Oracle ADF :Copy eo

Question

hello! all!
i want to ask sth about Copy EO..
i have master-detail relationship..
i want to copy all table before commit transaction.
but i can copy master table,can not copy detail table
i think the problem is i can't get detail table in master table's doDML method.
this is my code
* Custom DML update/insert/delete logic here.
* @param operation the operation type
* @param e the transaction event
protected void doDML(int operation, TransactionEvent e) {
if (operation == DML_INSERT) {
this.setPlanId(this.getSeqBySeqName(PlanAppModuleConst.PRLEOPUSPLANSSEQ));
}else if (operation == DML_UPDATE) {
//change operation to insert
operation=DML_INSERT;
Integer planId=this.getSeqBySeqName(PlanAppModuleConst.PRLEOPUSPLANSSEQ);
Integer versionNo=this.getVersionNo()+1;
//copy all attrName
for(String attrName:this.getAttributeNames()){
if(!attrName.endsWith("EO")&&!"PrlEopusPlanProviders".equals(attrName)){
this.setAttributeByName(attrName);
//detail table
else{
//here is the problem....i get the eo here not vo.is it a problem?
RowIterator rowIter = (RowIterator)this.getAttributeInternal(attrName);
if(Beans.isNotEmpty(rowIter.getAllRowsInRange())){
for(Row _row:rowIter.getAllRowsInRange()){
for(String rowAttrName:_row.getAttributeNames()){
if("PlanId".equals(rowAttrName)){
this.setRowAttributeByName(_row,rowAttrName,planId);
}else if("PlanVersionNo".equals(rowAttrName)){
this.setRowAttributeByName(_row,rowAttrName,versionNo);
}else if("PlanType".equals(rowAttrName)){
this.setRowAttributeByName(_row,rowAttrName,this.getPlanType());
}else if("CalMethod".equals(rowAttrName)){
this.setRowAttributeByName(_row,rowAttrName,this.getCalMethod());
else if ("RateId".equals(rowAttrName)) {
this.setRowAttributeByName(_row,rowAttrName,
this.getSeqBySeqName(PlanAppModuleConst.PRLEOPUSPLANBENRATESEQ));
} else if ("ProviderId".equals(rowAttrName)) {
this.setRowAttributeByName(_row,rowAttrName, this.getSeqBySeqName(PlanAppModuleConst.PRLEOPUSPLANPROVIDERSSEQ));
else{
this.setRowAttributeByName(_row,rowAttrName);
// this.setAttribute(attrName, rowIter);
this.setPlanId(planId);
this.setVersionNo(versionNo);
super.doDML(operation, e);

hi Ravi Nuka
here is my code
* Custom DML update/insert/delete logic here.
* @param operation the operation type
* @param e the transaction event
protected void doDML(int operation, TransactionEvent e) {
if (operation == DML_INSERT) {
this.setPlanId(this.getSeqBySeqName(PlanAppModuleConst.PRLEOPUSPLANSSEQ));
}else if (operation == DML_UPDATE) {
//change operation to insert
operation=DML_INSERT;
Integer planId=this.getSeqBySeqName(PlanAppModuleConst.PRLEOPUSPLANSSEQ);
Integer versionNo=this.getVersionNo()+1;
//copy all attrName
for(String attrName:this.getAttributeNames()){
if(!attrName.endsWith("EO")&&!"PrlEopusPlanProviders".equals(attrName)){
this.setAttributeByName(attrName);
//detail table
else{
//here is the problem....i get the eo here not vo.is it a problem?
RowIterator rowIter = (RowIterator)this.getAttributeInternal(attrName);
if(Beans.isNotEmpty(rowIter.getAllRowsInRange())){
for(Row _row:rowIter.getAllRowsInRange()){
for(String rowAttrName:_row.getAttributeNames()){
if("PlanId".equals(rowAttrName)){
this.setRowAttributeByName(_row,rowAttrName,planId);
}else if("PlanVersionNo".equals(rowAttrName)){
this.setRowAttributeByName(_row,rowAttrName,versionNo);
}else if("PlanType".equals(rowAttrName)){
this.setRowAttributeByName(_row,rowAttrName,this.getPlanType());
}else if("CalMethod".equals(rowAttrName)){
this.setRowAttributeByName(_row,rowAttrName,this.getCalMethod());
else if ("RateId".equals(rowAttrName)) {
this.setRowAttributeByName(_row,rowAttrName,
this.getSeqBySeqName(PlanAppModuleConst.PRLEOPUSPLANBENRATESEQ));
} else if ("ProviderId".equals(rowAttrName)) {
this.setRowAttributeByName(_row,rowAttrName, this.getSeqBySeqName(PlanAppModuleConst.PRLEOPUSPLANPROVIDERSSEQ));
else{
this.setRowAttributeByName(_row,rowAttrName);
// this.setAttribute(attrName, rowIter);
this.setPlanId(planId);
this.setVersionNo(versionNo);
super.doDML(operation, e);
