Hi Srikant,
When user may edit the record, the same row may get updated in vo. Thus over writing existing row instead of creating new row.
Approach1..
On the page where user may edit records, instead of presenting records of existing row, present copy of existing row. So
In AM... (Later on you can put vo logic to its proper place, i.e. vo java file)
public void viewPageCallSetup()
Row originalRow=vo.createRow();
Row dummyRowForEdit=vo.createRow();
//COPY THE ORIGINAL ROW TO DUMMY ROW. IF THERE IS DIRECT METHOD TO CREATE COPY OF EXISTING ROW, THAT MAY BE MUCH BETTER.
for(int i=0;i<vo.getAttributeCount()-1; i++)
dummyRowForEdit.setAttribute(i, originalRow.getAttribute(i));
vo.insertRow(dummyRowForEdit);
vo.setNewRowState(Row.STATUS_INITIALIZED);
vo.setCurrentRow(dummyRowForEdit);
call this method in contoller's processRequest..
string oid=pagecontext.getparameter("oid");
if(pageContext.getparameter("Purpose").equals("Edit")) //Means user clickED the edit button so we need to replicate the row
am. viewPageCallSetup(oid); //calling this method in am
else
In PFR...
if(pageContext.getparameter("Purpose").equals("Edit"))
am.xxcostedit(oid); //calling this method in am
in case user selects "Cancel" on edit form,we need to remove the duplicate row. So in AM write a method to remove the duplicate rowd on click of "Cancel" button on edit form.
Rest of the logic is same for "Save" button. Just say commit.
