definition of dataProvider

I'm trying to change the data displayed in a ColumnChart when the user changes the value in a DateField. I initialize the fromDateValue variable and then compare it to the current value of the DateField control. When it is different, I try to update the dataProvider of the graph.

Event handler for the DateField change event.
private void dateChanged(date:Date):void {}
If (date is nothing)
Alert.Show ("date == null'");
on the other
If (fromDate.text! = fromDateValue) {}
podcastCategoryChart.dataProvider = "{podcastCategories02}";
}
}

< mx:Array id = "podcastCategories02" >
< mx:Object data = '3' label = "Comedy" / >
< mx:Object data = '0' label = 'Debate' / >
< mx:Object data = "4" label = "Design" / >
< mx:Object data = "4" label = "Magazine" / >
< mx:Object data = '3' label = 'Science' / >
< mx:Object data = '3' label = "Self-help" / >
< mx:Object data = '8' label = 'Technology' / >
< / mx:Array >

Unforunately, the result of this is that all, but the drop-down list control fromDate freezing. The DateField text fromDate is not up-to-date, but the drop down menu appears.

Is there a better way to update dataProviders?

TIA,

David

If it should not be:

podcastCategoryChart.dataProvider = podcastCategories02;

  • 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!

    Aaron

    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.

  • Definition of clear page before generation

    Hello
    I created a methodAction of links on a Page definition of data binding that
    have erased every time I run generator applications.

    In JHeadstart tutorial I found that there are two ways to preserve the link graph that has been added to the definition of the page
    -Uncheck the box "definition claire page before generation.
    - and to add the binding to the model.
    #macro (CUSTOM_BINDING)
    #end
    ${JHS.pageDefGenerator.addBinding ($JHS.page, "< data collection >", "#CUSTOM_BINDING ()")}
    in my case I have element with the type without calling method commandButton control. I changed the jsff generated page and define the action of the managed bean method button.

    If I just think I need to add the tracking code:
    #macro (CUSTOM_BINDING)
    < methodAction id = "f_url_porocila".
    InstanceName = "AppModuleDataControl.dataProvider"
    DataControl = "AppModuleDataControl" RequiresUpdateModel = "true".
    Action = 'invokeMethod' MethodName = "f_url_porocila."
    IsViewObjectMethod = "false".
    ReturnName = "data. AppModuleDataControl.methodResults.f_url_porocila_AppModuleDataControl_dataProvider_f_url_porocila_result">
    < NamedData NDName = "p_sifra_porocila" NDType="java.lang.String"/ >
    < NamedData NDName = "p_parametri" NDType="java.lang.String"/ >
    < / methodAction >
    #end
    ${JHS.pageDefGenerator.addBinding ($JHS.page, "MetAplikativniModulView1", "#CUSTOM_BINDING ()")}
    'MetAplikativniModulView1' being the collection of data for the option group "AplikativniModul".

    Is the collection of data <>inside
    ${JHS.pageDefGenerator.addBinding ($JHS.page, "< data collection >", "#CUSTOM_BINDING ()")}
    right?

    I am looking for the model vm I should change if I can get the box ' page clear definition pre-build "checked.

    Kind regards
    Dejan

    Dejan,

    The second argument of the call to addBinding should have the same value as the id of the action of the method:

    ${JHS.pageDefGenerator.addBinding ($JHS.page, "f_url_porocila", "#CUSTOM_BINDING ()")}

  • Definition of the data to a chart

    AS:

    Hi all

    I'm new to Flex but have a simple question about the definition of the data to a bar chart.  Curious, the code below the values in my BarChart become every 4 because of the link to the table?  If MyArray is local to the button click function, which only becomes a problem when execution leaves the service since the DataProvider will demonstrate to a table that does not exist.  Although it seems not work properly.  Thanks Bob

    protected function button1_clickHandler(event:MouseEvent):void
    {
    TODO self-generating method stub
    var MonTableau: Array = new Array();
    MyArray [0] = 1;
    MyArray [1] = 2;
    MyArray [2] = 3;

    Series1.DataProvider = MyArray;

    barchart1.invalidateSeriesStyles ();

    MyArray [0] = 4;
    MyArray [1] = 4;
    MyArray [2] = 4; }

    MX:

    < mx:BarChart = "27" x y = '91' id = 'barchart1' height = '259' type = 'bunk' >
    < mx:series >
    < mx:BarSeries id = "series1" displayName = "Series 1" xField = "" / >
    < mx:BarSeries id = "series2" displayName = "Series 2" xField = "" / >
    < / mx:series >
    < / mx:BarChart >

    Basically, when you say series.dataProvider = myArray, the source property of the collection object that is created will have a source property which will reference the same memory (say 0x000000) referenced by myArray.Whenever you say MonTableau [0] = 5, you change the memory referenced by the handle myArray.Therefore, the change will be reflected in the collection too. When the function ends, what happens is that the handful of myArray to memory 0 x 000000 is lost. But the content of the memory will remain as there are a handful through the source of the collection.

    It's my explanation for the scenario. I guess it's okay. In my view, it is best to confirm with other experts in the forum before coming to a conclusion.

  • Restrict the dataProvider of drop-down list box to display a field.

    Hello

    I wonder if there is a way to use an ArrayCollection collection as the dataProvider for a ComboBox but only allows him to display a field as you can do with a DataGrid control by using the dataField on the column definition property.

    So, let's say I have a collection of letters and numbers ArrayCollection, and I want the ComboBox control to display only the letters.  Is it possible to specify this?

    Thank you!

    Use the labelField property to specify the field of ComboBox dataProvider to display in the ComboBox control.

    This means that you have the items in the collection ArrayCollection which are objects or XML, etc.

    If this post answers your question or assistance, please mark it as such.

    If I open a new file in Flash (AS3) in Flash CS3 Professional and try to import the DataProvider (import fl.data.DataProvider;), I consistantly receive a compile error (1172: definition fl.data:DataProvider could not be found). Does anyone know what is the problem?

  • Dictionary find definitions

    Hello

    Since the installation of Sierra, I experienced some problems with the Dictionary application. I'll try to explain this in the least difficult way possible. So whenever I try to do a quick search of dictionary-based on Spotlight, Spotlight gives me no results for dictionaries monolingual English. This means that if I have the New Oxford American Dictionary and its corresponding Thesaurus, Spotlight do not think everything about these dictionaries and keep will show the results of dictionaries, I disabled it, which in this case is the bilingual Italian-English Dictionary. Now, as much as I appreciate see entries from the dictionary being translated in my own native language (Italian), I would also like to see the entries in the monolingual dictionary on Spotlight, I strongly need for my work. In short, I'm looking for something similar in view of that context when menu shows you yellow - highlight a Word while, for example, surf Safari. I have no problem with context menus because they show all the dictionaries that are enabled in the dictionary application preferences window. To summarize, it looks like that Spotlight does not recognize these two American dictionaries (I also tried with a Dutch-English Dictionary) and continues to find definitions for the bilingual. This phenomenon happens to you too much on the Sierra? I would also add that, as a countermeasure, I did the following: deleted the file com.apple.Spotlight.plist in the folder of user library, re-indexed Spotlight, tried on a new account user without result, disabled the definitions in Spotlight, moved preferences box and down the dictionaries selected in the pane preferably small in the dictionary.

    I appreciate your comments,

    Francesco

    The question I did experience is otherwise.

    I depend a lot on the context dictionary and see that it is missing, once upgraded to 10.12 is a bit annoying, not because I can not find how to fix it (because I think I have), but I'd need to know where to do this. Whenever I write a strange word, I try to make sure I use it properly. However, when I 'Look Up' a Word, I get a wikipedia article on a group of rock or something unrelated, like the component dictionary was gone by default.

    Only by reading this thread I was able to launch the dictionary application - which immediately began to download a copy of the New Oxford American Dictionary. I guess my next task is to find an easier to apply dictionary (Canadian) and understand how to install it.

  • Definition of Spotlight on macos Sierra

    Hello

    I had been using spotlight to search for words in El Capitan without any problems before. However I just upgraded to Sierra and spotlight returns no definition of the word. I did a clean install, but no changes in the light of the preferences. All options are selected as they come by default. It was a feature that I used all the time and it helped me so much. All the solutions I could try?

    Thank you.

    Hi agokgoz!

    I see that you are unable to search using Spotlight definitions under macOS Sierra.  I know it's important to have the ability to look up definitions of words in Spotlight, and I'm happy to help you.  In order to further isolate the issue, please create a new account manager and test to see if the problem persists in the new user account.  Here are the instructions to do this:

  • What is an overview of the link? I want just a definition, please. Not questions of others.

    I am a user of office. You keep changes to make me safer, which is good. But I really need a clear definition of your requirements. I don't know many of them. PREVIEW OF THE LINK. Taskbar. None of these bars are labeled. I DON'T necessarily know what they are called. Covered things upward with a single bar on top of the other much of the time. I clicked on all bars and never found your explanation. Q? There is a dictionary of terms? For all terms, IE. all names and verbs in comupterese?

    Preview of the link is probably added by an extension and shows an image of the page in the link in a small pop up if you hover over a link.
