[flexcoders] Re: resizing a textArea to fit Text of the container.

TextField has a problem calculating numLines if text contains CR/LF
symbols.

  or something.

  Do you have a lot of whitespace before and after those 3 lines of
  text? You could set 'condenseWhite' to true, that might help.

 Hi,
 
 Take a look at PrintTextArea in 
 http://code.google.com/p/flexreport/source/browse
 http://code.google.com/p/flexreport/source/browse  
 (trunk/flexreport/org/print/PrintTextArea.mxml). It's not exactly for 
 what you want (since it's pageable) but you can see how I get the text 
 metrics.
 
 Hope this helps,
 
 Frederico Garcia

Still, I don't know why you've got such a difference in your case.

I am using the following thing: 
override public function set text(val:String)
{
  super.text = val;
  for (var i:uint = 0; i  super.text.length; i++)
  {
   if (super.text.charAt(i) == '\r' || super.text.charAt(i) == '\n')
   {
  m_iParagraphNo++;
} 
  }
}

and then use iParagraphNo in set height() - adding the corresponding
number of extra lines.

Cheers,
Dmitri.
