DataGrid does not update when you use the tabs

I have a panel with a TabNavigator with two legs (VBoxes). Each VBox contains a DataGrid control. I update the dataprovider of two DataGrids using a table for each in ActionScript, but only the data of the selected tab (default index 0) grid is updated, and the second tab DataGrid generates an error (TypeError: Error #1009: cannot access a property or method of a null object reference) and is not up-to-date. Any help would be appreciated. Code attached.

Set the creationPolicy = "all" because the children of the other tab cannot exist until they are displayed initially.

creationPolicy = "all" might affect performance, and if so, you can initialize the other children of the tab, perhaps in the events to initialize or creationComplete TabNavigator.

    SpeedGrade CC14 does not open when you use the "Direct Link to Adobe SpeedGrade... "of PremierePro CC14.

    I can open the SG of start menu/desktop computer and I can open the PP project in SG very well. The PP project contains 3 deadlines and I take one I want without any problem. Returning to the SG PP works fine as well. It seems only thing doesn't work does not automatically open the PP file and selecting the correct timeline in the Official Journal of the project.

    I had a glance at the "C:\Users\john Bishop images\AppData\Roaming\Adobe\SpeedGrade\8.0\logs\SpeedGrade.log ' but it is not updated when I try to use the link Direct from PP. command It updated when I invoke the start menu/desktop computer SG. Note that none of the other newspaper, the files are updated either (Plugin Loading.log, Database.txt Trace and Debug Database.txt). All these get updated when I run the desktop/start. It would appear that SG is not yet known.

    I uninstalled the SG and the PP and re-installed (all in the directories by default) and everything seemed to go OK but no change.

    I also added 2 political profile the NVIDIA Control Panel, just display a message when loading SpeedGrade.exe and another for a slightly different message when loading SpeedGradeCmd.exe. SG invoking the desktop/start causes the SpeedGrade.exe message to display. Using the 'Direct link' PP file option does not display anything, reinforcing my thought that SG is just never called from PP.

  • Adobe lightroom does not update when I use the application manager to download upgrades.

    Hello

    I have problems with adobe lightroom.  It is not updated when I use the application manager to download the new updates.  I tried to uninstall the application and re-download it, however the application manager will not allow that to happen because it shows that it is already installed and up to date. I think that the problem may have started when I installed lightroom using a link which you offered when creative cloud first started offering of lightroom.  This version of the program does not appear to work with the application manager.  Please let me know what I should do to fix the problem.

  • It does not work when you use the trigger to check the data of the other table.

    Please help me with this, I put a trigger on a table, but it can not work as I expect.

    case study: a class has many students, one of them is going to match.
    The purpose of this trigger is to check when to choose a student going to match, this student has in his class where it belongs to.
    Oracle version is 10.2.0.1.0.

                        );
    end;
    /
    

    DBMS_OUTPUT creates only a message. The message may not be displayed, and if this is the case, then the user cannot see it. The DML will still take place.
    I used instead, RAISE_APPLICATION_ERROR to keep the DML does not happen. It displays a message like

    ORA-20000: Please re-enter class id and student id as class (1) or student (3) is not valid.

    I think that now you're saying that the new values of (class.cid, class.schosen) must be equal to (or "fit") some existing (stu.cid, stu.sid).

    3. thanks for your tip, I learned how to use '{code} '.

    4. it's really goes with the exception of MUTATING_TABLE. So, how do to fix the trigger to show me INVALID_STU EXCEPTION when I try to choose a student does not belong
    a class?

    Don't refer to the table of class in the trigger, and the error table mutation occur. All the information you need are in the stu table, so there is no need to query the table of class, anyway.

  • Portege M200: registering does not voice when you use the handwriting recognition

    When I'm in "tablet mode" using handwriting text recognition that my Portege M200 regularly presents a message to say, he could not save the speech recognition and I have to switch off the microphone if I do not use it. I often use it to take notes of the meeting so there is always background noise. Usually, text is lost when this message appears. The message will also appear when I save.

    How to turn off the microphone while maintaining the functional handwriting recognition please?

    Just a question: what software do you use for text recognition?

    I think that your case is equivalent to "loading lazy trees."  There are examples
