mx:TextInput bug from Flexosaurus

Nearly five months ago I noticed mx:TextInput's bug. The following steps will reproduce the bug.

In the Application 1

- Enter some long string in the mx:TextInput e.g. "asd asdsa sadsadsa sadsad asdsa"

- Click on the "Button" button(it is setting text in the mx:TextInput to "yes")

- You will not be able to see the text in the mx:TextInput, you will be able to see the text if you e.g. click on the mx:TextInput

Application 1

<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml"
 width="300" height="50" layout="absolute">

 <mx:Script>

  <![CDATA[

   private function clickBtn(event:MouseEvent):void
   {
    txtInput.text = "yes";

   }
  ]]>

 </mx:Script>

 <mx:Button id="btnSubmit" x="178" y="10" label="Button"
  click="clickBtn(event)"/>
 <mx:TextInput id="txtInput" x="10" y="10"/>

</mx:Application>

There is a few ways for fixing this problem. Here is one of them. We will create custom text input component and override public function set text(value:String):void function. In the text setter we will call initialize mx:TextInput text property (super.text = value;) and then we'll just bring the cursor to the begging.

Reproduce the bug for the Application 2 and you will be able to see the text.

Application 2

<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml"
                    xmlns:ns1="*"
 width="300" height="50" layout="absolute">

 <mx:Script>

  <![CDATA[

   private function clickBtn(event:MouseEvent):void
   {
    txtInput.text = "yes";

   }
  ]]>

 </mx:Script>

 <mx:Button id="btnSubmit" x="178" y="10" label="Button"
  click="clickBtn(event)"/>
 <ns1:CustomTextInput id="txtInput" x="10" y="10"/>

</mx:Application>

CustomTextInput.as

package
{
 import mx.controls.Alert;
 import mx.controls.TextInput;

 public class CustomTextInput extends TextInput
 {
  public function CustomTextInput()
  {
   super();
  }
  
  override public function set text(value:String):void
  {
   super.text = value;
  
   // Bringing cursor to the beginning
   setSelection(1,1);
  }
 }
}
