it is expected, but i just don't know how to fix it.... how do you set something selected in a component after you receive new data?
but i figured it out... thanks to a post by ben forta... the post wasn't what i wanted or needed, but there is no fun when you don't have to try.... so what you have to do is extend the List, or comboBox components.... create a new component based on the list or combo box... and in that component put the following code... <?xml version="1.0" encoding="utf-8"?> <mx:List xmlns:mx="http://www.adobe.com/2006/mxml";> <mx:Script> <![CDATA[ private var tempSelectedIndex:Number = -1; private var bDataProviderSet:Boolean = false; // Trap dataProvider being set override public function set dataProvider(o:Object):void{ tempSelectedIndex = this.selectedIndex; // invoke ComboBox version super.dataProvider = o; // This may get called before dataProvider is set, so make sure not null and has entries if (o!=null && o.length){ // Got it, set flag bDataProviderSet = true; } this.selectedIndex = tempSelectedIndex; } ]]> </mx:Script> </mx:List> i set a temporary selected index to whatever is passed, other wise it's a "-1" then after the dataprovider is set, i reset the selected index back to what it was, because the setting of the dataprovider is what empty's the value. I understand why it does it... but in coldfusion, you have select boxes... and you have <cfif> within the select box stating that if the value is equal to whatever you want to be selected then select it.... even if you tried that in this case... it would work on creationComplete, but everytime you call it there after, it would be blank... because the setting of the dataprovider erases whatever is in there... --- In [email protected], Tom Chiverton <[EMAIL PROTECTED]> wrote: > > On Tuesday 30 Jan 2007, jensen.axel wrote: > > so i'm binding to a custom class that i made, that grabs the current > > price range of the house... but whenever my dataprovider changes, the > > selected index is lost... > > I'd say this was expected. > If the user has '200-300' selected, and you update the data provider to one > that doesn't have that as an option, it wouldn't make sense to select some > random element in the new data. > > -- > Tom Chiverton > Helping to preemptively initiate visionary CEOs > > **************************************************** > > This email is sent for and on behalf of Halliwells LLP. > > Halliwells LLP is a limited liability partnership registered in England and Wales under registered number OC307980 whose registered office address is at St James's Court Brown Street Manchester M2 2JF.
