Java Development Tools

Hi

I have an ADF BC application written in jdev 10.1.3.3

In the application is an order page where the user views the items in their basket and enters quantities to order. If any of the quantities exceeds stock I want to prevent the order being placed.

The page has an items table and its child - an options table. The items and options VOs are linked via a view link. I want to loop through each row of the items table and check that none of the quantities entered for the related options exceed stock.

I am doing this in a backing bean using the following code which seems to work

    FacesContext fc = FacesContext.getCurrentInstance();
    Application app = fc.getApplication();
    ValueBinding bind = app.createValueBinding("#{bindings}");
    DCBindingContainer bindings2 = (DCBindingContainer)bind.getValue(fc);
    DCIteratorBinding iter = bindings2.findIteratorBinding("WsOrderItemsView1Iterator");
    RowSetIterator rsi = iter.getRowSetIterator();
    
    for (Row row = rsi.first(); row != null; row = rsi.next())
    {
       System.out.println("@tot val <"+row.getAttribute("TotalValue")+">");
        System.out.println("@col size <"+row.getAttribute("WsColourSizeView")+">");
        
         DCIteratorBinding iter2 = bindings2.findIteratorBinding("WsColourSizeView1Iterator");
         RowSetIterator rsi2 = iter2.getRowSetIterator();
         for (Row row2 = rsi2.first(); row2 != null; row2 = rsi2.next())
         {
           System.out.println("sty <"+row2.getAttribute("StyName")+">");
         }

However I noticed that WsColourSizeView (the options VO) was listed as an attribute of the WsOrderItemsView1Iterator (items VO). I wondered if it is possible to use that attribute to point to the rows of the options VO related to the current row of the items VO? It would be more elegant than grabbing another iterator from the bindings.

thanks
