Unless you have something that is preventing you from actually binding
in mxml, you should just add dataProvider="{mycomponent.MyDataList}" as
a property in the mx:List component. If you want to setup the bind in
actionscript, you can use BindingUtils.bindProperty.

Subject: Re: [flexcoders] dataProvider question
Sure!
my list is defined as follows:
<mx:List id="lstData" width="100%" height="100%"
labelField="@name" ></mx:List>
In my component (well, class) i have the following variable:
[Bindable]
public var MyDataList:XMLList = new XMLList();
then when the application loads and i get the instance of the component,
i call the following:
lstData.dataProvider = mycomponent.MyDataList;
everything looks ok so far, right? then then when i receive a proper
xml, i update it all inside the component:
MyDataList = new XML(myxmlstring).children();
theoretically the lstData should somehow receive notification that the
dataProvider has been updated and refresh itself, right? this doesn't
seem to work. Since this doesn't seem to work we're reserved to throwing
events from the component to the list and rebinding the list when that
event is caught by the gui, but the whole thing is pretty cumbersome and
i think this should work automatically.... what are we doing wrong?
Thank you!

Here is an interesting one, not sure if i'm missing
something or what.
I have a list to show some data.
I also have a component with an xmllist property which
is marked as
[Bindable]
in actionscript, i instantiate that component and bind
this data
property to the list.
When i receive data from webservice, i update the
xmllist of the
component. shouldn't the visual list update as well
since it is bound
to that component's property?
also, i have tried this with an XMLListCollection as
well and same
result. only if i rebind the list to the component's
property do i get
the result.
what i am doing wrong? is this by design? should there
be something
else wired or triggered for the updates to occur
automatically?
thank you in advance if anybody can help in any way,
