NullPointerException in screen #navigationMovement Manager

Hello

After you add a VerticalFieldManager to a screen, Manager of navigationMovement super screen throws a NullPointerException and the verticalFieldManager scroll with the trackpad of this point (using the Enter key to scroll works very well and after once the trackpad works again scroll).

I use the same model as this post defining NullField focus on the top and the bottom of the field with vertical scrolling. Has anyone have the same problems, or have any ideas on places of interest to search for?

I'm sorry, that I couldn't reproduce it with a simple example. After a few hours, I was able to solve the problem by changing the hierarchy of my screen area, adding a handler of accepting high-field the developed anything in it.

I think what he throwed NullPointerException because he could not find a field of focus when took place the first movement of the navigation, or the system has attempted to lock the focus on an element unfocusable. I have no final conclusion, I could work around it by rearranging the fields.

    I get a blue screen error memory management and he uses all ram memory cache and it has 0 MB of free space please help

    Hello zinco524,

    This looks like a bad memory or not enough on your system.  You should test the RAM on your system:

    Memory diagnostic tool

    1. Diagnostic tool memory open by clicking the start (Orb)> click on Control Panel > system and Maintenance > click Administrative Tools > and then click on diagnostic memory tool. If you are prompted for an administrator password or a confirmation, type the password or provide confirmation.
    2. The choice between two options for the time of execution of the memory diagnostic tool:
    1. You can restart your computer and run the tool immediately.
    2. You can restart your computer and run the tool later.

      This will help during an attempt to avoid a possible hardware problem. Hope this helps you. Make it a great day!

  • Unable to load the splash screen Startup Manager (by pressing F12 either does nothing or freezes the screen)

    Search on Google for a few days now, seems to be a rare problem I have found only ONE thread referring to a problem like this

    Problem:
    Boot Manager does not load
    Case 1: Start (with Toshiba logo) screen-> I press F12 for the Boot Manager. Nothing happens, and initialize routinely at the login screen, as if nothing had happened.
    Case 2: Splash screen-> in the crazy frustration I spam the button F12. The computer remains frozen in the home screen for hours otherwise force-closing
    Case 3: (this can be linked) by pressing the button F3/F8 works, but only if I wait 5 seconds. If I press immediately after starting the computer, the screen freezes again and remains frozen. In addition, it will NOT display the live cd USB drives / bootable, that I plugged in; o

    Details:
    I have Vista Home Edition 32-bit
    I've never reinstalled it, and I want to keep avoiding a complete reinstall if it isn't necessary because most of the problems can be resolved without having to reinstall and it's a pain in the _ to save everything, save parameter files and all that.
    A virus that could cause this would probably be beyond the capabilities of Avast, but always I ran a scan with Avast antivirus full (and own)

    If anyone has any suggestions please email me at vrielis@gmail (no matter how old this post is!) I'm getting desperate. o I also check here regularly, but I would prefer email

    Hello

    Reinstall would be a waste of time because, as I already pointed out, the problem is not in the operating system. It has everything to do with how Toshiba implements access to their volume of recovery and absolutely nothing to do with the operating system. Your best chance of resolution is the manufacturer. If you take this route or not is your choice. Good luck, Rick Rogers, aka "Crazy" - Microsoft MVP http://mvp.support.microsoft.com Windows help - www.rickrogers.org

    See the code highlighted in red? That's your problem. I bet your IllegalStateException said something on a field "already apparent. Do not add your manager on the screen at all - defining it as banner adds to the hidden screen banner Manager. So remove the code highlighted, and you should be fine.

  • Portege M750 with Windows 7 - Screen Rotation button not working not properly

    I installed new Windows 7 on a Portégé M750 and everything seems fine except the buttons on the screen to manage the features of the tablet. The only thing I really want to work is the orientation of the screen one. I looked for drivers, but can't find anything in order to control the tablet buttons. I read that for the M700 you need to download the driver for the Tablet because it contains the drivers for the buttons, but there is no driver for the M750.

    All devices are ok in Device Manager with no need of drivers.

    Any thoughts/ideas/suggestions are welcome.

    Hello

    The Toshiba Euroepan driver page offers two different packages with added value.
    It is version 1.2.40 and the other is the 1.2.28_64 version - 2
    Check both!

    Also, I searched published for other series of protected M780 and pilots found Package of Extension Tablet Win 7 32 bits and added value Package v 1.2.34

  • 'New window' does work well across multiple screens

    OS X 10.11.3 (15 D 21)

    I have two monitors connected to my rMBP with Thunderbolt ports.

    To facilitate the description, I want hereby the two views under A and b.

    Assuming an application (for example, chrome, finder) window was launched in A display. So I want to open another window display B. I right click the icon in the Dock on display B and click on 'new window '.

    What I expected, it's a new window opens in view B because I clicked on 'new window' display B, but the reality is a new window always opens in display has.

    On the other side, the same operation between different spaces (desktops) has no such situation. New windows are open correctly in places where they are "printing".

    Is there a bug in 'new window' between multiple screens?

    Hello is.

    I understand that you are wanting to open new windows of applications on the screen that you are working on. It is perhaps because of the way in which several screens are managed. Revisit some information to get this working for you.

    When you open a new window of an application, it will open in the active view. Even if you have the dock on the other screen, look at your taskbar to see if it is translucent. If this is the case, then it is not your main screen and your applications will be opened on the main screen. See the image below for what I will speak about reference.

    Take a look at the article below for more information on the use of several screens. I know the article refers to the Mavericks, but the information extends to OS X El Capitan as features are concerned.

  • Satellite A20 - screen begins to turn white

    Any help will be useful, thank you advance.

    Hi IBE876,
    What a Pseudo ;-)
    It looks like problems with the lcd screen.
    to me it looks loke a defective cable and / or a bad inverter.
    do not open the cover of the display until you know what you're doing and you have no guarantee on this machine more...
    This inverter is a dangerous thing! It produces a high for the lighttube voltage.
    If it is still warranty on this unit, better consult a servicepartner, there also the spareparts right...
    If you want to do it by yourself... Keep in mind, it can be dangerous!
    Make sure no powersource is connected to your system and battery is taken out.
    Maybe it could be a loose cable...

  • Vista black screen after the loading bar

    I have the problem that I am assuming that almost all users of Windows Vista have probably experiences - the black screen with the white cursor lonely after the loading bar 'Microsoft Corporation'. Here are the steps that I tried to solve the problem, but have not yet worked:

    • With the help of "last known good configuration" brings back me to the screen and the white slider
    • Go into safe mode which brings back me to the screen and the cursor
    • Activate the video mode low resolution which brings back me to the black screen and a cursor
    • Using Ctrl + SHIFT + ESC to appear during the black screen Task Manager
    • CTRL + Alt + Delete does not work on the black screen
    • I do not have access to the installation CD, as it was preinstalled on the computer

    Yes, as usual, what happened after a windows update - I really should stop waiting for something good to these updates.

    I'm under the original version of Vista Home Premium without service pack - these caused a similar problem, but at least I was able to return the system restore.

    Thank you in advance, I know how useful these forums can be.

    Yes, a new installation of Windows 7 was the way for me. Lucky he composed a back all my documents, however. Thanks for the help all. Unfortunately I have no where near more closely to solve the problem, then when I started.
