Day 3, Exercise 4

I am working on the exercise pdf "Using XML With E4X" and
right at the beginning it says: "26. From the events folder open
OpenSelectEvent.as."
In my Events folder I have an
OptionSelectEvent.as file. Is this a typo in the PDF
instructions, or am I missing a file?

It is a typing error. I found a couple others in there, too.
I was able to complete the lesson successfully.

Errors in Day 3 exercise

I'm doing this exercise:
http://www.adobe.com/devnet/flex/pdfs/using_remote_object_to_send_data_to_the_server.pdf
In the first part, you are told to delete the previous
project but not the
contents.
Then you are told to create a new project with this path:
C:\adobeFlexTraining\AdobeODT
Further on, you are told to open ReservationData.mxml which
was in the old
project. However, since the path to the old project was
C:\adobeFlexTraining\_workspace\AdobeODT and the new project
eliminates the
_workspace folder in the path, ReservationData.mxml (which
was in the first
project) is unavailable.
Error? Or have I misunderstood something?

Day 2, Exercise 4 Error

I am getting an error on exercise 2.4 when trying to run the application with the network monitor enabled. Copied directly it reads:

As far as specific details on the steps I have taken, they are identical to the instructions on the exercise page. I am using the trial version of the Flash Builder 4.6 premium package. I deleted all the files from my 'Day2' workspace and re-imported them to try again from scratch and got the exact same error each time.

Sure, here is the code. I have also added it as an attachment. Thank you for your help.

Day 1 Exercise 3

Hi,
When I try to load assets/roomList.xml, I get a Security
Sandbox Violation.
What do I do?
thank you!
Chris

never mind, i added my project folder to the Security
Settings Manager and all is well...duh...

Day 2, Exercise 6 - Bindable ?

Hi,
The variable is bindable:
[Bindable] public var selectedOptions:ArrayCollection;
So, if I set the list data provider to this variable, like:
<mx:list id="thelist" dataProvider="{selectedOptions}" />
That means any change on the variable value will impact to list.
The list will update automatically if bind variable value change.
( That's what I understood "Bindable" base on data grid example )
Why this seems not working ?
And we need add init() ( trigger on creationComplete )
            private function init():void {
                selectedOptions.addEventListener(CollectionEvent.COLLECTION_CHANGE, addToList);
            private function addToList(event:CollectionEvent):void {
                thelist.dataProvider = selectedOptions;
So, we are modify the dataProvider of list every time when the variable value changed.
Why simply set the dataProvider and make the variable [Bindable] didn't work ? ( <mx:list id="thelist" dataProvider="{selectedOptions}" /> )
Thank you for your help.

I think sometimes if the objects in the collection are complex, like an instance of a class that have properties, if those properties in the class change the binding doesn't work unless you explicitly set up binding in the class.

In day 4, video # Creating "pages" with Flex states doesn't work

i can't open video training http://www.adobe.com/devnet/flex/videotraining in day 4. it's name( Creating "pages" with Flex states ) doesn't work, it report error. supporter can look it and solve problem

Wrong file in the "Populating an ArrayCollection with retrieved data" exercise

In the "Populating an ArrayCollection with retrieved data" there is a file ex2_04_starter.zip, which contains ex2_04_solution.mxml file and should contain ex2_04_start.mxml, right ?
Great videos! Thank you!

Hi Burpix,
Looks like the link for the starter file within the exercise is linked to the wrong file. If you pull the project archive for Day 2 you will get all of the starter & solution files and video transcripts for all of Day 2 exercises. The starter file for ex2.04 is correct if download it from the project archive zip. Adobe will be fixing the link within the exercise later but for now you can pull the correct starter file from the project archive zip.

Why are Java files listed as needing repair in Disk Utility?

Why are Java files always listed as needing repair in Disk Utility?

FrenchToast wrote:
Baltwo, bull's eye, as always!
X423424X's question is pertinent too: you usually need to repair permissions after some major upgrade or update, not on a regular basis. Is there a particular reason why you'd often try to repair permissions? Here's more on the subject.
Repairing permissions after an update or upgrade is harmless, but I would question the need to do it even there. The Apple update itself should set the correct Permissions. I still do this, really as a hangover from Tiger days -- not certain it was really ever needed there either -- and because it's a habit that's hard to kick, but it's never found anything to repair...but for one buggy exception, which was the 10.5.8 Combo update. Running it once and then repairing Permissions created a real error. It was discovered the Combo needed to be run twice back to back and then Permissions repair. In fact, one would have been better off not running Permissions for that update to begin with. There it wasn't harnless.
https://discussions.apple.com/message/9968141#9968141
BTW, even Flash updates, which always used to set incorrect Permissions, are coming in clean these days.

A wrong effect in the inks with invisible sprites

Hello,
I am watching a wrong effect associated with the inks in a sprites.
I have several sprites located in the score which are overlapped
Specifically are images irregular. To avoid that when the user put the mouse on one of the areas the mouse interact with another area I use "Background transparent" ink and working properly.
But sometimes I put in that place a sprite (to have it available if I touch a button) and as I do not want to be seen on stage I put it invisible.
It´s strange, but after leaving that sprite invisible, without modifying the "Background transparent" ink, it don´t work if I put the mouse on the sprite.
The resulting effect is as if the ink used were the “Copy" ink.
Do you think something to avoid this problem?

Apple watch resting calories seem far too high

I've had the apple watch since the 24th, and I've worn it continuously until bedtime. All of my metrics are accurate (height/weight).
My Resting Calories (found in the iPhone activity app by swiping left under the move row) are listed as 3600 Cal. This seems incredibly high to me. My BMR is 2100 Cal, as calculated here: http://www.myfitnesspal.com/tools/bmr-calculator
I've used other BMR sites and they all give me a similar number.
Is anyone else having this issue? I can't comprehend how it could be so high. If I ate 3600 Cal in one day (without exercising) I would be gaining weight rapidly!

No.
