobsAttachVO1();
if (!lobsvo.isPreparedForExecution())
lobsvo.executeQuery();
Row row = lobsvo.createRow();
lobsvo.insertRow(row);
row.setNewRowState(Row.STATUS_INITIALIZED);
public void setUploadFileRowData(String fName, String fContentType, BlobDomain fileData , String fItemDescr , Number fAttachId)
AplLobsAttachVOImpl VOImpl = (AplLobsAttachVOImpl)getAplLobsAttachVO1();
System.out.println("In setUploadFileRowData method");
System.out.println("In setUploadFileRowData method fAttachId: "+fAttachId);
System.out.println("In setUploadFileRowData method fName: "+fName);
System.out.println("In setUploadFileRowData method fContentType: "+fContentType);
RowSetIterator rowIter = VOImpl.createRowSetIterator("rowIter");
while (rowIter.hasNext())
AplLobsAttachVORowImpl viewRow = (AplLobsAttachVORowImpl)rowIter.next();
viewRow.setFileContentType(fContentType);
viewRow.setFileData(fileData);
viewRow.setFileFormat("IGNORE");
viewRow.setFileName(fName);
rowIter.closeRowSetIterator();
System.out.println("setting on fndlobs done");
The attchemnt id is the sequence generated number, and its defaulting logic is written in EO
public void create(AttributeList attributeList) {
super.create(attributeList);
OADBTransaction transaction = getOADBTransaction();
Number attachmentId = transaction.getSequenceValue("xxapl_po_ship_attch_s");
setAttachmentId(attachmentId);
public void setAttachmentId(Number value) {
System.out.println("In ShipmentsEOImpl value::"+value);
if (getAttachmentId() != null)
System.out.println("In AplLobsAttachEOImpl AttachmentId::"+(Number)getAttachmentId());
throw new OAAttrValException(OAException.TYP_ENTITY_OBJECT,
getEntityDef().getFullName(), // EO name
getPrimaryKey(), // EO PK
"AttachmentId", // Attribute Name
value, // Attribute value
"AK", // Message product short name
"FWK_TBX_T_EMP_ID_NO_UPDATE"); // Message name
if (value != null)
// Attachment ID must be unique. To verify this, you must check both the
// entity cache and the database. In this case, it's appropriate
// to use findByPrimaryKey() because you're unlikely to get a match, and
// and are therefore unlikely to pull a bunch of large objects into memory.
// Note that findByPrimaryKey() is guaranteed to check all AplLobsAttachment.
// First it checks the entity cache, then it checks the database.
OADBTransaction transaction = getOADBTransaction();
Object[] attachmentKey = {value};
EntityDefImpl attachDefinition = AplLobsAttachEOImpl.getDefinitionObject();
AplLobsAttachEOImpl attachment =
(AplLobsAttachEOImpl)attachDefinition.findByPrimaryKey(transaction, new Key(attachmentKey));
if (attachment != null)
throw new OAAttrValException(OAException.TYP_ENTITY_OBJECT,
getEntityDef().getFullName(), // EO name
getPrimaryKey(), // EO PK
"AttachmentId", // Attribute Name
value, // Attribute value
"AK", // Message product short name
"FWK_TBX_T_EMP_ID_UNIQUE"); // Message name
setAttributeInternal(ATTACHMENTID, value);
Issue faced:
When i run the page for the first time data gets inserted into custom table perfectly on clicking upload button,
but when clicked on add another button on the same page (which basically redirects to the same upload page and increments the attachment id by 1)
i am getting the below error:
Error
Unable to perform transaction on the record.
Cause: The record contains stale data. The record has been modified by another user.
Action: Cancel the transaction and re-query the record to get the new data.
Have spent entire day to resolve this issue but no luck.
Any help on this will be appreciated, let me know if i am going wrong anywhere.
Thanks nd Regards

Hi,
After, inserting the values please re-execute the VO query.
Also, try to redirect the page with no AM retension
