I think you're right that binding may not be the best solution here.
What if your TextInput looked like this:
<mx:TextInput id="cdc" width="35" text="{
CTabellaSviluppoVO(vosviluppo[key]).tga1sv==undefined ?
'':CTabellaSviluppoVO(vosviluppo[key])['tga'+r.currentIndex+'sv']}" />
That would get the proper text from your array based on the key into the
TextInput I think.
Now you want to copy it back, you can either use a for loop for all fields
that would be triggered by a button:
function updateVO()
{
for (var i=0; i<cdc.length; ++i)
{
vosviluppo[key]['tga'+i+'sv'] = cdc[i].text;
}
}
Or if you didn't want the button you could maybe use the change event on the
text input (or valueCommitted) to do the copy:
<mx:TextInput ... valueCommitted="
vosviluppo[key]['tga'+event.target.getRepeaterIndex()+'sv'] =
event.target.text" />
Does that make sense? Hopefully we're talking about an independent array
here. Remember, if your VO is also being shown in a DataGrid or List you
may want to use the editField method on the dataProvider as opposed to
changing vosviluppo[key] directly.

Subject: [flexcoders] Binding we are confused
sorry Matt, but i haven't understand you can explain me please? :-(
I have also post this question in Macromedia Italia tech (Enrique)
but without success because if you look our binding , it's ok work, but
i think that there are a better solution than ours.
I make you an example that yesterday it has aroused a some of problems.
I have an array :
<mx:HBox>
<mx:Repeater id="r" dataProvider="{taglie}" recycleChildren="true">
<mx:FormItem label="{r.currentItem}" required="{r.currentItem!=tg_base}" >
<mx:TextInput id="cdc" width="35" text="0" />
</mx:FormItem>
</mx:Repeater>
</mx:HBox>
These TextInput they would owe to be to bind with our vo object (see
attachment). but in progressive mode, for example
cdc[0].text=vo.tga1sv
cdc[1].text=vo.tga2sv
......
cdc[10].text=vo.tga10sv
....
and when user chage some TextInput and click theUpdate button
we have to hold the object VO syncronized .
Now we are using a circular binding , but ok work, but throws warnings
in the second line, and and honestly i'm worried, in what I think there
will be a valid alternative,
<!--Taglie -->
<mx:Binding
source="{CTabellaSviluppoVO(vosviluppo[key]).tga1sv==undefined ?
'':CTabellaSviluppoVO(vosviluppo[key]).tga1sv}"
destination="cdc[0].text" />
<mx:Binding source="cdc[0]"
destination="CTabellaSviluppoVO(vosviluppo[key]).tga1sv" />
yesterday in Macromedia Tech Italy have recommended us to use a circular
binding unfortunately, but in my case it doesn't seem you an ugly
solution, and besides I receive some warnings therefore
I think about having adopted a wrong solution for my case.
Any suggestion it's MUCH MUCH appreciate.
