Store an Array of Classes e.g. Order / Line Items example

i posted the design since its a bit more complicated then my summarized version, but at any rate i will post the full solution for those who want to view either or...

basically this takes an XML field and creates an object Order which has some attributes plus an array of Line Item objects.

hunter9000 requested the full code, in my first post i did post a small example of pseudocode

the problem i'm having is that all the array values contain the same object

so if in the XML: Line item 1 = $500 & Line item 2 = $1500

in my array it ends up being: myarray[0].price = $500 and myarray[1].price = $500

in debugging when the setLineDetails method is called, the incoming node does contain the correct price for the 2nd iteration ($1500) - except when it executes price = my xpath query, price gets set to $500, not $1500

i've been stuck on this way too long

if you review the area that says:

// -- create line items --

this is where i am putting it into the list

i feel like it is somehow querying the old node even though i passed it a new one. the debugger however disagrees

xarfoxa at 2007-7-28 15:46:16 >

Yes, I did view the objects during debugging. I tried to explain in previous posts but maybe I was unclear.

I am testing with two line items, the first line item has a price of 500 whereas the second has a price of 1500.

During the 2nd iteration of the loop - the following happens:

Node lineItemNode = (Node) iter.next();

lineItems[i].setLineDetails(lineItemNode);

//lineItemNode.actualSalesPrice = 1500

//now it steps into my setLineDetails method

actualSalesPrice = pLineItemNode.valueOf("//ActualSalesPriceEMP/text()");

//pLineItemNode.actualSalesPrice = 1500

//actualSalesPrice gets set to 500

//weird!!
