page 113. Replace the namespace riabook with mafia

 Page 131, The instructions I would add to page 131 (Gas Station example) after you instruct the reader to add the code snippet so that filtering by message

type (the combo box) will occur.  I believe you should also add an instruction to the user to add
  change="msgList.refresh()"

to the mx:ComboBox control.  Otherwise the user can change the combo box  selection, but the filter will not be applied to the datagrid.

Page 168.  After we wrote the portfolio example, Adobe changed the API and explode radius has to be under 1, for example exploderadius=".2".  Change it to make the pie slice to work properly on the click event. See the source of this application deployed at : http://samples.faratasystems.com/portfolio/PortfolioRpcDemo.html

Page 185,  Listing 5.20 (financialnews2.mxml)  this line:

<mx:XMLListCollection id="newsList" source="{newsFeed.result.channel.item}" />

 
should read

 
<mx:XMLListCollection id="newsList" source="{newsFeed.lastResult.channel.item}" />

 Page 185,

FinancailNews2.mxml exposes a property named security and in PortfolioRPCDemo.mxml  binds the security property to the PortfioloView5’s selectedSecurity property. When the program first runs, no item is selected in the datagrid, so the selectedSecurity property is null and thus the value of security is also null.  Thus this function in FinancialNews2.mxml may not receive a correct value when the application first starts. 

                                                 public function set security(value:String):void {

                                                                this.title = "News: " + value;

                                                                newsFeed.send({s:value});

                                                }

 Thus the call to newsfeed.send will not have a correct value and the HTTPService will fail and the fault event handler will run.  I modified the above function to:

 
public function set security(value:String):void {

                                                                this.title = "News: " + value;

                                                                if ( value.length > 1 )

                                                                  newsFeed.send({s:value});

                                                }

So that the HTTPService send method is only called if value has  a length.  After making this modification the code ran fine from the start.

Page 449. Missing comma between the arguments in the signature of the setFormat function. It has two arguments: dgc and formatString.

Page 548, listing 13.5 – The loadShow method needs to assign a LoaderContext object when calling photo.load so that it checks crossdomain policy files. The following line

photo.load(new URLRequest(photoNode.@source));

should be changed to

var context:LoaderContext = new LoaderContext(true);
photo.load(new URLRequest(photoNode.@source), context );


Page 552, The call to show.playShow is not required in the service result event code.


Page 558, listing 13.11 – The following code

if(sound!=null) { sound.play(gotoTime); }

should be changed to

if(sound!=null) { sound.play(gotoTime * 1000); }


Page 562, listing 13.16 – The bindings in the source attribute of the image component should be updated to reference e4x attributes as follows:

source=" http://static.flickr.com/{data.@server}/{data.@id}_{data.@secret}_s.jpg"


Page 564, listing 13.18 – The bindings in the dataProvider attribute and code in the change attribute of the gallery TileList component should be updated as follows:

dataProvider="{service.lastResult.photos.photo}"

change="selectSlide('http://static.flickr.com/' + event.currentTarget.selectedIte
