Thanks Ben.
I may be trying the wrong thing here, but this is the only working way I came up with:
<mx:XMLListCollection id="xlcReportGrid" source="{XMLList(cbReportInfoName.selectedItem.lineItems.columns.column)}"/>
and then the Text control that binds to it:
<mx:Text htmlText="{xlcReportGrid.getItemAt(0).content}" />
cbReportInfoName is a dropdown combo (the last in a chain) that gets its data from another combo which gets its data from an HTTPService (e4x). It seems, whenever the data gets "thru" the dataprovider of a ComboBox, its selectedItem object is not a XMLListCollection anymore (I think this was different with an ArrayCollection - before I used e4x as resultFormat from the HTTPService).
The problem with the above is that I cannot use the following (I would like to bind to nodes on different levels):
<mx:XMLListCollection id="xlcReportGrid" source="{XMLList(cbReportInfoName.selectedItem)}"/>
and then bind it like this:
<mx:Text htmlText="{xlcReportGrid.lineItems.columns.column.getItemAt(0).content}" />
This throws a compile error of "access to a possibly undefined property 'lineitems'..." Any ideas? thx -Iko
