[flexcoders] Re: Weird Validate Binding problem
This may or may not help. It is a combination of the examples in the
help for DateValidator and Binding:
?xml version=1.0 encoding=utf-8?
!-- Simple example to demonstrate the DateValidator. --
mx:Application xmlns:mx=http://www.adobe.com/2006/mxml;
mx:Script
import mx.controls.Alert;
/mx:Script
mx:DateValidator source={dob} property=text
allowedFormatChars=/
trigger={myButton} triggerEvent=click
valid=Alert.show('Validation Succeeded!');
invalid=Alert.show('Thats not a date!!');
required=true/
mx:Binding source=Date.parse(dob.text).toString()
destination=myText.text/
mx:Panel title=DateValidator Example width=75% height=75%
paddingTop=10 paddingLeft=10 paddingRight=10
paddingBottom=10
mx:Form
mx:FormItem label=Enter date of birth (mm/dd/):
mx:TextInput id=dob width=100%/
/mx:FormItem
mx:FormItem
mx:Button id=myButton label=Validate /
/mx:FormItem
/mx:Form
mx:Text id=myText/
/mx:Panel
/mx:Application

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!

I may be wrong but I didn't think you could use a binding with a
function. Try removing the Date.parse function from your binding tag...
mx:Binding source={birthdayTI.text}
destination=tideContext.user.birthday/

[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?
