Update a property bindable class does not cause control to update

I'm having a problem with data binding. When I update a property in a class that has bound it controls, these controls are not refreshing their display value with the new value of the property automatically and I don't know how to force them to do so.

Here's how I implemented ActionScript class:


[Bindable] private var __dataSource:String;

The get/set accessor is declared as follows:


[Bindable] public function get dataSource (): String {}
Return __dataSource;
}

public function set {dataSource(dataSource:String):void}
data source = __dataSource;
}

So, I have an application mxml with the following variable to this ActionScript class declaration:

[Bindable] private var __reportDefinition:ReportDefinition;

The text in the mxml control is defined as follows:

< mx:TextInput id = text = "{__reportDefinition.dataSource"txtReportTitle"}" styleName = "textInputStyle" width = "259" / > "


OK, back to the ActionScript class, I have a function that executes the following line:

__dataSource = "SomeValue";

After this line, the text entry is not refreshed. I checked the text input control relates to the correct instance of the object of action script.

Any tips? Thank you



You run into the question https://bugs.adobe.com/jira/browse/SDK-14778

The workaround described in the question, but I encourage you to vote in favour, while it has more chances of is fixed in the next version of Flex.

  • kb2596615 causes ade to failure, error was 459: object or class does not support the set of events

    A couple of my users started getting our application error messages ade grown after you apply this update. Everything is well after its withdrawal. First mistake was 459: object or class does not support the set of events. Basically, no event has worked. Why is this update break my application? It should be removed from the queue of the update.

    Okay, I've worked on it with Microsoft, and the actual cause turns out to be:

    MS12-060 security update affects the functionality of Access database
    http://support.Microsoft.com/kb/2748410

    This article updated fingers MS12-060, specifically KB 2687441, as the culprit.

    It turned out that ActiveX controls on the form (specifically the Microsoft Common Controls 6.0 Toolbar), caused the failure.

    The solution was simple: on a patched machine, open each form with an ActiveX control in design mode, compile and save it. It worked for me. Ignore the details of the solution that I wrote in the previous post!

    You may need to resave MSCOMCTL. OCX, as suggested in the article, to get your databases to work.

  • "For more specific class" does not not on sbRIO 9636

    The application that I am forcing me to programmatically access arbitrary components of a nested group. Currently, I am doing the browsing the cluster using his property [] node recursively controls. Currently, my accessor VI to accomplish this works very well on a normal PC but does not work on my target in real time, a sbRIO 9636.

    After some research, I determined that the function "To more specific class" does not work on my target in real time. I have attached a code base that shows the heart of the problem. It works fine on a PC but will return an error 53 when running on my target in real time.

    A few questions:

    (1) is 'To more specific class' supported on the sbRIO 9636 or not?
    (2) if it is supported, what am I doing wrong?

    (3) if it is not taken in charge, what are other methods for access by the arbitrary elements of a nested cluster program?
    (4) if it is not supported, why LabVIEW allows me to place the feature even when the sbRIO 9636 is explicitly selected as my goal in my LabVIEW project? It seems prudent to restrict its use, if it is not supported. My day job has been effectively wasted because of this problem.

    For reference, here's a few previous discussions

    The other posts are correct, because it is currently not possible to use the function on a real-time target. This is a known issue and is being investigated for correction, but currently there is no work around. It is available on the pallets that this behavior is not intentional and should work.

    You have described your application requires that recursively through a table and access to specific data. Does this mean that the Data Structure might be different when the vi is run and you need to adapt to a changing data type? If this isn't the case, then all you need to do is to get the value of the reference and then ungroup the cluster as needed then store the changed values to the same reference.

    If you're going to have to settle you will encounter difficulties to be determined pragmatically you should do but I have a suggestion. Create a cluster with an enum and a Variant. You can use the enumeration to set the type of the variant in question. He chooses the type to convert the variant according to the code. It is a similar structure, like messages in queue manager and his messages that happening except that you will be passing a reference to this group that has both the message and the payload in one. The reference could be used to get the value and then the code must only be written to accept the Cluster of Enum and variant you can then convert the variant to the appropriate type for later use. For best performance, you also use in Place of the Structure element.

    It's only a means potentially accomplish what you want. If you describe your program and needs more in depth, we are able to offer a more suitable solution for your application that does what you need. I wish you a nice day!

  • Why the parent class does not report data for child in LVOOP class?

    Attached is a practical program that I wrote to learn about the legacy with LVOOP.

    I have the impression of OOP is a Parent class describes the type of object.  Then the children inherent description of the parent.  The child may also have additional qualities, but it still contains the description of the parent.  If a child does not have a VI bearing the same name as the parent and the parent VI will be loaded and executed.

    My questions:

    (1) why does the Parent.lvclass:Read.vi not report 'Child' in the channel indicator when the child write VI has been sent?

    2) matches the data of the child, do not at all seen by the parent company even when it has the same definition (that's the String)?  I understand that the Parent do not know anything about the unique child elements, but I think we should know about the common themes which inherited the child.

    Here is my sample code:

    These are two different sets of data. The parent class has a data set containing the string, the class of the child also has a data set containing the string, but both of these channels are separated.

    This can be made apparent, by changing the names of the channels based on their respective categories:

    What you want is for your children, class VI write to access the data of the parent class. You can do this with a simple data VI member access in VI of the child:

  • t:div survey property component class is not writable

    I use the div of Tomahawk, include the rendered attribute to check if the packaged components must be returned. An exception is thrown indicating that the property of the component is not writable. In other words, I think it means that there is no set method. However, there are. I also use the same expression in t:inputText / t:outputText element/s where it works.
    What is so specific with the t:div?
    I wonder also why there is a necessary set method because I don't use it...

    If it says "class of component property is not writable" maybe he's talking about the property of the 'class '? not 'made '.

  • OOP CLASS DOES NOT STOP?

    Hey,.

    I think it is the execution of a line of code to leave class when it is finichsed...

    removeChild (enemy1); -It does not work to get rid of my items in my framework of actions.

    Help, please

    See you soon.

    then removeChild (object) will remove this class.  But if you have added any displayobjectcontainer, other than 'this' objects, you must explicitly remove these objects using a method in your class.  Create it if it does not already exist.

    or, even easier, just add objects to 'this' in your class.  but you should complete loops and streams when your class object is removed from the scene and hasn't needed to run the code.  Use the removedfromstage event. to trigger.

  • Radio button problem: selected property of Option does not work

    I want an Option among two options in the radio group to be selected by default at the beginning of the application.

    Here are the ways I've tried.

    using QML:

    {Page}
    content:
    {Of container
    RadioGroup {}
    Option {}
    selected: true
    text: 'feminine '.
    value: female
    }
    Option {}
    text: 'Male '.
    value: male
    }
    }
    }
    }

    using RPC code:

    QmlDocument * qml = QmlDocument::create ("main.qml");
    AbstractPane * root = qml-> createRootNode();

    RadioGroup * group = RadioGroup::create () .add (Option::create () .text ("option 1").selected (true)) () .add
    (Option::Create () .text ("option 2")) .add)
    Option::create () .text ("option 3"));

    Application::setScene (page::Create (). Content (Group));

    in both directions, I get options with text, but default selection is not made.

    Use quotation marks for the value tag.

    If this does not help, you can try this:

    RadioGroup

  • class does not not with the document class

    I created classes that is available to my level. So level 1 includes a table like:

      floor1[0] = [2,1,1,1,1,1,2];
      floor1
    [1] = [1,1,1,1,1,1,1];
      floor1
    [2] = [1,1,1,2,1,1,1];
      floor1
    [3] = [1,1,1,1,1,1,1];
      floor1
    [4] = [1,1,1,2,1,1,1];
      floor1
    [5] = [1,1,1,1,1,1,1];
      floor1
    [6] = [2,1,1,1,1,1,2];

    And level 2 would contain a different as configuration:

    Floor2 [0] = [1,1,1,3,1,1,1];
    floor2[1] = [1,2,1,3,1,2,1];
    floor2[2] = [1,1,1,3,1,1,1];
    floor2[3] = [1,1,1,2,1,1,1];
    floor2[4] = [1,1,1,3,1,1,1];
    floor2[5] = [1,2,1,3,1,2,1];
    floor2[6] = [1,1,1,3,1,1,1];

    Here's my problem. These classes are not connect with my document class. My document has an empty array named createFloor which will equal level 1 first. Once this level is completed, it will be equal to floor2 and so on. The code is below:

    for (var y = 0; Y < createFloor.length;. Y++)

    {

    for (var X:int = 0; X < createFloor [Y] .length; X++)

    {

    var cell: MovieClip = new Tile (X, Y);

    cell.gotoAndStop(createFloor[Y][X]);

    Cell.x = ((X-Y) * tileh) 365;

    Cell.y = ((X+Y) * tileh/2) + 70;

    addChild (cell);

    cell.addEventListener (MouseEvent.CLICK, mouse click);

    cell.addEventListener (Event.ENTER_FRAME, onGame);

    }

    }

    I don't know how to get the document classes and level to talk with each other. I tried to do the level class to extend the hand, but I fugre that had nothing to do with it. All ideas

    change your class Level1:

    package {}

    import flash.display.MovieClip;

    SerializableAttribute public class extends MovieClip {} Level1

    public var floor1:Array;

    public void Level1() {}

    Level 1 = new Array();

    LEVEL 1 [0] = [2,1,1,1,1,1,2];

    LEVEL 1 [1] = [1,1,1,1,1,1,1];

    LEVEL 1 [2] = [1,1,1,2,1,1,1];

    LEVEL 1 [3] = [1,1,1,1,1,1,1];

    LEVEL 1 [4] = [1,1,1,2,1,1,1];

    LEVEL 1 [5] = [1,1,1,1,1,1,1];

    LEVEL 1 [6] = [2,1,1,1,1,1,2];

    }

    }

    }

    until level 1 is in the same directory as your document class, in your document class you can use:

    private var level1:Level1 = new Level1();

    trace (Level1.Floor1);

  • Bindable XML does not always...

    Hello

    I started on an element for a game I'm developing, and I met a problem: JavaScript was not going to do the job, so I went for Flex.

    The item in question consists of boxes with items. A bit like a storage area. Each box is an element of mx:Panel with a mx:Grid inside for the slots.

    The mx:Panel title is linked to the boxes... name, where the boxes is an XML object that is loaded from http://pokefarm.adamhaskell.net/boxtest.xml. This method works.

    What does not work is the mx:Image elements in each mx:GridItem. Source of the image (for item 1 in zone 0) is related to the boxes... box0.pkmn1.img. When compiling, I am told that the 'src' attribute cannot be resolved.

    No idea what is happening?

    Thank you.

    MX:image has a 'source', not 'src' attribute

  • Writing to the nodes property DAQmx channel does not refresh the channel values

    Hi all

    I have a riddle.  I created a task programmatically in LabVIEW and programmatically added several analog input channels to the task.  It's easy.

    I wish that my user must be able to modify the individual channels within the task.  To this end, I created a set of screws that allow it to change the settings appropriate to the channel (for example, if it is a channel of thermocouple, it can change the type of thermocouple, CRC value, etc... If it is a strain gauge channel, it can change the coefficient of fish and so on).  These screws all works beautifully, like the VI where they live.

    The specific question that I have is that writing to the channel property nodes refreshes not communication channels.  See the images below.  The first image is the code that needs to define new channels of communication:

    Note that immediately after setting the property nodes, I read their values back, just to see what comes out back.

    The second image is an image of the public Service immediately after the execution of this VI.  Note that the values read from the channel property nodes did not updated to match to the set of values, but instead kept their initial configuration values:

    What I am doing wrong?  I fought this for a few days now and I'm stumped.

    Thanks for your time!

    Diane

    Hi, Diane.  A week ago, I also had a problem changing the channel properties (not sure that our situtions are exactly comparable, but...).  My 'solution' to want to change the appearance of the task was to just throw the original task and recreate all the elements of the task from scratch.

    I've not done enough 'experiments' to work when you can and cannot change, but am now much more cautious...

    "First of all, use the formatting code"
    I don't know where he is.

    Already answered - in a much more civil way I wish!

    and also I already explain what im trying to do maybe didn't it read the comments in my code and the bellows of my last code message. I have already explained my problem.

    I did not read your comments either, because the code was not formatted (hard to read =). And because nothing in the text of the proposed non-code that there comments in code that has highlighted the problem.

    Im trying to update the label text using myPanel.java label.setText using stateChanged tabPane in Frame1.java
    look at my code earlier there is a code like that (...)

    The code you cite here is irrelevant. The problem is in the event listener:

    public void stateChanged(ChangeEvent evt){
      int currtab = tab.getSelectedIndex();
      System.out.println("Frame1: "+currtab); //<- it works
      new myPanel(currtab);
      //new myPanel(new JLabel(),currtab);
    }
    

    So whenever you change your tab, you create an instance of myPanel, that is strange in itself; but worse yet, what are you doing with the newly created group? You don't add it anywhere. What then is this instance?
    The code proposes label.setText (...) is in the constructor of mypanel, but it changes the text of the new label in the new Panel, not existing the existing label in the Panel text.

  • Why the datasize property settings node does not

    The documentation says that this property is available on a read-only basis in the runtime. What I am doing wrong?

  • T420 (and others?) Management BIOS WMI class does not

    We deploy Windows 7 for laptops Lenovo Microsoft SCCM. We should change a few portable on any computer BIOS options, more importantly enable the TPM for Bitlocker.

    I read the BIOS Lenovo Windows Management Instrumentation Interface document and tested provided example scripts. "cscript.exe SetConfig.vbs SecurityChip Active" seems to work as expected, and so do some other settings such as disabling modem, fingerprint reader etc. Run the ListAll.vbs script after modifying the parameters with SetConfig.vbs prints the correct values changed, so something to be saved.

    However, after restarting the laptop, the BIOS settings are back as they used to be. The system reports even "Change Configuration, restart the computer" or something like that when it restarts, and all seems fine but... The settings just not being saved or not change does the same. After the reboot, ListAll.vbs also reported the original settings.

    Any ideas? Should not SetConfig.vbs save the settings when it applies to them?

    The problem has been verified to exist at least the T420, but we did not test other models yet so I can't tell if it's the spesific model. I think I also didn't test change a single setting, we changed a couple of them at the same time. I'll test this tomorrow, but I don't think that explains the problem either?

    Have you tried to update the BIOS to the new version?
