I just found an example of a hardcoded array that does what I want:
private var masterData:Array = [
{ OrderId: 10248, CustomerId:"WILMK", EmployeeId:5,
OrderDate:"1-Feb-2007",
children:[
[
{ProductId:11, ProductName:"Quesbo
Cabrales", UnitPrice:14, Quantity:12, Discount:0, Price:168},
{ProductId:42, ProductName:"Singaporean
Hokkien Fried Mee", UnitPrice:9.8, Quantity:10, Discount:0, Price:98},
{ProductId:42, ProductName:"Mozzarella
di Giovanni", UnitPrice:34.8, Quantity:5, Discount:0, Price:174}
]
]}
]
]}
this is form this blog:

When I debug my collection (recalls is the arraycollection i use) as it is
returned from the server I am seeing something like this:
recalls[0] - RecallRecord object
- prop
- prop
- groupedTrades - ArrayCollection that I want to use as DP for renderProvider
groupedTrades[0] - Generic Object
groupedTrades[1] - Generic object
I fail to see the difference between the hardcoded version from the blog that
works and the data I'm using from my service. What am I missing?
thank you!
