First choice in ObjectChoiceField do not call FieldChangeListener.

Hello everyone, I have a choice of object field to display a list of the cities. I gave the initial value for field as the first city in the list of cities. I put the changes for the field and hadling the event listener using fieldChanged().

I use getSelectedIndex() to treat the choice more far. When I choose choice other than the first (0th position choice), it works fine. But when I choose the first, nothing happens. I debugged n saw that control comes not at all to the fieldChanged() method.

My code is as below:

mCityDropDown.setChangeListener (new FieldChangeListener() {}
            
' Public Sub fieldChanged (field field, int context) {}
                
if(Context == 0) {}
return;
}
UiApplication.getUiApplication () .invokeLater (new Runnable() {}
                        
public void run() {}
Dialog.Inform ("Index:" + mCityDropDown.getSelectedIndex ());

}
});

}

});

Can anyone tell if I am wrong somewhere n suggest me the solution. Thanks in advance.

The default value of the change listener, it fires if something is changed.
as the index is 0 before AND after there is no change.
You must adapt your application logic to that.

  • Default method of workflow activity is not called when the Page refreshes

    Basically, try to call a script function java front page of fragments of the charges.

    INSTALLATION PROGRAM:

    Jdev 12 c

    TF defined with a default activity that invokes a page fragment.

    The activity of default method calls a method to support bean which inturn calls the method init java script before the fragment on the page doesn't load.

    This TF is in a container jsf page.

    During the loading of the page containing the first activity of the method is called and js function triggers and then fragments of charges which is the desired behavior.

    PROBLEM:

    When I refresh the page by pressing F5 or by running the page again on the same window of the browser activity method default IS NOT gets called which inturn will not trigger the js call.

    But when I run the same page again in a different window it works and then subsequent updates or page load activity IS NOT of default method is called.

    If it is not provided? The default activity is called when the workflow is updated.

  • JavaFX 2.2 initialize is not called when using ControllerFactory

    Is there a reason why the initialize method is not called when specifying a controller factory (by calling FXMLLoader #setControllerFactory) instead of an instance of a controller (via FXMLLoader #setControllerFactory)? By the "initialize" method, I mean one of the following:
    public void initialize()
    @FXML private void initialize()
    @Override public void initialize(URL, ResourceBundle) /*as defined in the Initializable*/

    First of all, I'm not using the static version of the load method. I call class #getResourceAsStream not the #getResource class.

    Well Yes, you are right. I read it too fast. See? Source of confusion. ;-)

    But just to repeat what said Tom - Yes, fx:controller is always necessary, even if you specify a controller factory. The type specified by the fx:controller attribute is the type that is passed to the factory. If you do not specify a type of controller, then the plant is not called.

    Call it a guess, you're not the first to fall into the trap of the nested :) form Its too easy to simply slap a high h:form somewhere near the top of the tree and forget it.

    For the future: remember that the browser is actually doing the work when you submit a form. If something goes wrong, it appears in the HTML source as you can see by using the function "view page source" from the browser. It pays to know HTML and especially the limits if you want to understand such things by yourself. When you locate the faulty HTML code, it is usually not so hard more to trace what is bad in the JSF source.

  • Copy and code pasted, first code works, second is not. Why?

    I've literally been watching this for 7 hours. I'm missing something.

    I have two clips on the stage. The name of the first instance is puzzleAK. The name of the second instance is pieceAK.

    The first relates to a custom class called GeoPuzzle. The second relates to a custom class called Geocoin.

    The code is compiled, but throws an error (as explained).

    The code in the main timeline:

    puzzleAK.fullName = "Alaska".
    puzzleAK.abbrev = "AK".
    puzzleAK.isLocked = false;
    trace ("done through definitions of puzzle:" + puzzleAK.fullName + "" + puzzleAK.abbrev + "" + puzzleAK.isLocked);

    It's the last track that makes it properly through. the code on the main timeline stops execution here and raise an error 1009.
    pieceAK.fullName = "Alaska".
    trace ("done through definitions of name full pieceAK:" + pieceAK.fullName);
    pieceAK.abbrev = "AK".
    trace ("done through pieceAK abbreviation definitions:" + pieceAK.abbrev);

    The code in Geocoin:

    SerializableAttribute public class extends MovieClip {} Geocoin
    public var abbrev:String;
    public var fullName:String;

    public void GeoPiece(): void {}

    This code executes correctly. The currentLevel is set correctly (in another class) and the clip goes to the right frame.
    If (PuzzleGlobals.currentLevel == "Name") {}
    this.gotoAndStop ("fullName");
    }
    Else if (PuzzleGlobals.currentLevel == 'Abbrev') {}
    this.gotoAndStop ("abbrev");
    }
    Else if (PuzzleGlobals.currentLevel == "Shape") {}
    this.gotoAndStop ("shape");
    }
    Else if (PuzzleGlobals.currentLevel == 'Flag') {}
    this.gotoAndStop ("flag");
    }

    It is added properly. The beginning and the touch move functions enable and allow the piece to slide.
    this.addEventListener (TouchEvent.TOUCH_BEGIN, geoPieceBeginHandler);
    }

    public void geoPieceBeginHandler (e:TouchEvent): void {}
    e.target.addEventListener (TouchEvent.TOUCH_MOVE, geoPieceMove);
    MovieClip (this.parent).nameDisplay.gotoAndStop (e.target.abbrev);
    trace (e.target.abbrev);
    }

    public void geoPieceMove (e:TouchEvent): void {}
    This.x = e.stageX;
    This.y = e.stageY;
    }
    }

    What Miss me? Assignments to variables are exactly the same for each class. I had them named different things, too (fullName1 and abbrev1) to see if I was getting variable contradictory since they are public and I come from a different background and haven't brought not a solid understanding of the way the flash compiler handles. But that didn't change anything.

    What I am doing wrong?

    Thank you!

    Flash don't think that pieceAK exists when your code runs.

    There are a number of ways that can happen even when you click on the stage at frame 10, see pieceAK in the properties panel.

    There is one way to ensure that the error does NOT occur: find the first key frame when there is some pieceAK and make sure that there is no other keyframes after that, in which pieceAK are.  Repeat the test.  When it's ok you can then add keyframes after the first, if necessary.

  • TreeView not called ApplyDataToWidget()

    Hi all
    I just tried to change the example SDK «WListBoxComposite» program My change was instead of display the treeview in a Panel widget, I tried to show the treeview widget in a dialog box.

  • The file reference does not call. upload()

    OK it's going to take a little bit to explain but stick with me:

    I have two layers in the timeline, with no keyframes (coucheUn) and the other with a picture any key for every frame in the layer (layerB).
    In coucheUn, I have the script action to declare a variable of FileReference and I also declare and attach a listener object to the file reference.
    The listener object detects the event .onSelect to the FileRefernce (this event is generated when the service. the FileReference class's browse() is called - which opens a file browser and allows you to select a file). When called onSelect listener object executes the function. upload() FileReference which analyzes the file selected to a php script that downloads the file on my server.
    Function. for the FileReference browse() is called from an image in layerB. This is where the weird stuff that happens.
    When I test the movie the first time I enter the keyframe that calls the function. browse() all download routine work and the file is downloaded successfully. If I continue to the next keyframe (using navigation controls) and then navigate back and try to repeat the download process, then the file browser opens successfully, I select the file and then nothing happens. I have problems to identify the problem, for as far as I see it is as if it does never emit the onSelect event once the file is selected, which shouldn't be the case that the function .Browse works and a file is selected successfully. This would imply the php script does not work which is just ridiculous because it is a very simple script and it works the first time.
    Everyone has ideas, if you need more just information!


    UPDATE:

    Just did some tests and I'm completely confused, it's something the onSelect event. For some reason, it is not called / is not detected by the listener object. It's just weird because he calls good the first time you enter the frame, but if you navigate back, it is not detected. I checked the listener object was still in the scope of this framework and it seems to be, so I'm completely confused. The listener object is there and listening, the event that generated the onSelect event is executed but then never detected.

    Wooops, corrected just, said an another FileReference var on the following image with the same name, changed the name and works very well. Really really stupid of me.

  • The entity not called adapter not

    Hi all

    I would like to send a form of resource information to another form of resource.

    The first form of resource is updated by an approximation of the target (not approved). I ve created an adapter of entity to trigger the update record resource and wait that it runs when a new recon event is received and matched.

    What is going on:

    (a) run target Recon
    (b) information is correctly updated in the form of resources
    (c) entity adapter is not called.

    If I go to the form of resources and Edit - save (without modification), the adapter of the entity is called and tasks run very well.

    Clues why the adapter of the entity is not called automatically?

    Thank you

    Reconciliation events trigger an update to the forms. You can trigger a task of the intervention of an update of reconciliation to perform tasks you want.

    Hello

    Choose indoor walk or run Indoor (it does not matter which) to an indoor walk-run routine.

    Even if Apple Watch does not currently offer as a workout interval training, choose one of these allows the most appropriate data sources (which are the same for market and short) to use to track your training.

    If walking or running, the accelerometer is used to estimate pace and the distance (allow your arms swinging naturally) as well as the frequency heart sensor for the estimation of calories burned.

    Run or walk inside will not affect your calibration data. Calibration is based on the GPS of the iPhone data and is only held during the outdoor walking training or race outdoors when the iPhone combined is taken along.
