Hi Robert,
Although on the surface of things our problems were not the same, I'll
bet
it's the same thing somewhere under the hood of the Flex 1.5 compiler
that
is causing these "strange" binding problems to occur.
I keep reading of more and more people that are encountering this
binding/compilation bug.
Have you tried changing your flex-config.xml settings to not keep the
compiled mxml components:
<!-- cache compiled custom components as swo files -->
<cache-swos>false</cache-swos>
And maybe try some of the other cache/compiling settings to see if this
resolves your problem. Compiling may be a little slower but it may be a
better workaround than you currently have.
With the growing number of people having these "mysterious" problems I
wonder if Adobe are going to release an update to resolve them.
Regards,
Simon

Thanks for taking the time for the detailed reply Simon! I WISH it was
validator related. In one instance, I am using a validator but the
first
time I saw this behavior was in a simple MXML file that had 3 lists that
get
populated with 3 separate message types and directly next to the lists
is a
title label and a text area...when the user clicks on a message in any
of
the 3 lists, the title and text area should be updated with the selected
message's title and body content.
The title label and body text area have their text attributes bound to
{ModelLocator.selectedMessage.title} and
{ModelLocator.selectedMessage.body}
respectively and the change listener on all 3 of the lists is simple
ModelLocator.selectedMessage = event.target.selectedItem;
This NEVER works upon first compilation after a fresh server restart.
If I 'touch' the file that contains this message reader component and
refresh my browser...magically, the title and body start appearing when
I
select a message in the lists.
This behavior escapes me and is obviously not conducive to a production
release because I can't exactly go in and 'touch' all necessary files
for
this behavior to be fixed...this should work the first time.
I even have a test button on the message reader page that, upon first
time
server start and app compilation, when I click on a message and the
ModelLocator.selectedMessage object have been set but the title and body
do
not appear, I can click on this button and in an alert body display the
title and the body of the selectedMessage object...I am confirming the
selectedMessage object is getting set with the proper information, the
damn
TextInput components do not want to show it to me though...if I open up
FlexBuilder, open up my MessagerReader.mxml file, hit the spacebar,
backspace and then save it, refresh my browser...magically it all works
properly. It's that initial load that is completely baffling me.
I've tried debugging and because my components are being created as
children
on the fly it doesn't see the breakpoints I'm setting up. I'm at a
loss.
My work around, and this is the kicker, if I take the two fields that
currently, in the same component, reside next to the 3 lists, and wrap
them
up into their own MXML file component and add a COMPLETELY EMPTY
public function set message(m:Message){}
method call in this new wrapped up component and then in the original
message reader component, do this:
<comp:MessageReaderFields width="100%" height="100%"
message="{ModelLocator.selectedMessage}" />
And now, when I select a message, first compilation, 14th compilation,
1st
server restart, 10th server restart, the message title and body field
binding to the ModelLocator.selectedMessage object in my new embedded
component work as they should. Makes sense, right? Nope. Not even a
little bit.
Whatever...looks like I have a work-around for the time being...

Are/have you used a validator with a bound field anywhere in this file?
If so you may be experiencing the same problem as I did. I wasted days
trying to figure out why my Binding had suddenly broken down on several
forms. I was using about 6 or 7 validators per form and the fields in
the
forms were using binding which should be no problem. However the binding
just stopped working and I tried for days to get it to work again. In
the
end I got it working by commenting out nearly all of the mxml content
and
when it started working again I uncommented it and it worked, but then
guess
what - it stopped working again.
Libby kindly gave me some pointers and mentioned that you must use the
"listener" attribute of the Validator tag to explicitly target the field
that you want to validate.
I'm not certain if her solution works but give it a go.
I found a workaround by using just 1 Validator for the entire form and
using
a custom validation function.
<mx:Validator field="checkContact"
validate="contactVH.validateForm(event.validator, event.value)" />
Then your validate function could be:
function validateForm( validator, value ) : Void {
if ( value.firstname=="" || value.firstname==undefined )
{
validator.validationError("firstnameMissing",
"You
must enter the firstname", "firstname");
}
if ( value.lastname=="" || value.lastname==undefined ) {
validator.validationError("lastnameMissing",
"You
must enter the lastname", "lastname");
}
EmailValidator.validateEmail( validator, value.email,
null,
"email" );
if ( value.telephone=="" || value.telephone==undefined )
{
validator.validationError("telephoneMissing",
"You
must enter the landline telephone number", "telephone");
}
if ( value.addrstreet=="" || value.addrstreet==undefined
) {
validator.validationError("addrstreetMissing",
"You
must enter the street address", "addrstreet");
}
if ( value.addrcity=="" || value.addrcity==undefined ) {
validator.validationError("addrcityMissing",
"You
must enter the city address", "addrcity");
}
if ( value.addrpostcode=="" ||
value.addrpostcode==undefined
) {
validator.validationError("addrpostcodeMissing",
"You must enter the post code", "addrpostcode");
}
}
Its not at all efficient because I validate the form on every change of
every field so there is lots of testing going on - but that's because I
need
it to highlight errors as they are being typed or being resolved
This seems to work for me.
If you are not experiencing the Validator/Binding problem - ignore all
of
this!
Regards,
Simon

Have you tried debugging? set a breakpoint in your onResult of the
Command
class and where you explictly set the selectedUser in the model locator.
Once that line has passed, you should stop again then check your text
box to
see if it has the value. I find I get a lot further debugging then using
trace statements. Then repeat the process with the second hit when the
behavior works OK. This should hopefully identify your issue.
