TextArea ignoring new lines
Hi,
I am working on old Flex3 (Cairngorm2) app.
One of TextArea's there is completely ignoring new lines (Carriage
Return/Line Feed)
and even skips some spaces (others work fine).
Code is pretty simple (well, little simplified here):
<fx:TextArea text="myText" selectable=true change=updateText(event)"/>
...
private function updateText(evt:Event):void {
var event:UpdateEvent = new UpdateEvent(UpdateEvent.UPDATE_EVENT);
event.myText=myText.text;
trace("myText"+event.myText) //added by me
event.dispatch();
}
I have read about weird behaviors of TextArea (skipping or even doubling
some characters) on the net,
but so far could not find anything applicable in that case.
For example, something like myText.text.replace("\n", "\r") doesn't
change anything.
I guess, there is no "\n" there.
If I trace, it returns line without newlines (like:
'startskip1lineskip2linesend;').
But if I copy-paste that line to say another TextArea on the screen (or non
flex Chat app, I would get multiline text:
'start
skip1line
skip2lines
end;
And for various reasons I can't debug that app.
Any idea what might be wrong and how to fix it?
Please help!
TIA,
Oleg.
P.S.: App connects to SPs in the Database via Web Service. No BlazeDS.

Are there \r or \n in the strings? Try using getCharAt() to examine the
string. If there are, then somehow, the multiline flag got turned off on
the internal text widget.

I can see '\' characters in myTextArea.text. Should I try replacing them
with '\n' or that won't help?
As I said, that TA doesn't display new lines. Any TA properties can help?
TIA,
Oleg
