Then when you want to update to the server the model is current.<mx:TextInput id="userName" 
   text="{model.userName}   change={model.userName = userName.text}"/>then you can submit the model with userName VO to the server with out assigning anything.Peace, Mike

Thanks for that informative post - 
 
I guess I shouldn't post such (not dumb) but simplistic 
questions - I know better than that :)
 
Since Flex 2.0 has added such intuitive new features - one 
of those being the ability to directly find a Value within a Grid or List 
control, without having to Iterate through the values inside a Loop, that 
DataBinding may have had some enhancements to it as well.
 
I think it would be neat, to have an optional type of 
Binding scenario - in which the data flows both ways 
automatically...
 
In my case, I will just take the most typical path, and 
create 2 sets of Binding Commands - one that assigns the ValueObject properties 
to all my controls, and one that assigns all my control properties to the 
ValueObject.  That should take care of any changes that are 
made in either direction...
 
I was just expecting too much, from the Binding features of 
Flex - and just have to continue to do it the traditional 
way...
 
Thanks again for all your help -
 
Mike

Bind your outgoing data to a model and submit that to the server:

<mx:Model id="infoModel">
<info>
<text2>{text1.text}</text1>
<text2>{text2.text}</text2>
<info>
</mx:Model>

Send it to the server via an HTTPService:

<mx:HTTPService 
id="saveAny"
method="POST"
url="" href="http://yourserver/process.a" target="_blank" >http://yourserver/process.a"
useProxy="false"
showBusyCursor="true">
</mx:HTTPService>

Send like this:
saveAny.send(infoModel);


Bind the incoming like this:

<mx:Form width="50%" height="100%">
<mx:FormHeading label="Standard 
Info"/>

<mx:FormItem 
label="Text 1">
<mx:TextArea 
id="text1" text="{generalInfo.lastResult.response.info.text1}"/>
</mx:FormItem>

<mx:FormItem 
label="Text 2">
 <mx:TextArea id="text2" 
text="{generalInfo.lastResult.response.info.text2}"/>
</mx:FormItem>

<mx:Form>

To a service like this:
<mx:HTTPService 
    id="generalInfo" 
    url="" href="http://yourserver/get" target="_blank" >http://yourserver/get"
    useProxy="false">
</mx:HTTPService>


I use php, here's how I return the data. I put everything in an associate 
array then output it with a function:

$row['text1'] = "some data";
$row['text2'] = "some more data";

print "<?xml version=\"1.0\" ?>\n";
print "<response>";
print namedAssocToXml('info', $out);
print "</response>";

function namedAssocToXml($rowname, $attributes) {
$output = 
"<$rowname>\n";
foreach 
($attributes as $name => $value) {
if 
(is_array($value)) {
if 
(is_numeric($name)) {
$output .= 
namedAssocToXml('row', $value);
} 
else {
$output .= 
namedAssocToXml($name, $value);
}
}
else {
$value = 
str_replace("<", "&lt;", $value);
$value = 
str_replace(">", "&gt;", $value);
if 
(is_numeric($name)) {
$output .= 
"<item>" . $value . "</item>\n";
} 
else {
$output .= 
"<$name>" . $value . "</$name>\n";
}

}
}
$output .= 
"</$rowname>\n";
return 
$output;
}


I think using HTTPService is the older model for doing things. With FDS you 
can do a lot of cooler things, but hopefully that will get you 
started.

  Or must I do

  ValueObject, just prior to sending the Variables over to the 
  server?
   
  i.e.
   
  myValueObjectVO.propertyOne 
  = textFieldOne.text;
  
  myValueObjectVO.propertyTwo 
  = textFieldTwo.text;
  
  myValueObjectVO.propertyThree 
  = textFieldThree.text;

  No, binding 
  is only one-way, you'll need to set up the 2-way yourself.

  [flexcoders] Don't bindings work both ways??
  
  
  
  
  

Hello 
  All,I 
  have a Form with several fields - and those fields are all bound to 
  aValueObject 
  (using the Curly Braces method).

After 
  doing my database calls, etc., my Form populates beautifully withall 
  the values. However, if I edit any of those fields on the Form, andthen 
  send the same ValueObject back to the server, nothing is changed -it's 
  as if I didn't make any changes to the Form itself.

It 
  was my understanding, that once a Binding Relationship is created,that 
  any changes (either in the Model itself, or the Fields that aretied 
  to the Model) will update in both directions.

Is 
  this not true, or am I missing something?

Thanks 
  all for your help,Mike
