UNCONFIRMED  errors and comments from readers: 


(14)  First example (middle of page);
The xmlns attribute line for xul ends with an ">" character that shouldn't be there.
(The next line also ends with an ">".)



(32)  line 3;
page 32 shows line as locale,install,resource:/chrome/xfly/locale/

page 152 shows the same line as reading
locale,install,resource:/chrome/xfly/locale/en-US/



(32)  middle of page;
Application of chapter 2 cannot be launched, the XML-Parser lists the following
error: undefined entity <label id="xlabel" ... (the opening bracket is underlined as
the undefined entity).



[32]  under heading 'macintosh launch';
Using the os x version of mozilla, all this does is write the contents of the text
file into the browser window. (-chrome chrome://xfly/content/) ive tried both methods
suggested, dropping the text file on the mozilla icon and changing the file creator
to "MOZZ". Needless to say I still haven't gotten the app to launch using the methods
described. I've had no success using the unix method either, although I'm not sure if
that applies to os X. I have found some errors in my typed files and there was a
parsing error in the xfly.xul file that i corrected. I find that the book was
probably written for Mac OS 9, from what i can tell, the files need to go into the
chrome directory that you can only access as root, seeing as that is where the
installed-chrome.txt file is located.  These files need to be either created with a
terminal app like pico or vi or done in a graphical editor and then moved into this
directory from the terminal, neither is a trivial procedure and the book sh!
ould probably mention that.


(35)  First example;
In the example, this line:

secondLevelNodes[I] = docEl.childNodes[i];

might have an error: should the second [i] be [I]


(37)  Third paragraph (paragraph under example);
In this sentence, should "and be displayed" be "and will be displayed" or "and is
displayed"?

"In Example 3-2, the entity in the header title, &lHeader;, resolves to  Languages
and be displayed above the individual preference panel page."


(38)  Example 3-3;
This attribute seems to be missing the quotes around its value.  My Acrobat Reader is
also showing it in Italics, for some reason:


(38)  example 3-3 line 6;
(it would appear that) the line should read:
xmlns="http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul"


{38}  example 3-3 line 13;
There is no closing tag for the <image> tag; that is not </image>


(40)  Second example (follow-on to example 3-4);
In this section of the code, the last label should probably be "Print" instead of
"Open":

<toolbarbutton id="newfileBtn" label="New" oncommand="doNew();" />
<toolbarseparator />
<toolbarbutton id="openfileBtn" label="Open" oncommand="doOpen();" />
<spacer flex="1" />
<toolbarbutton id="printBtn" label="Open" oncommand="doPrint();" />


(123)  Code on the top of the page;
1) setAttribute is spelled as "setAttributte" (with 2 t's)
2) "checked" should be "disabled"


{136}  Example 5-11;
The example contains:

<form name="form">
  <input type="button" value="Play Sound" onclick="sample.play(url);">
<form>

The form tag should have been closed with </form>.


(143)  DirUtils XUL example;
The example contains:

<script type="application/x-javascript" src="chrome://jslib/content/io/dirUtils.js"
/>

This will fail to define DirUtils unless it is preceded by:

<script type="application/x-javascript" src="chrome://jslib/content/jslib.js" />
