Trackpad not working as expected

Hi
I bought a new 27" iMac with a trackpad about three weeks ago and ever since I ve been having problems with the trackpad
If I go to click, for example , on a menu item in an app or in safari on a link, every so often the cursor disappears and appears by the trash can, it all happens in a split second, at exactly the time I click. Sometimes the cursor ends up opening a minimized item from another app or another page before i know what is going on
I have checked the bluetooth settings, downloaded xcode as someone suggested, and used the Bluetooth Explorer, rang Apple five times and spoke to various Apple Experts, reset the PRAM, taken the batteries out, unpaired the trackpad and keyboard, deleted the plists in the preferences in the libraries and probably a few other tasks that I have forgotten .
I have reduced the gestures in the system preferences hoping that might have an effect , it didn't
Also Apple sent me another trackpad out to try but the same problem occurs
I must admit i am getting used to it slighty but my wife and daughter have not been on the new imac yet and i fear there could be many tantrums when they do begin
Anybody got any ideas as Apple are ringing me again tomorrow about 4.30pm BST for another attempt
Thanks

I thought if I could get some software that identifies any other bluetooth devices and their signals etc it might help me to sort out this spcific problem
So does anyone know of any suitable software
Bluetooth Explorer. It's part of the apple xcode developer tool set so you need to install xcode.
When you launch BT Explorer there's a number of tools and displays in it. Probably the best in your case is the Connection Quality Monitor. Here's an example:
The plot in the upper left shows basically the signal strength of each device paired with your system.
Update: The thing is here if there are other BT signals "floating around" the above won't show it. It's only monitoring devices it knows about (i.e., paired). But interferance may be a problem, say from wireless devices. See the following:

Macbook pro Late 2011 13.3 inch i7 keyboard and trackpad not working bluetooth showing a cross sign and no usb mouse is detected. Almost dead keyboard and mouse. Earlier same problem used to be solved by opening the lower cover and closing it.

My macbook pro 13.3 inch i7 late 2011 edition has previously encountered unresponsive trackpad and keyboard. To solve that, I used to open the back cover and then close it. It has been working fine since that. Yesterday, same thing happened, this time I noticed that bluetooth icon is showing a cross sign across it and keyboard and trackpad were unesponsive. After some time , everything worked fine and bluetooth sign was back to normal. Then , suddenly it went back to the problem. I shut it down by holding the power button. When I booted it again, I could not login because keyboard and trackpad were not working. I attached a HP mouse it didnt work. I opened the back cover disconnected the battery and then connected it again, didnt worked. Since then , I have tried many things and nothing has solved the problem.

@sanjampet
As you suggested I reset the smc, in the first boot nothing worked. In the second boot, it all worked like a charm. I thought that my problem is resolved now. To test it, I shut it down properly. Next morning, I powered it on, all things i.e, keyboard, trackpad, bluetooth etc. worked and I thought that problem has been solved. When I was just going to visit apple forum to reply you, the same problem reappeared. A sawtooth cross over bluetooth icon, keyboard not working, trackpad not working,no usb mouse working which worked well when it was fine. I reset smc so many times again and again but same problem continued. Isn't it a problem of the firmware?
Next time when it will work, I will update its firmware.
My macbook was bought in dec2011 so no warranty now.

Silverlight 5 binding on a property with logic in its setter does not work as expected when debug is attached

My problem is pretty easy to reproduce.
I created a project from scratch with a view model.
As you can see in the setter of "Age" property I have a simple logic.
public class MainViewModel : INotifyPropertyChanged
public event PropertyChangedEventHandler PropertyChanged;
private int age;
public int Age
get
return age;
set
/*Age has to be over 18* - a simple condition in the setter*/
age = value;
if(age <= 18)
age = 18;
OnPropertyChanged("Age");
public MainViewModel(int age)
this.Age = age;
private void OnPropertyChanged(string propertyName)
if (this.PropertyChanged != null)
PropertyChanged(this, new PropertyChangedEventArgs(propertyName));
In the MainPage.xaml
<Grid x:Name="LayoutRoot" Background="White">
<TextBox
Text="{Binding Path=Age, Mode=TwoWay}"
HorizontalAlignment="Left"
Width="100"
Height="25"/>
<TextBlock
Text="{Binding Path=Age, Mode=OneWay}"
HorizontalAlignment="Right"
Width="100"
Height="25"/>
</Grid>
And MainPage.xaml.cs I simply instantiate the view model and set it as a DataContext.
public partial class MainPage : UserControl
private MainViewModel mvm;
public MainPage()
InitializeComponent();
mvm = new MainViewModel(20);
this.DataContext = mvm;
I expect that this code will limit set the Age to 18 if the value entered in the TextBox is lower than 18.
Scenario: Insert into TextBox the value "5" and press tab (for the binding the take effect, TextBox needs to lose the focus)
Case 1: Debugger is attached =>
TextBox value will be "5" and TextBlock value will be "18" as expected. - WRONG
Case 2: Debugger is NOT attached =>
TextBox value will be "18" and TextBlock value will be "18" - CORRECT
It seems that when debugger is attached the binding does not work as expected on the object that triggered the update of the property value. This happens only if the property to which we are binding has some logic into the setter or getter.
Has something changed in SL5 and logic in setters is not allowed anymore?
Configuration:
VisualStudio 2010 SP1
SL 5 Tools 5.1.30214.0
SL5 sdk 5.0.61118.0
IE 10
Thanks!

Inputting the value and changing it straight away is relatively rare.
Very few people are now using Silverlight because it's kind of deprecated...
This is why nobody has reported this.
I certainly never noticed this problem and I have a number of live Silverlight systems out there.
Some of which are huge.
If you want a "fix":
private void OnPropertyChanged(string propertyName)
if (this.PropertyChanged != null)
//PropertyChanged(this, new PropertyChangedEventArgs(propertyName));
Storyboard sb = new Storyboard();
sb.Duration = new Duration(new TimeSpan(0, 0, 0, 0, 100));
sb.Completed += delegate
PropertyChanged(this, new PropertyChangedEventArgs(propertyName));
sb.Begin();
The fact this works is interesting because (I think ) it means the textbox can't be updated at the point the propertychanged is raised.

Subtraction of two key figures normalized to result not working as expected

Hello SAP Community!
I am having problems with getting the right result from a subtraction of two KFs which are "normalized to results" which means the KFs really have values expressed as percentages. The substraction that should be performed is of two percentages (e.g.: 87.298% - 85.527% = 1.77%) but my report prints out the result as "number of units" instead (e.g.: 87.298% - 85.527% = 71,514.00 EA). The two normalized KFs actually "point" to two stock KFs, hence the "number of units".
In order to explain the problem I am facing please analyze below text:
1) Let's assume I have below data:
LOAD MONTH PLANT    MATERIAL HORIZON MONTH     FORECAST UNITS
200805         PLANT-A MAT-1            200805         510,235.00
200805         PLANT-B MAT-1           200805          74,240.00
200805         PLANT-A MAT-1           200806         438,721.00
200805         PLANT-B MAT-1           200806          74,240.00
200805         PLANT-A MAT-1           200807         356,981.00
200805         PLANT-B MAT-1           200807          74,240.00
200806         PLANT-A MAT-1           200805               0.00
200806         PLANT-B MAT-1           200805               0.00
200806         PLANT-A MAT-1           200806         510,235.00
200806         PLANT-B MAT-1           200806          74,240.00
200806         PLANT-A MAT-1           200807         438,721.00
200806         PLANT-B MAT-1           200807          74,240.00
2) Then, assume I have a comparison report, restricted by load month for two months May and June 2008 (filter restricted by two month variables) with FORECAST units spread accross columns for whole horizon (two months also in this case).
Material Plant                                 2008/06     2008/07

                   Comparison Units (June 2008) 510,235.00 438,721.00
          PLANT-B
                   Base Units (May 2008)         74,240.00   74,240.00

                   Comparison Units             584,475.00 512,961.00
3) Now, let's suppose we want to know the proportions (%) of Base vs Comparison units, so
we normalize forecats to results an we get the below report:
Material Plant                                 2008/06     2008/07
===================================================================

                   Base Units % (May 2008)      85.527%     85.527%
                   Comparison Units (June 2008) 510,235.00 438,721.00
                   Comparison Units %(Jun 2008) 87.298%     82.784%
          PLANT-B
                   Base Units (May 2008)         74,240.00   74,240.00
                   Base Units % (May 2008)       14.473%     15.702%
                   Comparison Units (June 2008) 74,240.00   74,240.00
                   Comparison Units %(Jun 2008) 12.702%     17.216%
          TOTALS   Base Units                   512,961.00 431,221.00
                   Comparison Units             584,475.00 512,961.00
4) Finally, let's suppose we want to know the deltas (differences) of Base vs Comparison
units, for both number of units and %. The report now look as below:
Material Plant                                 2008/06     2008/07

                   Base Units % (May 2008)      85.527%     85.527%
                   Comparison Units (June 2008) 510,235.00 438,721.00

                   Base Units (May 2008)         74,240.00   74,240.00
                   Base Units % (May 2008)       14.473%     15.702%
                   Comparison Units (June 2008) 74,240.00   74,240.00
                   Comparison Units %(Jun 2008) 12.702%     17.216%
                   Delta base vs. comp. units % -1.77%      -2.74%
                   Delta base vs. comp. units         0.00        0.00
          TOTALS   Base Units                   512,961.00 431,221.00
                   Comparison Units             584,475.00 512,961.00
5) PROBLEM:
In my report, the "Delta base vs. comp. units %" is not working as expected and
calculates number of units just as "Delta base vs. comp. units" does instead of calculating the % difference.
So my report looks as follows:
Material Plant                                 2008/06     2008/07

                   Comparison Units             584,475.00 512,961.00
The formulas are:
a) Delta base vs. comp. units %
Delta base vs. comp. units % = Comparison Units % - Base Units %
b) Delta base vs. comp. units
Delta base vs. comp. units = Comparison Units - Base Units
The KFs
- Comparison Units %
- Base Units %
Are RESTRICTED key figures (restricted to Base and comparison month variables) which
are setup as:
1) Calculate Result As: Summation of Rounded Values
2) Calculate Single Value as: Normalization of result
3) Calculate Along the Rows
The KFs
- Delta base vs. comp. units %
- Delta base vs. comp. units
are FORMULAS setup to:
1) Calculate Result As: Nothing defined
2) Calculate Single Value as: Nothing defined
3) Calculate Along the Rows: user default direction (grayed out)
Thanks for the time taken to read in detail all of this. Long text but necessary to understand what the problem is.
Any help is highly appreciated.
Thank you.
Mario

Hi,
The subraction will be carried out before doing the normalization of your KF's. So, it is displaying "number of units". Create a calculated keyfigure and subtract the KF's and in the properties of this calculated keyfigure, change the enhancement as "After Aggregation".
I hope this will solve your issue.

Events in SubVi not working as expected

Hi, I am reposting this question as my previous one didn't resulted in any satisfactory conclusion.
I have attached my Vi's which are not working as expected. If I remove ONE subVi and its associated 3 controls and two indicators, the other one works just fine, but when I add two SUB Vis, it goes messy. I am trying to learn this way, I am sure it can be done many other ways, but please help me finding out the problem doing it this way as in my final MainVi, I would like to use 8 such sub Vis. Thanks.
Solved!

Your main problem is DATA FLOW. A loop cannot iterate until EVERYTHING in it has completed. So, as you have it, you have to have both event structures execture before you can go back to look for the next event. So if you insist on having these subVIs, they need to be in seperate loops.
BTW, you can get away with a single subVI. Go into the VI properties and make it reentrant (preallocated clone). Then each call of your subVI will have its own memory space. A lot easier to maintain that way.
And I know you said you didn't want alternatives, but here's how you can do it all with a single event structure in your main loop.

AFS ARUN Size Substitution Not Working As Expected

Hi All,
I need help with this. If any one of you have worked with AFS ARUN size substitution, kindly provide me with some details on how can I set it up. I am specially interested in setting up size substitution with two-dimensional grids.
I have setup some examples but it does not work as expected.
Here is a small example:
Say I have a size 28/30, 28/32 .........29/30....
What I want to achieve is that during ARUN if there is a shortage of stock in 28/30 then the remaining requirement qty should be confirmed from size 28/32.
with my setup after 28/30 it goes into looking for stock in 29/30, which is what I do not want.
Any inputs will be really appreciated.
Thanks!!

Hi YOS,
I tried importing a PCX image into CVI 2010 and then sizing the image to the control and didn't see the behavior you have been describing. Would you mind posting an example (alongside an image file) that demonstrates this?
Also, one thing I noticed is that PCX images appear to be quite dated. Could upgrading them to a JPEG or PNG format be an option for you?
Thanks,

Stephanie, thanks for the reply.
I am very sorry to state that I made a mistake.
VAL_SIZE_TO_IMAGE indeed works.
What fails to work is VAL_SIZE_TO_PICTURE. (Second option in Fit Mode attribute in control editing panel)
I tried with JPEG and it's the same.
I am attaching an example.(Load_Image.c & ONEP_3Trow_POS1.JPG)
A panel with two picture rings.
- SW_1 remains at the intended size and the loaded picture is not clear.
- SW_2 will fit to picture size and looks OK.
Appreciate your support,

Notification "Launch the app and go to the library" not working as expected

Hello,
we are sending notification "Launch the app and go to the library" - but it's not working as expected, it's still just launching app with last open folio.
Whats wrong there? Do we need v30 app? We have V29, but this is not mentioned in documentation.
Thanks
Martin

Ah.
Ok, now it's clear.
Anyway i would appreciate possibility to force viewer to switch to library view after new issue is detected, even without notification. Quite often requested feature - "there is new cover in Newsstand, but customer don't know how to download new publication easily".

DB Adapter polling as singleton process is not working as expected

Am using poller DB adapater to control the transaction per seconds to the downstream system and i want this poller process as singleton (One instance should be in running state at a time).
As suggested in oracle documents , below is the parameters configured in composite.xml file.
<service name="polling_Mange_Alert_Events"
ui:wsdlLocation="polling_Mange_Alert_Events.wsdl">
<interface.wsdl interface="http://xmlns.oracle.com/pcbpel/adapter/db/Application1/int_app_manageAlerts/polling_Mange_Alert_Events#wsdl.interface(polling_Mange_Alert_Events_ptt)"/>

</service>
Below is the JCA file parameters configured :

This poller process is running on clustered environment (2 soa nodes) and it is not working as expected as singleton process.
Please advise to solve this issue ?

Hi,
1.Set Singleton property outside   <binding.jca> like this:
<binding.jca config="polling_Mange_Alert_Events_db.jca"/>
<property name="singleton">true</property>
<property name="jca.retry.count" type="xs:int" many="false" override="may">2147483647</property>
<property name="jca.retry.interval" type="xs:int" many="false"
2.Also you can try setting these values in jca file:
<property name="RowsPerPollingInterval" value="100"/>
<property name="MaxTransactionSize" value="100"/>
3. try to increase the polling interval time.

Hi,
I think window auto-tuning is enabled.
You can disable it by running the following commend.
netsh interface tcp set global autotuninglevel=disabled
Hope this helps.

Container-Managed Transaction Type Attributes not working as expected

I am having a problem with the container-managed transactions not working as expected. I have 2 methods that work as follows:
MethodA{
for(a lot)
call MethodB;
@Transaction Type = RequiresNew
MethodB{
EntityManager Persist to database
I want the code in MethodB to be committed to the database when methodB returns. The problem is that I am running out of memory and MethodA is failing. When methodA fails after numerous calls to MethodB nothing is persisted to the database.
It is my understanding that when using requires new transactions that a new transaction is started for each call to the method and ends when the method returns while the calling method transaction is suspended.
How am I misunderstanding the requiresNew transaction attribute. What can I do to make a batch insert into my database that will not run out of memory (commit when a methodB returns)?
Thanks in advance.

The problem is that EJB invocation semantics for security, container-managed transactions, etc.
only apply when an invocation is made through an EJB reference. In your case, you are directly
invoking the implementation method from within the bean. The EJB container has no idea that's
happening. It's no different than invoking a utility method.
In order to get the behavior you'd like, you need to retrieve a reference to your own bean and invoke
through that. You can use SessionContext.getBusinessObject() to get the EJB reference for the
business interface through which the method in question is exposed.

Namespaces not working as expected

Hi, I've got problems with namespaces not working as expected. When I isolate a process into a new network and mount namespace, a newly mounted file system will be visible to all processes.
Steps to reproduce:
$ sudo unshare -mn bash
bash# mount -t sysfs sysfs /sys
bash# exit
$ cat /proc/mounts
Result:
/proc/mounts will contain a new line for sysfs. This means the /sys/fs/cgroups directory will appear to be empty as the new sysfs is mounted over the old However you can undo it by
sudo umount /sys
Expected result:
The /sys directory will only be new inside the bash process started using unshare and not anymore once you exit bash.
Did I understand something wrong? Or might this be a bug in the kernel?
Note that when using
unshare -m bash
without isolating the network namespace it will refuse to mount sysfs as it is already mounted or busy. Strange.

Hello, because sysfs is shared, see unshare(1) for more details.

Wireless keyboard and trackpad not working.

iMac keyboard and trackpad not working after a couple days of not using. Hit power button on them and the light will blink, but will not function. Any help?

Have you tried a fresh set of Alkaline batteries?
Have you tried cleaning the battery contacts in them?

UpsertDocumentAsync not working as expected

I'm using UpsertDocumentAsync to either insert or update a document, but it doesn't seem to work as expected. When I use it either inserts / creates or
replaces the document. I doubt I'm calling it wrong?
await client.UpsertDocumentAsync(documentsLink, this.document);
Working as expected (but with incorrect name) or not working as expected?
Regards,

Found this one (doesn't contain the work PATCH though)

Voted for that one, but it doesn't seem like the developer community is interested in upsert/patch functionality =/.

Trackpad not working; says it's not installed

Last night, I was watching a YouTube video. Kept it open and closed my iBook G4, and today I woke to find my trackpad not working and when I go into System Prefrences, it makes no mention of a trackpad except when I type in "turn off trackpad" and it then says I don't have one installed. What's up??? I can't really open it up because it's not mine (the state gives students laptops).
It stopped working before because it got wet and I eventually dried it out and until now, it's been working fine.
Any tips? I heard it I might have to get OS X reinstalled (which is possible).

NEVERMIND!!! IT'S FIXED!!!
I somehow managed to fix it, and the trackpad is working again!!! I cleaned it real good with these "Electronic Cleaning Wipes" so maybe that's what did it (don't worry, the laptop was off and the battery was removed when I was cleaning it).
SO DON'T WORRY... IT'S WORKING!!!

TrackPad not working unless "Diagnostic Tests" app running in background

My Torch 9810 TrackPad stopped working... I had downloaded the BlackBerry 7 OS free apps including those that provide "notifications" and "text to speech" and "speech recognition" capabilities that I don't mind having to fool around with, but I don't want to use all the time... they tend to take over buttons and configuration too much, so in my efforts to remove them or at LEAST get them to stop activating every time my BB moves in my pocket I was uninstalling things. I was told I had to reboot the device, and after doing so, the trackpad would not work.
So I go back and restore my backup... and the trackpad works... briefly: all the restored apps start asking for permissions etc. and run their configuration wizards whatever and then the trackpad stopped working again.
I've tried restoring AGAIN and have even downgraded the OS to get back to a "more stable" configuration with NO third-party software installed and no luck.
At this point, the trackpad does NOT work at all in any apps. I'm sure this is a software-related problem and not that the trackpad itself is broken and needs replacement.
I've used BBSAK to try to lobotomize it back to total "factory default" but that didn't work either.
I want to rule out a hardware failure (I'm SURE this is just software related, because it happened after a reboot and there had been no problems prior to this) So today I visit the BlackBerry.com website and search for "trackpad"
I get "trackpad not working" as the first result.
"TrackPad Not Working" KB article
At the very bottom of the page is a link to the "Device Self Test Application" instructions at:
"Diagnostic Self Tests" KB Article
So as soon as I start in with the Diagnostic Self Test app, it asks "Do you want a guided setup" and shows "Yes" and "No" buttons. Instinctively I try to use the TrackPad to navigate to "No" because I just want the trackpad diagnostic, and... the trackpad works.
I exit the "Diagnostic" app and go back to my home screen and it works again... briefly...
I re-enter the diagnostic app, the trackpad works, then I long-press the Menu key to go to different apps, and the trackpad continues to work.
So, it seems like keeping the 'Diagnostic Self Test' app running in the background is 'propping up' the TrackPad so it works, but when I exit the Diagnostic app, it stops working.
Also, the back of the device seems warmer than usual, as if the CPU is being driven hard.
I'm wondering if some rogue app might be crippling the TrackPad? And the Diagnostic Self Test app is somehow pushing the rogue app aside but the rogue app is "waiting as hard as it can" and driving the CPU hard?
Yeah, I'm grasping / speculating / making stuff up, but maybe someone can decipher what I'm saying and give me some clues?
If there's a "end user totally restore the firmware to a factory configuration" that will likely resolve this issue, I'm capable enough to try it rather than be without the trackpad (or the device being repaired under warranty) for days.

Note: I decided to try exiting the Diagnostic Self Test app to see if the TrackPad would stop working... or if using a specific app made it stop working... and after doing so, then rebooting etc. the TrackPad has now been working for many hours: dare I try to reinstall some of the apps I removed?
