The definition of dataProvider programmatically causes null reference

I am trying to bind a drop-down list box to a list of countries via a HTTPService which returns xml code. If I set the dataProvider and declaratively labelField properties in the mxml, then it works fine. However, if I try to set it programmatically in the method that is called after the called HTTPService returns, then I get "TypeError: Error #1009: cannot access a property or method of a null object reference."

Here is the dataServiceResult method:

[Bindable]
private var _lookupData:XML;

public void dataServiceResult(event:ResultEvent):void
{
_lookupData = event.result as XML;

cboCountry.dataProvider = _lookupData.countries.country;
cboCountry.labelField = "@name";
}

This causes the above error. However, if I have the last two lines of the method in comment and change the combo box return to resemble what follows, then it works fine:

< mx:ComboBox id = "cboCountry" styleName = "RequiredFieldLabel".
dataProvider = "{_lookupData.countries.country}" labelField="@name" "
change = "countrySelected ()" >
< / mx:ComboBox >

Any ideas? Declarative binding will work in this particular situation, but I have several other cases where I need binding programmatically to xml, so I need to get this script working. Thanks in advance for any help!

The simplest way around this is to link the labelField and dataProvider to a variable or a get/set accessor, and then set the variables (or the Set accessor) in the result handler.

What is happening is that the combo box has not been instantiated in the place in which you try to set the values, so the null pointer.

  • Destroy the definition component qml in c ++ destructor

    I install some components, but they can only be destroyed if the application will be closed.  Currently, a mistake is cause attesting that they are not made when the application is closed.

    Normally, you can solve it by setting the parent of all objects you create in your definition. The parent must be something that you know will be destroyed when your application is closed, as the app itself class.

    I don't think you should look for ComponentDefintion but because it's just a factory for components, you do not create. You should rather look for the type of object that creates the definition.

    Also, do you you know that some objects of Cascades don't clean up after them properly and may generate errors no 'no' even if you do everything right. Why don't post it your console error messages because it can help you get an answer better than this one.

  • Null reference close behavior

    Hello

    I have a question about the behavior of the reference 'close' when you try to close a Null reference.  LabVIEW which will examine and pass or it will produce an error?  I also read in the 'help' that you can give a table of references and it close all.  However, what happens if one of the Ref table is Null?  Is this all closes the actual Ref and continue with an error, or it does not work as a passing beam to loop around the cluster of error in the shift register thus preventing to close any other Ref?  I just want to test the code to answer my own question, but as annoying as it is the case, I'm not entirely sure if he sent a white ref is the same as sending a Null Ref.  You can answer that one as well if you wish.  Thank you.

    Looks like it will produce an error if you enter a null reference and that just sent some kind of reference constant that you did not actually open is indeed zero. If you try to close a table of references, it seems that he is trying to close between them, even if it is a null in the Middle reference.

  • Deleting the definition of Type casuses control a lot of misreferences and program in the block diagram errors

    In LabVIEW 2010, I have a Def Type control i.e. a Cluster with several other controls within the Cluster. Apparently, the references to the controls in the block diagram are based on the order that the controls have been added to the Type definition command. The side effect of this is that if a control is removed from the command of Type definition, many of the done Variable reference in the block diagram or now either broken, or worse still, refer to wrong control in the Type definition. These problems are quite difficult to find and fix.

    Comment: If you create a control of Type definition and make a Cluster. Now add any controls to the Cluster in an order, let's say A, B, C, D. Their types does not matter. Now use the Type definition in one or more controls on the front panel. In the block mark references to controls inside the Type Def would control on FP. Now return to the Type definition and remove the command B of the definition of Type. Now, lots of errors appear. Broken links. But worse still, you see old references to B that now refer to C and old references to C are now referring to the old references to D and D are removed altogether, etc..  This side effect is much more errors, broken links and misreferences than expected otherwise.

    How add and remove controls anywhere in a Cluster in a Type definition, at will, without creating a whole bunch of errors in program, broken links and misreferences for controls in the Type definition that have not changed?


  • color of the text decoration, change programmatically

    Hello

    I have a VI with a text on it (not a chain). Is it possible to change the color of the text programmatically?

    I can change the color of the background of the text using nodes property to determine its decoration Ref, wiring and then the new values of color to the property "color".

    A similar stated is possible to set the color of the text?

    -i realize I could achieve something similar by replacing text areas FP with indicators of chain and ownership of wire knots, but would prefer not to have to at this stage!

    See you soon,.

    Although the decoration of the façade have no icons of block diagram, it is possible to change some of their properties. If you access the list of properties of the Panel before decorations [], you can return references to each element of the façade decoration. However, the list of available properties for the decorations of the façade is limited, so identify your decoration will be difficult.

    One possibility would be to perform a cast of a decoration > classroom text and verify the error. If this means no error then you know you've found yourself a text decoration. Then, in a case of no error, check the text property against the decoration you are looking for. If it matches, change the color of the text property.

    Of course, don't forget to close all references (my example is unfinished, but works ok).

    Think video drivers especially if it may be others. Refer to the section of driver in my credits

    Cause

    A driver tried to access a pageable (or that is completely invalid) address while the IRQL was too high.

    This bug check is usually caused by drivers who used a wrong address.

    If the first parameter has the same value as the fourth parameter, and the third parameter indicates a runtime operation, this bug check was probably caused by a driver who was trying to run code when the code itself has been paginated outside. The possible causes for the error page are:

    • The function was marked as pageable and was operating at an IRQL higher (including obtaining a lock).
    • The function call was made to a function in another pilot, and that this driver has been unloaded.
    • The function was called by using a function pointer that was an invalid pointer.

  • Is it possible to change the definition of LOV uses dynamic action?

    Hello

    I have a multiple selection LOV page article, P27_MULTI_CLASS_CODE, defined as below.  The loading of the page, this list contains only values based on what was passed to P27_OLO_CODE or P27_OLO_CODE_SW.

    SELECT DISTINCT c.class_code d, c.class_code r

    O ORGANIZATION,

    POSITION p,

    CLASS c

    WHERE o.org_wk = p.org_wk

    AND p.class_wk = c.class_wk

    AND o.org_active_flag = 'Y '.

    AND p.pos_active_flag = 'Y '.

    AND c.class_active_flag = 'Y '.

    AND (o.olo_code =: P27_OLO_CODE)

    GOLD o.olo_code =: P27_OLO_CODE_SW)

    ORDER BY c.class_code ASC

    Before submitting the page, I want the definition of LOV's P27_MULTI_CLASS_CODE to change the following (similar application without reference to the P27_OLO_CODE or P27_OLO_CODE_SW) based on the question if the user selects a checkbox, P27_ALLOW_SW.   In doing so, P27_MULTI_CLASS_CODE would contain a wide range of values, rather than the limited values.

    SELECT DISTINCT c.class_code d, c.class_code r

    O ORGANIZATION,

    POSITION p,

    CLASS c

    WHERE o.org_wk = p.org_wk

    AND p.class_wk = c.class_wk

    AND o.org_active_flag = 'Y '.

    AND p.pos_active_flag = 'Y '.

    AND c.class_active_flag = 'Y '.

    ORDER BY c.class_code ASC

    I wanted to avoid writing Javascript.  Is this possible using dynamic measurements... or at least somehow update P27_MULTI_CLASS_CODE so that it ignores the P27_OLO_CODE and the P27_OLO_CODE_SW?

    Tried to create dynamic action to clear the value of P27_OLO_CODE or P27_OLO_CODE_SW, in the hope this would trigger P27_MULTI_CLASS_CODE to display all the values, but it has failed.  Any ideas?

    APEX 4.2

    You can do this by editing the query lov a little:

    SELECT DISTINCT c.class_code d, c.class_code r
      FROM ORGANIZATION o,
           POSITION p,
           CLASS c
    WHERE o.org_wk = p.org_wk
       AND p.class_wk = c.class_wk
       AND o.org_active_flag = 'Y'
       AND p.pos_active_flag = 'Y'
       AND c.class_active_flag = 'Y'
       AND ((:P27_ALLOW_SW = 'Y' AND (o.olo_code = :P27_OLO_CODE OR o.olo_code = :P27_OLO_CODE_SW))
            OR :P27_ALLOW_SW = 'N')
    ORDER BY c.class_code ASC
    

    (of course, use the correct value for P27_ALLOW_SW)

    The "cascade LOV Parent article (s)" value P27_ALLOW_SW and also add "Page elements to submit" element (Note: this item appears only when you have entered a value in the element of parent lov cascading items)

    Now, after changing P27_ALLOW_SW the lov will update to P27_MULTI_CLASS_CODE.

  • Apex 4.0: In the form of table: how to make reference to the elements?

    Hello
    I have a tabular layout with a certain query. A column in the query (say comm, is not displayed. This column is required in the table

    When a new row is added in the form of tables, I want to add a (complex) value for this column hidden by default.

    I want to add a process (before submitting) to the page.
    How can I make reference to this particular point?


    : P23_COMM: =...

    does not work. It is a column in the query, not a page element.

    Any help appreciated.
    Sincere friendships Erik

    Loop over the hidden PK table, identification of the new line (by finding with PK NULL table th eone) and assign the hidden item corresponding

    Assumung 01 is the primary key column table (use firebug to check this) and 05 is the hidden field

    BEGIN
      FOR i IN 1..APEX_APPLICATION.G_F01.COUNT
      LOOP
         --Identify new rows
          IF ( APEX_APPLICATION.G_F01(i) IS NULL ) THEN
              APEX_APPLICATION.G_F05(i)  := 
          END IF;
      END LOOP;
    END;
    
  • NULL REFERENCE ERROR

    I have a movieclip that is playing a game when it's the button is clicked. I have the code in my "Home" button, which removes the game from the scene, if you click on it after you start a game. However if I click on my home button (or any button with my deletion indicator) without playing the game first I get:

    TypeError: Error #1009: cannot access a property or method of a null object reference.
    at mikesPlayhouse_fla::MainTimeline/onHomeClick()

    How can I fix it? My code to remove the game follows. Thank you!

    Oh, I think I understand your problem. If I understand you right, your problem is:

    (1) you run the game once, and it creates puzzleBoardClip and holder
    (2) you click the home button, and it removes puzzleBoardClip and holder successfully
    (3) you click the home button again and it fails.

    If that is correct, I believe that the desired correction is simply to puzzleBoardClip and door on a null value when you click the home button. for example

    function onGamesClick(event:MouseEvent):void {}
    this.gotoAndPlay ('games');
    SoundMixer.stopAll ();

    If (puzzleBoardClip! = null) {}
    removeChild (puzzleBoardClip);
    puzzleBoardClip = null;
    }
    If (owner! = null) {}
    removeChild (holder);
    owner = null;
    }

    }

    In this way when you click on it a second time, conditional statements inside the IF statements (if (puzzleBoardClip! = null) may be distorted and he won't try again to remove the clips.)

    Note that you should show these null instances in this way _anyways_ so that the garbage collector frees the memory taken up by the puzzleBoardClip and support when they are no longer needed.

  • A file in a source path must have the same package structure ", as the definition's package?

    How I can fix this bug with my class, I get this message:

    "A file in a source path must have the same package structure", as the definition, "photoviewer" package. "

    It's my source WindowedApplication:

    This is my Gallery class source:

    Import mx.collections.ArrayCollection;
    Import mx.collections.IViewCursor;

    public var description: String;

    private var photo: Photo;

    public void Gallery (gallery:Object = null)
    {
    photos = new ArrayCollection();
    If (Gallery! = null)
    {
    Fill (Gallery);
    }
    }

    public void fill(gallery:Object):void
    {
    myIdName = gallery.id;
    This.Description = gallery.description;
    This.Selected = 0;

    for (var i: int = 0; i < gallery.photo.length; i ++)
    {
    Photo = new Photo (gallery.photo );
    photos.addItem (photo);
    }
    }
    }
    }

    Someone knows how to fix this error?
    "A file in a source path must have the same package structure", as the definition, 'photoviewer' package. '?

    Kind regards

    Yes. If you want to file package photoviewer Gallery you create directory photoviewer in src and move the file there.
