[flexcoders] Re: ComboBox Problems
it's got a lot of mess and debug junk, but:
public function addedToStageHandler():void
{
Application.application.log.text += Got Add
event\n;
Application.application.log.text += MONTH = +
monthCB.selectedIndex + \n;
Application.application.log.text += DAY = +
dayCB.selectedIndex
+ \n;
Application.application.log.text += YEAR = +
yearCB.selectedIndex + \n;
if (date != null)
{
dispatchEvent(new Event(Event.CHANGE, true));
dispatchEvent(new Event(Event.RENDER, true));
Application.application.log.text += date
is NOT null\n;
monthCB.dispatchEvent(new Event(Event.CHANGE,
true));
dayCB.dispatchEvent(new Event(Event.CHANGE,
true));
dayCB.dispatchEvent(new Event(Event.RENDER,
true));
yearCB.dispatchEvent(new
Event(Event.CHANGE,true));
Application.application.log.text += 3 MONTH = +
monthCB.selectedIndex + \n;
Application.application.log.text += 3 DAY = +
dayCB.selectedIndex + \n;
Application.application.log.text += 3 YEAR = +
yearCB.selectedIndex + \n;
}
else
{
Application.application.log.text += Date
IS null\n;
}
}
So every time it's added to the stage, I'm seeing what the values are,
and the values remain constant and correct, just the option that the
comboboxes are showing are incorrect.

Subject: [flexcoders] ComboBox Problems
Hey all.
Having a silly problem with 3 comboboxes and can't seem to find
anything very helpful via google.
I'm creating a user registration wizard with multiple pages that
contains a custom component. The custom component is a date selection
component consisting of 3 combo boxes (month, day, year). They are
all populated with simple arrays as the dataProvider.
Every thing works perfectly except. . .If you select your date (DOB in
this case) and go back to a previous page in the wizard when you
return to the page with the DOB control, the comboboxes are showing
the prompt again. The selectedIndex/Item !IS! correct, it's just not
displaying the that correct value. They're not being reinstantiated,
etc.
I've tried firing off CHANGE and RENDER events on the comboboxes but
nothing (programatically) will force them to show the value they have
for selectedIndex that I've been able to find.
Anybody have any pointers on this one? Seems silly to me that the
default behavior wouldn't be to always show the current selectedIndex
*shrug*.
Thanks!
Gerald
[flexcoders] Re: ComboBox Problems
The values are correct, and I've tested explicitly setting them to see if that makes a difference. The combobox objects aren't reinstantiating, just what they're showing is switching back to default and I can't figure out a way to tell them to display the current selectedIndex.

[flexcoders] Weird Validate Binding problem
Hello all!
I have a TextInput field that is to accept a date. There is a date validator
attached to the
field and the text property of the date field is bound to a property in another
field. Here's
the code:
mxml:
mx:DateValidator id=validateBirthdayTI
source={birthdayTI}
property=text
required=true/
mx:Binding source={Date.parse(birthdayTI.text)}
destination=tideContext.user.birthday/
Actionscript:
formIsValid = formIsValid validate(validateBirthdayTI);
When the validator runs, I get the following error when doing a try/catch,
otherwise it fails
silently.
The source attribute must be specified when the property attribute is
specified.
This seems to say that the source attribute for the validator isn't correct,
but I don't see
anything wrong with it (and other fields/properties are fine). It also seems
to somehow be
tied in to the binding as if I comment out the binding it works (and validates)
just fine. I
have a feeling I'm running up against one of those very strange Flex errors
that don't mean
what they say exactly ; )
Any help is very much appreciated, I've been beating on this thing off and on
for a week
and am getting pretty frustrated.
Thanks!

[flexcoders] Re: Weird Validate Binding problem
That was how it was originally (same error). Thought I might be having a type
issue so
added the Date.parse(). You can actually do it if it's specified in the braces
({}). From http://www.adobe.com/devnet/flex/quickstart/using_data_binding/ :
Note: The source property of an mx:Binding tag can contain curly braces. When
there
are no curly braces in the source property, the value is treated as a single
ActionScript
expression. When there are curly braces in the source property, the value is
treated as a
concatenated ActionScript expression.
Any other ideas?

I may be wrong but I didn't think you could use a binding with a

[flexcoders] Programatically deselecting tree branch objects
Good morning all,
I'm trying to set up a tree control so that branch items open and close
on select just as if somebody had clicked the twirly.
I've got everything taken care of but I need to find a way to
programatically deselect the branch item.
Here's the code problem:
In my Tree change event handler
public function handleTreeChangeEvent(event:Event):void
{
//some code
if (selectedVideoId != '')
{
trace(selectedVideoId + is the selected video);
}
else
{
if (videoTree.isItemOpen(selectedVideo))
{
videoTree.expandItem(selectedVideo, false, true);
// I now need to deselect this tree item
}
else
{
videoTree.expandItem(selectedVideo, true, true);
// I now need to deselect this tree item.
}
}
}
See the // comments for details on what I'm trying to do.
I very much appreciate any light anybody can shine on this, I've been
beating up google and the API docs for the last few hours with no
results.
Thanks!!

[flexcoders] Re: Programatically deselecting tree branch objects
for posterity, I finally came up with a decent solution.
To programatically deselect an item from a Tree:
treeObjectName.selectedItem = null;
Hope that helps somebody at some point.
