Description

Steps to reproduce:
1.Create a default new flex project
2.paste in the following code
<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="vertical"
creationComplete="init();">

<mx:Script>
<![CDATA[

private function init():void

{ txtInput.data = "object"; txtInput.text = "Created at designtime by me"; /** *The order in which the properties are called are * also important. This does work. * First text property is set and then data property. **/ var createdTextInputOk:TextInput = new TextInput(); createdTextInputOk.text = "Created at runtime by flex"; createdTextInputOk.data = "object"; this.addChild(createdTextInputOk); /** *The order in which the properties are called are * also important. This does not work. * First data property is set and then text property. **/ var createdTextInputBad:TextInput = new TextInput(); createdTextInputBad.data = "object"; createdTextInputBad.text = "Created at runtime by flex"; this.addChild(createdTextInputBad); }

]]
>
</mx:Script>
<mx:TextInput id="txtInput" />
</mx:Application>

3.
Run the code

Actual Results:
On the second control created at runtime the crashes with a type error: Error #1009: Cannot access a property or method of a null object reference.
Which is not their in Flex SDK 3.4

Expected Results:
All three textfields should appear on the screen vertically aligned

Workaround (if any):
Assign a value the text property first before setting the data property'

I don't know if it affects more controls that faces this behavior. But this was the first thing we found which broke when we compiled the project with Flex SDK 3.5. Now back to Flex SDK 3.4.

When I read the 3.5 reference more closely, their could be a misinterpretation on my side. I am looking at the property as it has somehow the same purpose as the C# control.Tag property http://msdn.microsoft.com/en-us/library/system.windows.forms.control.tag.aspx
