we're nearly there! I've created the binding document, implemented it into flow but no rows are being displayed when I update the order object!! What am I overlooking?
flow:
var form = new Form("forms/artistOrder_new.xml");
form.createBinding("binding/artistOrder_binding.xml");
form.showForm("viewform-artistOrder_new.xml",{"artistID":artistID,"artist_name":artist_name,"artist_info":artist_info,"track_info":track_info,"track_location":track_location,"track_type":track_type,"stock_code":stock_code,"userGlobal":userGlobal,"neworder":neworder,"stock_price":stock_price,"msg":delItems,"msg2":msg2, "track_title":track_title});
...........
if (parseInt(bizData.quantity) || repeaterSize != 0) {
try {
if (repeaterSize != 0) { //Delete a row if need be
//delete a row and an item from the orderitem
for(var i=0; i < repeater.getSize(); i++) { //loop over the rows
var row = repeater.getRow(i);
if(java.lang.Boolean.TRUE.equals(row.lookupWidget ("delete").value)) { //is the booleanfield checked?
itemsToDelete.add(row.lookupWidget("id").value); //add the item id to delete from widget
deleteOrderItem2(itemsToDelete);
//now delete item row from repeater
form.load(neworder);
}
}
}
if (parseInt(bizData.quantity)) { //Add a row if need be
//add a row and an item to the orderitem
addOrderItem(bizData.quantity, bizData.orderID , bizData.stockID);
//Now add this item to the repeater
form.load(neworder);
binding:

Like I mentioned before, I think the easiest way to load data into the
repeater is with a fb:simple-repeater binding. I presume you're not
familiar with the binding framework; it's basically a way to define (in
an XML syntax) how to map values between a business object and the form
object's widgets. See the documentation:
http://cocoon.apache.org/2.1/userdocs/binding.html
There's a special binding type called fb:simple-repeater (named such
since it's much simpler than the full fb:repeater binding, but should be
sufficient for your case) that lets you bind values from a Collection,
Array, or anything else that JXPath can iterate over, to and from a
fd:repeater widget and all its children. Something like:
In a binding file:
...
<fb:simple-repeater id="items" parent-path="." row-path="orderItems"
direction="load">
<fb:value id="id" path="ID" />
<fb:value id="artistName" path="..." />
...
</fb:simple-repeater>
...
In your flow:
form.createBinding("path/to/binding-file.xml"); //creates the binding
...
form.load(neworder); //loads the data into the form using the binding
That's it. You can call form.load() as many times in your flow as you
want, such as after you delete items or a new item is added. As long as
the orderItems list contains the up-to-date list of items, the repeater
will be updated to match.
