	?page-number?: reader question or request for clarification



Confirmed errors:


(13)  1st code sample, following 2nd paragraph;
<!---I'm valid... weird--->

this should be:

<!--- I'm valid... weird --->


[33]  Last code block;
<cfswitch expression="URL.Action">
should be:
<cfswitch expression="#URL.Action#">


{136}  7th paragraph;
Example reads:

You can also initialize an array using the cfparm tag, as in the following:
   <cfparam name="Grades" type="Array" value="#ArrayNew(1)#>

Should read:

You can also initialize an array using the cfparam tag, as in the following:
   <cfparam name="Grades" type="Array" default="#ArrayNew(1)#">


(167)  first block of code;
<cfif not IsDefined(application.Initialized')>
should read:
<cfif not IsDefined('application.Initialized')>


(206)  3/4 down the page, the password input tag;
The password input tag has an extraneous quote before the maxlength attribute:

<input type="Password" name="Password" size="15" "maxlength="255">
should be:
<input type="Password" name="Password" size="15" maxlength="255">


{217}  Half way down example 8-6, in the CFLOGIN tag;
<cflogin idletimeout="1800" applicationtoken="MyPortal"    cookiedomain="example.com">

should read:
<cflogin idletimeout="1800" applicationtoken="MyPortal"    cookiedomain=".example.com">
(note insertion of dot before example.com)


(377)  1st paragraph;
'Next, we check to see if the directory list operation returned exactly two objects.
This is done using a cfif statement to evaluate the value stored in the RecordCount
query column. If the vlaue of RecordCount is two, we know that the directory is
empty,....'
it should say:
"Next, we check to see if the directory list operation returned zero
results.  This is done using a cfif statement to evaluate
the value stored in the RecordCount query column. If the vlaue of
RecordCount is zero, we know that the directory is empty..."


[527]  Top of page, 3rd line of code.;
In the book, on page 527, line 3, it reads:
xaxistype="scale" yaxistype="scale" sortxaxis="No"

both instances of the word "scale" should be "category". As it is written, ColdFusion throws an error:
For input string: "Greg"

The downloadable source codes for this book do however use the correct syntax.


{550} The entry for alnum should read:
[:alnum:]
Matches any letter or number regardless of the case used.  Using alnum is
the same as specifying [A-Za-z0-9].  Using \w produces a similar result,
but also includes underscores.


{552}
[^[digit:]] is missing a colon (under \D).  
It should look like this:
[^[:digit:]]


[660]  3rd paragraph;
You say that you can include code that makes up a method body within a cffunction and
then give an example where the included method body uses cfargument and cfreturn.
This does not work in ColdFusion as any  code included with cfinclude must be valid
CFML in its own right.  The example that you give causes a ColdFusion error stating
that cfargument and cfreturn must be used within a cffunction.

The example should look like this:

 <cfcomponent displayname="Employee" hint="I'm for working with
    employees">
   <cfproperty name="dsn" type="string">
   <cfset variables.dsn="programmingCF">

   <cffunction name="getEmployee" returnType="any" output="no" access="public">
         <cfargument name="id" type="numeric" required="true">

     <cfinclude template="_methodGetEmployee">

         <cfreturn selectEmployee>
   </cffunction>
 </cfcomponent>


This gets saved as _methodGetEmployee.cfm (the example also inadvertantly leaves off
the file extension):

 <cfquery name="selectEmployee" datasource="#variables.dsn#">
   SELECT *
   FROM employeeDirectory
   WHERE ID=#arguments.id#
 </cfquery>

AUTHOR: Note that I do not advocate coding your CFCs like this, but it is a valid
option if long CFCs are a problem for you.


(665)  2nd code block;
<cfset myObj.setEmployee(argumentcollection=args>
should be
<cfset myObj.setEmployee(argumentcollection=args)>


(697)  9th paragraph;
It says: 
XmlChildern
it should say: 
XmlChildren


(900)  4th paragraph;
It says: 
cfhttp.FileContent
it should say 
cfhttp.fileContent



{1049}  3rd;
Text on page 1049 reads 
<cfset Randomize(GetTickCount())>
it should read:
<cfset Randomize(12345)>
