Content of PersistenObject disappears after you remove the app and the new facility

Hi guys,.

I discovered the following problem with my app:

1. when I update app with new version all persistent data is stored very well.

2. when I delete the app and install it again - some of the persistent data disappears, some is always there.

I think it depends on who what is persisted. If there are classes of applications store is deleted on uninstall, if there are classes of system store will not be erased.

Can you tell me about the resource, where it is described?

Thank you

Eugen

I found:

When you use the persistence model of BlackBerry, data is removed only if the store contains data that belongs to the deleted application.

For example, if an application stores an object with a package named com.mycompany.application.storage and no other application on the BlackBerry smart phone makes reference to packaging, permanent storage and the deleted application are removed.

  • Repair your startup disk Bootcamp disappearing after you create the new partition

    . After some research, I found that it was the way forward to create a separate partition, and so I did another partition.

    I didn't know it would affect my Windows partition that I thought it was completely different.

    So now, when I start it up, there is no option to start with Windows. But when I boot the Mac and select Startup disk, it displays Boot Camp is still there, and all my files etc. are still there.

    I tried to create one separate partition (other than Bootcamp). After that its done and I started my computer, I found that the option to boot Windows (Bootcamp startup disk) has disappeared. But I still see boot camp Mac files. Any solution for this? Thank you.

    (I tried to find this solution on the discussion Forum, and I found: repair Boot Camp after having created the new partition, however, I'm not able to follow these instructions. any help would be appreciated)

    You can click on the menu of your SETUP program on your screen and go to TOOLS and clean the print head from there.

  • Issue of SDRS to vCloud Director after you add the new data store to the Cluster of DTS

    Hi people,

    We use vCloud Director 5.5 in a vSphere full 5.5 environment.

    We have several DTS Cluster in vSphere and connected to vCloud Director.

    Following problem.

    When I add a data store to a Cluster of DTS and connect this to the corresponding storage profile data store, the storage profile is not available to vCloud Director more.

    After removing the new store data in the cluster of DTS, the profile becomes available again.

    Any ideas?

    Concerning

    Jean

    How did you the storage profile associated with the data store?  via c# client or vSphere web client?

    If you did the wrong way (c#) there no storage class label appropriate against it.

    A data cluster store has the storage class who would have all preparations of data contained inside.

    I think that you should check the service class is associated properly in vSphere web client (before adding to the DS Cluster).  Once it displays correctly, and then add the data store to the cluster.

  • hidden files after you remove the virus from windows recovery.

    Hello.

    I have a Sony Vaio model VGN-AR71E running Vista Home premium. He recently got infected with a fake trojan of the anti-virus/malware, which was successfully deleted.

    The virus initially seems to have erased all the etc. documents/photos/music on my laptop. Users, there is only an empty file "public". However when I search for a file by using the start menu, I can find and open a file and the location is listed as it was before the virus (for example C:/users/me/images etc.). Also when I run itunes all my music is still listed as usual and plays.

  • ValueChangeListner do not get fired when I entered the same value after you remove the first.

    Hello world

    Can anyone help on this.

    JDeveloper version 11.1.1.7

    I use '< af:inputText >' with valueCaangeListner.

    Here as soon as I entered a value, valueChangeListener get fired...

    Problem:

    When I remove the and I entered the same gain value in the text entry box, ValueChangeListner do not get fired.

    When I came again, a value different valueChangelistner get me fired.

    Kind regards

    Malenfant.

    What you say is logic and sense, you enter 500 then delete 00 then add 00 in inputText perspective there is no change in place, therefore, the converter does not occur because there is no changes occur.

    To do something like that you can do a work around using javascript. You can follow these steps:

    1. Select af:inputText and bind it to the backbean

    
    

    2 - Add clientListener and serverListener inside inputText as:

    
        
        
        
    
    

    3 - Add handelEnterButton as javascript method:

    function handelEnterButton(event)
    {
      var code=event.getKeyCode();
      if (code==13)
      {
         var source = event.getSource();
         AdfCustomEvent.queue(source,"serverListenerOperations", {}, false);
      }
    }
    

    4. in the method of serverListener back bean refresh as inputText component:

      public void serverListener(ClientEvent clientEvent)
      {
        RequestContext.getCurrentInstance().addPartialTarget(getMyInputTextComponent());
      }
    

    5. now, try to change something in the inputText and then press enter

  • Issue after you create the new partition, Bootcamp expansion

    Hello

    I hope someone can help with a problem I'm having.

    I found an old Apple discussion on how to resize a partition, bootcamp, by reducing the size of the OS X partition, then using a Windows based tool to then extend the Bootcamp partition. Big mistake! I'm done with the same problem as the creator of this thread with my Windows no longer bootable partition.

    I followed the steps described by lonely T, which worked perfectly! Thank you very much!

    Then, I went into Windows and use the Partition Mini tool to extend the Windows partition in the unallocated partition, which worked fine in Windows.

    However when I boot in OS X and open disk utility I see now 3 separate partitions. (1) mac HD. ((2) Untitled (the one I created) 3) Windows HD (Bootcamp). Then OS X is not recognizing that I extended the Windows HD partition in the Untitled one.

    Is there a way to solve this problem without ruining it now expanded Windows partition? Windows does not seem to see two separate partitions, only in OS X I downloaded GPT Fdisk

    Thanks in advance!
