Problem with "Using Validators and Converters" example

Hi,
I am doing the Validatoris an Converters tutorial and I can't get it correctly executed.
In step 9, I double click on textField1 and the systems goes to textField1_processValueChange function instead of textField1_valueChangeListener.
I added the code of step 10 as a separate method and after executing it there is no error message. Please help. Thanks,
I wish these examples where a little more of dummies: step 2 toke some time because you don't say "In the properties window". Please look the tutorials with people that does not know anything about the Creator.
Also I wish you had a step by step tutorial with "About Components", "About Message Components", and "About Converters". Just reading , I did not grasp anything, so I prefer to create a project with these tutorials.
Do I need to learn JSF in order to understand and use Creator? It seems as I read the tutoriasl you assume to much. I found that Cay Horstmann's Core JavaServer Faces book is downloadable at http://horstmann.com/corejsf/
Thanks for your input,
Lorenzo Jimenez

Hi,
You may find our book, Java Studio Creator Field Guide, helpful for a more gentle introduction to Creator and JSF components. We don't assume that you know JSF or even Java. We also have step-by-step instructions for building projects.
Here's the link to our website:

(You can download Chapter 2, which is the basic introduction to Creator.)
Hope that helps.

I have two Iphones with different email addresses sharing one Apple ID. Will that cause problems with using messaging and FaceTime?

I have two Iphones 5 with different email addresses sharing one Apple ID account.Both are using IOS 8.
I would like to set up a new Apple Id for one of the phones and remove it from the old account.
If I do that, can I move all of the purchased apps and songs to the new Apple account?
Also, will sharing one Apple ID account with two devices cause problems with using messaging and FaceTime?

Sharing an iCloud account between two devices can be done without causing issues with iMessage and FaceTime, just go into Settings for each of these functions and designate separate points of contact (i.e. phone number only, or phone number and unique email address). While that works, you'll then face the problem where a phone call to one iPhone will ring both if on the same Wi-Fi network -- but again, that can be avoided by changing each phone's settings.
Rather than do all that, don't fight it -- use separate IDs for iCloud. You can still use a common ID for iTunes purchases (the ID for purchases and iCloud do not have to be the same) or you can use Family Sharing to share purchases from a primary Apple account.

The program does the job but there are 2 questions. I am using a scrollviewer and each time the tab increases the canvas size increases and this is reflected in the scrollview bar getting shorter.
Question 1)
I set the scrollview1 height to 200 ,which was obtained by trial and error, increasing causes the extents to go outside the box etc,
the window height was 300 , is it possible to automatically set the scrollviewer height.
Question 2)
Is it possible to put the canvas and scrollviewer into the XAML I tried but failed
Note: the relevent code to the above questeions is between XXXXX... and YYYY...

>>the window height was 300 , is it possible to automatically set the scrollviewer height.
You should not specify an explicit height if you want an element to fill the available space. Just set the VerticalAlignment property to Strecth (which is the default value for a ScrollViewer:
Canvas_Paint(ref canvas1); // Canvas_Paint defines the background color of "canvas1"
scrollview1.VerticalAlignment = VerticalAlignment.Stretch;
canvas1.Height = 400 + 400 * count;
scrollview1.Content = canvas1;
tab.Content = scrollview1;
//YYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYY
// insert tab item right before the last (+) tab item
_tabItems.Insert(count - 1, tab);
return tab;
>>Is it possible to put the canvas and scrollviewer into the XAML I tried but failed
Well, you could define the ScrollViewer, i.e. the root element, as a resource and then add access it from the AddTabItem() method like this:
<Window x:Class="WPFDynamicTab.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Title="Dynamic Tab" Height="300" Width="527" WindowStartupLocation="CenterScreen">
<Window.Resources>
<ScrollViewer x:Key="sv" x:Shared="false">
<Canvas Height="800">
</Canvas>
</ScrollViewer>
</Window.Resources>
<Grid>
<TabControl Name="tabDynamic" ItemsSource="{Binding}" SelectionChanged="tabDynamic_SelectionChanged">
<TabControl.Resources>
<DataTemplate x:Key="TabHeader" DataType="TabItem">
<DockPanel>
<TextBlock Text="{Binding RelativeSource={RelativeSource AncestorType=TabItem }, Path=Header}" />
</DockPanel>
</DataTemplate>
</TabControl.Resources>
</TabControl>
</Grid>
</Window>
private TabItem AddTabItem()
int count = _tabItems.Count;
// create new tab item
TabItem tab = new TabItem();
tab.Header = string.Format("Tab {0}", count);
tab.Name = string.Format("tab{0}", count);
tab.HeaderTemplate = tabDynamic.FindResource("TabHeader") as DataTemplate;
// add controls to tab item, this case I added just a canvas
ScrollViewer scrollview1 = this.Resources["sv"] as ScrollViewer;
Canvas canvas1 = scrollview1.Content as Canvas;
canvas1.Name = "canvas1";
Canvas_Paint(ref canvas1); // Canvas_Paint defines the background color of "canvas1"
scrollview1.VerticalAlignment = VerticalAlignment.Stretch;
canvas1.Height = 400 + 400 * count;
scrollview1.Content = canvas1;
tab.Content = scrollview1;
// insert tab item right before the last (+) tab item
_tabItems.Insert(count - 1, tab);
return tab;
It may not provide that much benefits in this scenario though since you are setting the height and the background of the Canvas dynamically but it is indeed possible.
Hope that helps.

Problem with using iPhoto and Preview

I needed to resize a picture in iphoto. I opened it in Preview and resized it. At the top of the Preview window, where the file name is, I wanted to rename it so it would be easier to find. It let me do that. I closed the picture. When I went to open it in iphoto, the thumbnail is there, but when I double click on the thumbnail, the exclamation mark appears. I cannot open it in Preview either. It says the size is 0. It also still shows the original filename. I can't find the picture in Finder, using either the original or new name. From what I've found online, it seems I've changed the pathway. I can't find anything to rename/change it back. Help!!!! (I repeated the process with a picture I didn't care about. Somehow I changed the name back and am able to open it again in iphoto. I can't for the life of me remember what I did!!!! Both pictures, with the original filename and the new one are in Preview, but I can't open the one with the new name.)
(If renaming the picture means you can't access it anymore, why is that a feature?)

Problem with using CNEX0027 and BOM

Hi Experts,
I need your help. If I activate user-exit CNEX0027 the BOM item is not transfered into components list of PM order. When UE is not activated the BOM item is transfered correctly.
I was looking for a note but it did not avail.
How can I solve this problem?

Yura,
Activate the user-exit, but comment-out your code (i.e. no active ABAP code).
Then re-test.
I'm guessing that its your code causing the problem which is why I asked for you to post the code so we can see for ourselves..

The warranty for the iPhone is not and has never been International.
Warranty and support are ONLY valid in the country of origin. The only exception is the EU where the entire EU is treated as one country.
If the device will be used in India, buy it in India.
An unlocked iPhone will work on any supported GSM carrier world wide. The LTE portion of a US purchased, unlocked iPhone is unlikely to work outside North America as it does not support the appropriate bands used in other countries.

Hello apple
I have the problem with my iPhone and my friends have this problem too.
My iPhone have the problem about calling and answer the call. When I use my iPhone to call I can't hear anything from my iPhone but the person that I call can answer it but when answer both of us can't hear anything and when I put my iPhone to my face the screen is still on and when I quit the phone application and open it again it will automatic call my recent call. And when my friends call me my iPhone didn't show anything even the missed call I'm only know that I missed the call from messages from carrier. Please check these problem I restored my iPhone for 4 time now in this week. I lived in Hatyai, Songkhla,Thailand and many people in my city have this problem.
Who have this problem??

Apple isnt here. this is a user based forum for technical questions. The solution is to restart, reset, and restore as new which is in the manual after that get it replaced for hard ware failure. if your within your one year warranty its replaced if it is out of the warranty then it is 199$

Problem with use of COM+ Transaction and DB Transaction

Problem with use of COM+ Transaction and DB Transaction
We build a Web site that use sometime COM+ Transaction and sometime DB
Transaction. If we use a COM+ Transaction and a few seconds later we try to use
a Database Transaction (OracleConnection.BeginTransaction), we get the error
Connection is already part of a local or a distributed transaction
Of course the error does not produce everytime; it takes some try before we get
the problem. And of course, if i use pooling=false on the connection string,
the problem does not appear.
i run the Web page
and push the COM+ Transaction and DB Transaction one after the other for some
times and the problem should appear.
Environment: Windows server 2003, .Net Framework 1.1, ODP.Net 9.2.0.401,

Hello Khayalh,
You should be able to link your phone number by following the steps in the article below. From your iPhone, sign out of FaceTime and iMessage and then sign back in and it should link. Check in the Start Conversation With and I Can Be Reached at section in iMessage and FaceTime respectively.

I bought my iphone unlocked from carephone warehouse, I had a problem with the phone and apple swapped it over but they locked it to tmobile!!! what can i do?? I have changed contracts and can not use my phone!

I bought my iphone from carephone warehouse, sim free and with no contract. 5 months down the line I had a problem with the phone and I booked a genius appointment, they swapped my phone and gave me a new phone but they locked my phone to tmobile!!! I now do not use tmobile and I have an iphone which is locked to tmobile!!! I bought an unlocked phone and apple have locked it!!! what can i do?

In response to this, Carphone Warehouse (and Phones4U) sell what is commonly referred to as "sim free" handsets - these are not the same as unlocked. Sim free handsets will automatically lock to the first network sim card that the phone is activated with, and that will be permanently. The only way to unlock the handset would be to go through the network (T-Mobile I understand) and request they unlock it for you. More than likely, there will be a charge as you are no longer a T-Mobile customer.
If you ever want to purchase a new unlocked iPhone, the only place you can buy one is from Apple directly. Any other place will most likely sell sim free handsets.

Are you using the latest version of Silverkeeper? - v.2.0.2 is stated to be compatible with Snow Leopard.

If it's messing things up you could try asking LaCie Support for assistance.

I am using iPhoto 11 and my library has 736.5mb on disk. I have problems with iPhoto stalling and needing to force quit. I have rebuilt my library. Can you suggest anything else?

I am using iPhoto 11 and my library has 736.5mb on disk. I have problems with iPhoto stalling and needing to force quit. I have rebuilt my library. Can you suggest anything else? Thanks, Rose

Make a temporary, backup copy (if you don't already have a backup copy) of the library and try the following:
1 - delete the iPhoto preference file, com.apple.iPhoto.plist, that resides in your
User/Home()/Library/ Preferences folder.
2 - delete iPhoto's cache file, Cache.db, that is located in your
User/Home()/Library/Caches/com.apple.iPhoto folder.
Click to view full size
3 - launch iPhoto and try again.
NOTE: If you're moved your library from its default location in your Home/Pictures folder you will have to point iPhoto to its new location when you next open iPhoto by holding down the Option key when launching iPhoto. You'll also have to reset the iPhoto's various preferences.
NOTE 2: In Lion and Mountain Lion the Library folder is now invisible. To make it permanently visible enter the following in the Terminal application window: chflags nohidden ~/Library and hit the Enter button - 10.7: Un-hide the User Library folder.
If that does'nt help log into another user account on your Mac and try iPhoto from there.
