New inserted detail row is not showing through accessor

Question

I have to insert master and detail row. I insert row in master view  and then I get detail row using getAttribute on master view. Then I insert row into detail row. Result is one inserted master row and no data display in detail view.
How ever in managed bean when I get master view using finditerator and then get detail row also using finditerator on the specific page then rows inserted on master and detail view appear.
DCIteratorBinding dcIter =             ADFUtils.findIterator("PlotMst1Iterator");
ViewObject mvo = dcIter.getViewObject();
mvo.insertRowAtRangeIndex(0, row);
mvo.setCurrentRow(row);
Row row = mvo.createRow();
// DETAIL ACCESSOR  not working
  //  RowSet Pd = (RowSet) row.getAttribute("PlotDtl");
DCIteratorBinding dcIter2 =       ADFUtils.findIterator("PlotDtl2Iterator");      
ViewObject dvo = dcIter2.getViewObject();
nvp.setAttribute("FabricCode",r.getAttribute("FabricCode"));
Row drow = dvo.createAndInitRow(nvp);      
dvo.insertRow(drow);

Hi,
its a classical programming mistake you do. You create a new row on the model layer and not the binding layer. The proper way of doing this would be to
1) either create a method binding for the "CreateInsert" operation in the PageDef file and call it from there
or
2) DCIteratorBinding dcIter = ADFUtils.findIterator("PlotMst1Iterator");
    Row rw = dcIter.getRowSetIterator().createRow();
Same for your attempt to create the detail row. Again you can expose the createInsert operation in the PageDef file or use the RowSetIterator. As you create a master and detail row at the same time, be aware of a constraint problem that may arise from this as you have no guarantee that the master is inserted first. Read this http://docs.oracle.com/cd/E35521_01/web.111230/e16182/bcentities.htm#CEGJAFCF to learn about the problem.
Note that use case often matters. While I can see where your coding goes wrong, I can't tell if your approach in general could be chosen better
