Problem accessing child object and changing its appearance (color)

For a program, I need to be able to access a child object (in this case a box) after adding it to a transform group and change its appearance, for example the color of its top face. I have included a small code example to show my problem. The box is the only child I have added to the TransformGroup, but when I call getChild(), it returns a node, and thus I can't then call getShape() to get the top face and change its appearance. What am I doing wrong?
public BranchGroup createSceneGraph() {
     BranchGroup objRoot = new BranchGroup();
     Transform3D rotate = new Transform3D();
     Transform3D tempRotate = new Transform3D();
rotate.rotX(Math.PI/4.0d);
     tempRotate.rotY(Math.PI/4.0d);
rotate.mul(tempRotate);
     TransformGroup objRotate = new TransformGroup(rotate);
     objRoot.addChild(objRotate);
     Appearance ap = new Appearance();
     Appearance app = new Appearance();
     Appearance apr = new Appearance();
     ColoringAttributes colr = new ColoringAttributes();
     ColoringAttributes colg = new ColoringAttributes();
     colr.setColor((float)1, (float)0, (float)0);
     ap.setColoringAttributes(colr);
colg.setColor((float)0,(float)1, 0);
     apr.setColoringAttributes(colg);
     Box box = new Box((float)0.4, (float)0.4, (float)0.4, app);
     box.getShape(4).setAppearance(ap);
     objRotate.addChild(box);
     objRotate.getChild(0).getShape(4).setAppearance(ap);
objRoot.compile();
     return objRoot;
}

It would help if you gave us the following System information:
Operating System/version
Photoshop version number
Amount of RAM installed
Hard drive(s) capacity
Make and model number of video card
Also try resetting your preferences as described in the FAQ.

You either have to physically delete (or rename) the preference files or, if using the Alt, Ctrl, and Shift method, be sure that you get a confirmation dialog.
This resets all settings in Photoshop to factory defaults.
A complete uninstall/re-install will not affect the preferences and a corrupt file there may be causing the problem.

Problem accessing an object in a VBox

Hi!
I have a problem accessing an object which is in a VBox.
I made an example so you can see my problem. I am trying to
access pnlChat.
If you load the swf you won't see the Alert because there is
something wrong (and I don't know what)
If you try to remove the <mx:VBox> tags that wrap the
pnlChat Panel, it will work.
Why can't I access this object when it is in a VBox?
Thanks

From the FAQ I'm compiling:
Q: I need to set a property or add an event listener on a
component
that is in a ViewStack/TabNavigator/Accordion. When the
component is not
the first child of the Navigator Container, I get a null
object error
(#1009). What causes this, and how can I fix it?
A: By default, the Navigator containers only create the
children of
each pane as that pane is viewed. The easy way to fix this is
to set the
creationPolicy on the Navigator to "all." However, this will
cause your
application to take longer to load. A better way to fix this
is to wait for
a later event, such as creationComplete on the component you
want to access,
or to use binding to "pull" the data into the component.
The way I handle it is to call invalidateProperties() on
change of the
ViewStack. I then override commitProperties() and call an
"initializer" for
each pane. In the body of each initializer function, I check
to see if the
selectedItem for the viewStack is the one my initalizer cares
about. If
not, I return from the function immediately. Inside that
initializer
function, I set properties and add listeners as appropriate.

How to check if a user has clicked on a digital control and changed its value?

Greetings !!!
I am looking for a simple way (without using Windows messages)of knowing if an user has clicked on a digital control and changed its value.
I have tried the key focus property; but I have to click twice to make it work.
If somebody knows a better solution; please let me know.
Thank you in advance for your help

If you just want to know if the value has changed you can put it in a while loop and use shift registers to see if the value has changed.

Ugent help - Every time i go to a secure website firefox latest version says This Connection is Untrusted. This was never there before and now its appearing

Every time i go to a secure website using firefox latest version i get an error saying "This Connection is Untrusted" This was never there before and now its appearing. My computer clock and date is correct and i have tested out all plugins that they are updated. Also did a scan on all viruses and spyware nothing there any help please.

Sorry, I didn't look at all the images.
You can see that the certificate is issued by your security software (Firewall): ESET SSL Filter CA<br />
So you will have to disable that filter or install the ESET root certificate that chains to that certificate.

Can you update an iOs app and change its platform offering from iPad/iPhone to just iPad?

When building a new app with Adobe DPS to update an existing app, can you update an iOs app and change its platform offering from iPad/iPhone to just iPad?

Vinod is correct in that you can build a new app that's iPad-only, but if you try to submit it as an update to the existing app, Neil is correct--Apple will reject it because it's considered a downgrade. You either need to stick to the universal app and do something like create a single iPhone folio that refers users to the iPad, or you need to submit it as a new app.

Problem with child objects created in custom tree data descriptor

I have a set of AS objects that must be represented in a
tree. Some of them are branches with various numbers of children
while some are leaves. The branches can have additional branch or
leaf children. One type of node in particular, let's call them
Elephant objects, is causing me grief. Elephants contain one array
of Chicken objects and a second array of Monkey objects. I must
represent the set of Chickens and Monkeys as sub-folders of their
parent Elephant object rather than listing all of the Chickens and
Monkeys as individual children of the Elephant. I have been trying
to solve this problem by creating new children objects on the fly
from within the getChildren function of an ITreeDataDescriptor
implementer class, which I've attached to this message.
The problem I encountered is that the Chicken and Monkey
branch/folder objects that I create on the fly and add to the tree
will not open, though they appear in the tree as expected. Is
creating objects and adding them to a tree in the getChildren
function bad? I hope there's something obvious that I'm doing
wrong.

Problem with Retrieving objects and using info...

Ok heres my problem.
I have implemented a Queue using a linkedlist in java. Ok then i created a new object(in its own class - called Data) with two values, amount and price. I want the queue to store these two values in one Node. So i pass the values to it like this:
Data A = new Data();
A.price = Intger.parseInt(jTextField.getText());
A.amount = Integer.ParseInt(jTextField.getText());
Now I pass the Queue like this
Queue B = new Queue ();
B.enqueue(A);
Which seems to work fine, the problem is that I need to work with the numbers in the Queue, update them, put them back and retrieve them.
So I create a new Data object and try to dequeue like this:
Data C = new Data();
C = B.dequeue(); //So i can work with the two values
but this doest work. It gives me the error that it needs an object.
Am I doing it right?
Anyone got any better ideas on how to do this? - Passing and retrieving two values to one Node.
Plz help, im a newbie in Java, and cant find any tutorials on the internet.

why don't you use vector.
Vector queue = new Vector();
Data a = new Data();
a.price = Intger.parseInt(jTextField.getText());
a.amount = Integer.ParseInt(jTextField.getText());
queue.addElement(a);
Data c = new Data();
c.price = Intger.parseInt(jTextField.getText());
c.amount = Integer.ParseInt(jTextField.getText());
queue.addElement(c);

Delete only the child object and not the parent object

Hi,
I have the below code:-
TAnswer
@ManyToOne(fetch = FetchType.LAZY)
     @JoinColumn(name = "question_id", nullable = false)
//     @Cascade(value=CascadeType.ALL)
     public TQuestion getTQuestion() {
          return this.TQuestion;
     }     TQuestion
@OneToMany(fetch = FetchType.LAZY, mappedBy = "TQuestion", orphanRemoval = true)
     @Cascade(value=CascadeType.ALL)
     /*@Cascade({org.hibernate.annotations.CascadeType.SAVE_UPDATE,
            org.hibernate.annotations.CascadeType.DELETE,
            org.hibernate.annotations.CascadeType.MERGE,
            org.hibernate.annotations.CascadeType.PERSIST,
            org.hibernate.annotations.CascadeType.DELETE_ORPHAN})*/
     public List<TAnswer> getTAnswers() {
          return this.TAnswers;
               In Java:-
     public void removeAnswers(TQuestion question)
                    throws ApplicationException {
               List<TAnswer> answerList = question.getTAnswers();
               deleteall(answerList);
     public void deleteall(Collection objects) {
               try {
                    getHibernateTemplate().deleteAll(objects);
                    getHibernateTemplate().flush();
               } catch (Exception e) {
                    throw new ServerSystemException(ErrorConstants.DATA_LAYER_ERR, e);
     }               Here the "deleteall" will delete both the answer records and question records, I don't want the questions
     records to be deleted. I have tried making the question as null when we set the answer object to be passed for delete
     bit still it is     deleting the question records as well.How to achieve the above in deleting only the answer (child) records
     and not the question(parent) record? Is there any thing we need to do with @Cascade for Question object? Please clarify.
Thanks.

What does deleteAll do, it doesn't look like a JPA method. You might want to ask your question on your provider forum, or use straight JPA methods as a simple EntityManager.remove(answer) on each answer in the collection should work.

Chris

Problem accessing Facebook (Safari and Chrome w/ 2 different Macs)

For over a week im having problems accessing facebook and netflix, the timeline does not seem to load properly and some links dont work, im having the same issue using the latest version of chrome and safari. im using two different macbook pros, and both have the same issue, a windows computer in the same network doesnt have those issues. my router is a apple extreme.

Someone here with a similar problem seems to have fixed it by adding some DNS settings:
https://discussions.apple.com/message/15783303#15783303
To do it:
System Preferences>Network, click on your WiFi connection on the left then click on the Advanced button, select the DNS tab. Under the panel DNS servers click on the '+' sign and insert the numbers 208.67.220.220 - click the '+' again and insert 208.67.222.222
Alternatively to the numbers listed you can use 8.8.8.8 and 8.8.4.4
Save the settings - hopefully it'll make a difference.

Problems Moving An Object Perpendicular To Its Perspective Grid

I have been following this tutorial: http://tv.adobe.com/watch/learn-illustrator-cs5/mapping-flat-artwork-to-the-perspective-gr id/ in which artwork is mapped to the perspective grid.
Towards the end of the video (7:00) a sign is mapped to the left grid then moved perpendicular along the right grid ... this is achieved by holding down the tilde key.
When I hold down the tilde key and move the object (which is selected with the perspective selection tool, with the correct grid selected ) it does not map it perpendicular as in the video.
I have deleted my illustrator preferences file (in case any settings were causing this feature not to work). Also if I create a new object and press the tilde key and drag I can create multiple instances, so the tilde key at least in this case is being recognized.

Problem with childs nodes and automatic key mapping in a Data Object

Hi experts!
I'm doing the service order tutorial from the mobile help at [this link|http://help.sap.com/saphelp_nwmobile71/helpdata/en/21/9b5b924c3b434fba4767731794b029/frameset.htm] and I have a problem...
In the topic "Modeling the Equipment Data Object", says you have to mark the "Automatic Key Mapping" checkbox. So when I had to create a third child node ( the location node ) the system raised an exception with the message "Deselect automatic key mapping flag for more than two-level nodes". I'm trying deselecting the flag and creating the location node, but when I want mark again the automatic key mapping flag, this is disabled.
What can I do to solve this and create the three child nodes with the flag marked? It's a configuration thing?
Any help it's very welcome. Thanks in advance.
Best regards,
Simon.

The thing is: Its not allowed to use automatic keymapping if you have more than two levels. This is why the message showed up, and this is why its been disabled.
What automatic keymapping does: Figures out automatically which child node belongs to which parent (by guessing from the field name and type, which fields in the child correspond to which key fields of the parent).
On three levels, this becomes more complicated => Its disabled.
How to do keymapping yourself instead of having the DOE do it automatically: Do 'Explicit keymapping' from each child to its parent. Explicit keymapping is done by clicking on the corresponding menu button in the child node. Here you need to associate child node fields (they need not be key fields of the child, but they are allowed to be that as well) to each of its parent nodes key fields (so that each child can be associated to its parent).
Cheers

Could not ping and access a server after changing its ip

I could not ping and access a (destination) machine from another (source) machine after changing destination machine ip although I modified hosts file and hosts map in the source machine
I can access the destionation using IP. This problem happened in case of using hostname not IP

I've change from "server" to "machine" to avoid misunderstand

Update for this situation
omcsp4
IP: 192.6.6.40
omcsp8
old IP: 192.6.6.180
new IP: 10.57.217.80
When I ping from omcsp4 to omcsp8, there's no answer and the hostname is resolved as *192.6.6.180* which is the old IP. But in hosts file, the IP is the new one.
omcsp4:omcadmin > ping -a omcsp8
no answer from omcsp8(192.6.6.180)
omcsp4:omcadmin > grep omcsp8 /etc/hosts
10.57.217.80 omcsp8
omcsp4:omcadmin > ypcat hosts | grep omcsp8
10.57.217.80 omcsp8
omcsp4:omcadmin > ping 10.57.217.80
10.57.217.80 is alive
These above operations show that the hosts file and NIS are both updated with the new IP address of omcsp8. But when i ping omcsp8 (by name) it returns the old IP address. So the question is from where the system omcsp4 resolve the hostname omcsp8???

Why is the dock so ugly and can I change its appearance?

Can I change the look of the dock in mountain lion?

You can hide the Dock by going to System Preferences/Dock; choose Automaticlly Hide and Show the Dock, and it will disappear until you want to see it. This is especially useful if you use a portable Mac.
However, if you want a full makeover, try this:
http://osxdaily.com/2012/01/13/change-customize-the-dock-in-mac-os-x-lion-with-d ocker/
CandyBar http://candybar.en.softonic.com/mac is almost as flashy and attractive.
