23719 - Common Dialogs not inserting linebreaks properly

Status: VERIFIED DUPLICATE of bug 21418

(SeaMonkey :: UI Design, defect, P3)

Description

[Ben Goodger (use ben at mozilla dot org for email)]

"\n" in alert() strings are being ignored, and a raw "n" being inserted.

e.g. alert("Foo\n\nBar") should display an alert containing:

+-------------+
|  Foo        |
|             |
|  Bar        |
|-------------|
|    [ OK ]   |
+-------------+

but instead displays

+-------------+
|  FoonnBar   |
|-------------|
|    [ OK ]   |
+-------------+

I looked at the code in commonDialog.js, and it seems that the code does this:
param = window.arguments[0].QueryInterface(
Components.interfaces.nsIDialogParamBlock  );
then gets the message text in the alert() call like this:
var messageText = param.GetString( 0 );

However dumping the messageText to the console shows that the "\n"s have been
converted to "n"s, and the code that follows this does not work, because it
assumes the string contains "\n". So it seems that something in the back end is
converting \n to n when it shouldn't be, resulting in the improper display.
