Yes, exactly.
Now, you do: trace(photoFeed.toXMLString()) to see exactly what you have. Depending on how you will use the photoFeed data, you could also declare an instance var to hold the actual collection of photo nodes you want to display in your list. The other was an answer to your question: "Doesnt using E4X and HTTPService essentially set up an XMLListCollection for you?" It does not, and I described what is necessary to set up an XMLListCollection. What is the context of your follow-up question? Better than what? What are you doing now?

I'm not disputing it. I just dont understand. What will this enable me to do that I'm not doing now? (Again, I'm asking to understand, not to dispute) If you just want to give me a reading list thats fine too. thanks for your time. brad -----Original Message----- From: [email protected] [mailto:[EMAIL PROTECTED] On Behalf Of Tracy Spratt Sent: Wednesday, February 06, 2008 4:42 PM To: [email protected] Subject: RE: [flexcoders] Re: Embedding String Variable in dataprovider name Yes, binding to lastResult is, as you are seeing, hard to debug. Use a result handler.

But for a more robust application, you should stop using lastResult. Direct use of lastResult is really only appropriate for prototyping. You are much better off using a result handler to process the result, handling the special cases, and putting the appropriate values into variables that you then use for the binding. --- In [email protected] <mailto:flexcoders%40yahoogroups.com> , "Brad Bueche" <[EMAIL PROTECTED]> wrote: > > This gets rid of the data binding waring but then the chart itself blows > up saying its getting null objects. > > brad > > -----Original Message----- > From: [email protected] <mailto:flexcoders%40yahoogroups.com> [mailto:[email protected] <mailto:flexcoders%40yahoogroups.com> ] On > Behalf Of jer_ela > Sent: Monday, February 04, 2008 4:01 PM > To: [email protected] <mailto:flexcoders%40yahoogroups.com> > Subject: [flexcoders] Re: Embedding String Variable in dataprovider name > > > > you can use a method to get around that > > dataProvider="{getDp(chartXML2.lastResult, month)}" > > private function getDp(lastResult:Object, month:String):String > { return lastResult[month].day; > } > > The method will be called when ever one of it parameters is changed > > --- In [EMAIL PROTECTED] <mailto:flexcoders%40yahoogroups.com> > ups.com, "Brad Bueche" <brad@> wrote: > > > > That worked! > > > > I still get the following warning: > > > > Data binding will not be able to detect changes when using square > > bracket operator.
