I have a Rails App that produces XML data in the structure:
<price_sets>
<price_set>
<id>56</id>
<start_date>2006-11-25</start_date>
<status>O</status>
<store_set>
<id>528</id>
<name>Small size Stores</name>
</store_set>
</price_set>
..
</price_sets>
The data is returned via a HTTPService:
<mx:HTTPService id="priceSetSummary" useProxy="false" method="GET"
url="http://localhost:3000/price_set/list";>
<mx:request xmlns="">
<vendor_id>{vendorIdToUse}</vendor_id>
</mx:request>
</mx:HTTPService>
I populate a DataGrid with this data:
dataProvider="{priceSetSummary.lastResult.price_sets.price_set}"
I have 2 columns in the grid:
<mx:DataGridColumn headerText="Start Date" dataField="start_date"/>
<mx:DataGridColumn headerText="Status" dataField="status"/>
But the problem is when I want to add a column for the store set name
<mx:DataGridColumn headerText="Stores" dataField="store_set.name"/>
No values are displayed in this column.
Using the FlexBuilder debugger, I can see that there is a value
for the store set name.
I noticed that the dataProvider for the grid is an array collection,
could this be the problem. Do I need to have the data in Flex as an
XMLList or XMLListCollection. How do you get the HTTPService result
into XML for the grid.
I admit I have tried different ways with XMLList etc, but do not get
any data in the grid.
Thanks
Andrew
