RE: [flexcoders] Re: Multiple XML loads?

[Tracy Spratt]

This is what I would do: Set the resultFormat=”e4x” Create an instance variable for the main dataProvider: private var _xmlDpMain:XML; Have the result event call a result handler function, and in that do: _xmlDpMain = event.result; //set the global var value trace(_xmlDpMain.toXMLString()); //to be sure I have what I expect   bind the main combobox to _xmlDPMain.Prov (whatever works for the main combo).   In a click/change event on the main combobox call a function and do this: Var xmlDpDetail:XML = XML(comboMain.selectedItem);    //the XML function might not be required, I still get tripped ub by data type issues. Assign that var to the detail combobox dataProvider: comboDetail.dataProvider = xmlDpDetail;   Let us know.   Tracy From: flexcoders@yahoogroups.com [mailto:[EMAIL PROTECTED] On Behalf Of Jamie O Sent: Friday, September 15, 2006 12:35 PM To: flexcoders@yahoogroups.com Subject: [flexcoders] Re: Multiple XML loads?   God @(#$& do I not so much enjoy being at the bottom of a learning curve. I can't fathom why putting the .send() into a function which is called when my button is pushed didn't occur to me but, well, it didn't. Thank you Tracy! The second piece that I am now probably doing something very stupid with is the format of the data and traversing. I haven't used XML a LOT but I understand the basics of dot notation and have the Flex 'Traversing XML Structures' document printed for reference. I have been able to populate combobox using the labelField and dataProvider when the HTTPService is default format (object). However I am trying to do a lookup in the XML based on the item a user selects from that combobox and populate a second combobox with details of children of that selected element. According to documentation if the HTTPService is set as XML or e4x the following syntax should work in the Change event: {XML_PostCode.lastResult.Prov.City.Streets.(@streetname == cmbStreet.selectedLabel).NumberRangeLow} Any attempts I did to 'stub' the HTTPService and use mx:Model or mx:XML just went very badly for me. Any help would be appreciated. --- In [EMAIL PROTECTED]ups.com, "Tracy Spratt" <[EMAIL PROTECTED]> wrote: > > I am not sure I understand "because you don't know which feed to pull at > runtime". > > > > Using AS code you can change the URL of the HTTPService call and invoke > send() at will. > > > > If you need to keep track of which result goes with which send, you can > use the ACT pattern, that allows you to set and retrieve data in an > AsyncToken. > > > > Tracy > > > > ________________________________ > > From: [EMAIL PROTECTED]ups.com [mailto:[EMAIL PROTECTED]ups.com] On > Behalf Of Jamie O > Sent: Monday, September 11, 2006 9:25 AM > To: [EMAIL PROTECTED]ups.com > Subject: [flexcoders] Multiple XML loads? > > > > Hi all, > > I have one conceptual/programming question right now I'm struggling > with.
