Recently I needed to fix a bug where a mx:TextArea was always dirty. The reason was a text with line breaks like:
“This is a text.
This is another text.”
In database this text was stored as char(255) like “This is a text.\r\n\This is another text.”
Here is the original code:
<mx:TextArea id="commentInput" height="50" maxChars="255"
text="{personModel.person.comment}" width="100%" tabIndex="20"/>
After some time I figured out that the reason the form was dirty was HTML text. So to fix it I changed text with htmlText:
<mx:TextArea id="commentInput" height="50" maxChars="255"
htmlText="{personModel.person.comment}" width="100%" tabIndex="20"/>
But, this solution gave an unaxpected side effect. This was possible to render only one person, if I tried to render the other one in another tab, same data was visible for both persons.
That’s why I needed to solve the problem with replacing:
<mx:Script>
<![CDATA[
public function get comment():String {
var crlf:String = String.fromCharCode(13, 10);
var regEx:RegExp = new RegExp(crlf, "g");
return _kommentar != null ? _kommentar.replace(regEx, "\r\r") : '';
}
]]>
</mx:Script>
...
<mx:TextArea id="commentInput" height="50" maxChars="255"
text="{personModel.person.comment}" width="100%" tabIndex="20"/>
