• Problems with the removal of the data binding Flex to use Air 14

  Hello

  I was wondering if anyone had an optimal solution to replace the Flex Air 14 data binding classes. I can't merge the Flex and Air SDKS more for all liaison managers need to be replaced. Everybody runs into this problem yet? Automated link generation and manipulation was the best feature of Flex and now that it's broken it creates huge problems for me.

  It is Air of mobile and desktop applications. They still build everything simply no work of event management.

  See you soon,.

  I forgot that I myself have solved last Dec. So basically from what I can tell that the precompiler is either no [Bindable] conversions so you must manually create the getters and setters for your model when it changes. I hope this helps anyone who may run into the same problem. There is literally no documentation on this wheres.

  i.e.

  [Bindable]

  public var username: String;

  becomes

  private var _username: String;

  [Bindable (= "propertyChange" event)]

  public function get username (): String

  {

  return this ._serviceState;

  }

  public function set username(value:String):void

  {

  var oldValue:Object = this ._username;

  If (oldValue! == value)

  {

  This ._username = value;

  If (this.hasEventListener ("propertyChange"))

  this.dispatchEvent (mx.events.PropertyChangeEvent.createUpdateEvent (Thi, "username", oldValue, value));

  }

  }

  You must also make sure that what ever class contains this property implements IEventDispatcher and has the following functions:

  	//	Implementation of IEventDispatcher
  	//
  	private var _bindingEventDispatcher:flash.events.EventDispatcher =.
  		new flash.events.EventDispatcher (flash.events.IEventDispatcher (this));
  	/**
  	* @inheritDoc
  	*/
  	public function addEventListener (type: String, listener: Function,)
  									useCapture:Boolean = false,
  									priority: int = 0,.
  									weakRef:Boolean = false): void
  	{
  		_bindingEventDispatcher.addEventListener (type, listener, useCapture,
  			priority, weakRef);
  	}
  	/**
  	* @inheritDoc
  	*/
  	public function dispatchEvent (event:flash.events.Event): Boolean
  	{
  		Return _bindingEventDispatcher.dispatchEvent (event);
  	}
  	/**
  	* @inheritDoc
  	*/
  	public void hasEventListener(type:String):Boolean
  	{
  		Return _bindingEventDispatcher.hasEventListener (type);
  	}
  	/**
  	* @inheritDoc
  	*/
  	public void removeEventListener (type: String,)
  										Listener: Function,
  										useCapture:Boolean = false): void
  	{
  		_bindingEventDispatcher.removeEventListener (type, listener, useCapture);
  	}
  	/**

  	public void willTrigger(type:String):Boolean
  	{

• ADF table with checkbox refresh data binding problem

  Hello.
  
  I use JDeveloper 11.1.1.3. I need to use the table with checkboxes in each row of the table in my project. I use VO with transitional 'Selected' attribute that has a boolean type.
  Everything works well, wait one thing:
  When you click checbox with valueChangeListener and try to get the selected line in the managedBean you won't get any selected lines. After selecting second maaged bean evil shows that 1 single line is selected. It's my managedBean method:
  
  public void SelectCountyClick (ValueChangeEvent valueChangeEvent) {}
  
  DCIteratorBinding it = ADFUtils.findIterator (ITERATOR_NAME);
  
  int selectedRowCount = 0;
  RowSetIterator laughs = it.getRowSetIterator ();
  Line r = rit.first ();
  If (r! = null) {}
  If ((Boolean) r.getAttribute ("Selected"))
  selectedRowCount ++;
  }
  
  While (rit.hasNext ()) {}
  r = rit.next ();
  If ((Boolean) r.getAttribute ("Selected"))
  selectedRowCount ++;
  }
  
  System.out.println ("selected all THE LINES:" + selectedRowCount);
  
  
  }
  
  I tried to change this event to the client event, I got the line number, I put 'true' or 'false' to the code data binding, but whenever I can't correct data after the value change event.
  
  Please help me.
  
  The latest idea is updated databing after click of checkbox, I think. Please help me.
  
  Thank you!

  You must go through the concepts of life cycle of page ADF. In simple terms the Boolean value in the model is not defined in valueChangeListener. Try adding (.processUpdates) valueChangeEvent.getComponent (FacesContext.getCurrentInstance ()); on top of your listener method and see the effect.

• Data binding for Idiots (myself)

  Hey everybody,

  I was asked to create a form that is much more complex than anything I've done in the past. I just wanted to ask a few questions to the experts here before I'm begins, to make sure that I don't make any huge mistakes.

  The complexity of the form lies in the multiplicity of repetitive nested subforms, the fact that it is three forms (which projected form depends on a selection in a drop-down list), and the fact that the form must be designed to export its data such as xml.

  The extent of the building, the form will, I'm comfortable with everything except for export in XML format. I've done a few times, but I'm not sure that the assumptions I made are correct. I tried to read the help files, but I'm not sure I want to come.

  Roughly, I use a ton of subforms to ensure that the layout of the form works dynamically. I don't want all these subforms is displayed in the xml import. The way I do it is to affect the data binding on the subforms "No data binding." Does have an impact on the way that data is stored in the form? If I don't want the value of a field to export, I can put it is linked to "no data binding", or this issue will prevent the values being recorded?

  My last question concerns the link "Use name". So far, in forms I made so that all fields have different names. This form is so large and has so many similar elements, it would be useful to resue field names in different areas of the form. For example, two versions of the forms has a section for the associated addresses. The fields in these sections are the same. I can name them the same thing, as long as they are in different subforms? Or it will cause a conflict when the export/backup.

  Sorry for the long post. In short:

  (1) what the "no data binding" binding afftect data have on subforms and fields, regarding the data saved and exported data? Is there any 'traps!"that I should be aware of?

  (2) what are the guidelines I should follow to make sure that I do not come across all naming conflicts? I just need brother fields are not named the same, or all names are separate?

  I'd appreciate any help that you guys might be able to offer.

  -Scott

  Scott,

  (1) no mandatory date refers to a form object is not included in the exported XML file. Data binding has no effect during the recording of data when you save a form, the form contains the data.

  (2) for me, the #1 rule is use a schema and a schema binding. It is worth the initial investment in time. What you see in the diagram, this is what you see in the output data, given the form object is bound to the schema. You can link an element of single to multiple form objects schema if you need to re - use data through forms, too. Rule #2, for me, is to explicitly set the names sub-shape to simplify the schema binding and to avoid name collisions.

  I have attached a very simple form (with the built-in schema), schema, and the exported xml file to show.

• Data binding does not seem to work

  I have a report with 3 queries - a mother and two children. (In fact, there are more than 2 children, but only 2 of them are at the origin of the problem.) The current version of the report uses frames/repetition, overlapping frames and fields for each request of the child, which makes it almost impossible to change - and I need to change.
  
  I wrote a query that joins the two children in a single request. It works in SQL * more when I add the where clause that expected be added by data - links, but when I run the report I get the same results as when I run it in SQL * Plus without the data where a clause link. So it seems data links do not work for this game of parent/child of queries.
  
  No idea why? (Reports 6i)
  
  It is certain that data binding is the problem. I did the new 'child' an independent query, adding where clause to the query and deletion of data links between the parent and the child, and that is work - at least for the case where the parent returns a single record. I really need that data links work well, then re - asks the child for each parent. On the other hand, report editor showed a strange icon on the request of the child. It seemed to me the icon of data link with a slash through it--and he disappeared when I deleted the data bindings, so I'm sure that the icon showed that data links were not working. He didn't explain why.

• "Data binding will be not able to detect the transfer..." "while [bindable] is set.

  Hello world

  Thank you for taking some time to try to help me.

  I get the warning "data binding will not be able to detect the assignment... "for a

  Collection ArrayCollection all [bindable] properties are set correctly - at least I think... ;-)

  [bindable]
  private var allParties:ArrayCollection = new ArrayCollection();
  

  and then, later:

                 <s:DropDownList id="dropDownList_party_sprecher1"
                                                          [...]
                                     labelField="_internal_partyname">
                      <s:AsyncListView list="{allParties}"/>
                 </s:DropDownList>
  

  The elements of the array collections are a custom class to the mine, which has been automatically

  generated by the php flash builder Gizmo service. This class is also marked as [bindable]:

  [Bindable]
  public class Parties extends _Super_Parties
  {
       [...]
  }
  

  and the extended with class

  [Managed]
  [ExcludeClass]
  public class _Super_Parties extends flash.events.EventDispatcher implements com.adobe.fiber.valueobjects.IValueObject
  {
  [...]
  
       [Bindable(event="propertyChange")] 
      public function get idx() : int    
      {
              return _internal_idx;
      }    
       [Bindable(event="propertyChange")]
      public function get partyname() : String    
      {
              return _internal_partyname;
      }  
  [...]
  }
  
  As I understand it, the [Managed] makes the whole class 
  [bindable] as well and the getters are marked too.
  I've put the [bindable] keyword anywhere I could imagine 
  but it doesn't help at all.
  In principle I wouldn't mind the warning, but the 
  dropdown-list doesn't work.
  
  Please let me know if you need any more information,
  
  Thanks

• A question about data binding

  Hi all

  Data binding is easy to use during development. I often set new directive public property, but I find that I can't control the treatment when the property value changes. I learned that there is a propertyChange event when the property is bindable. If a property is set at 29, and I want to be bordered to 30 in the background. How can I achieve this?

  Thank you

  Hi yancaoshi.  I don't know if I understand the question, so if I miss just let me know.

  You can change the value of a property is the value when set using get/set functions.

  private var _value:Number = 0;

  [Bindable]

  public void value(v: Number): void

  {

  _Value = v;

  }

  public function value(): number

  {

  return _value;

  }

  A regular get/set the installer looks something like the code above.  It creates a property named 'value' that can be accessed as if it was declared as a public var.  The difference is that you can add logic to the set function.

  [Bindable]

  public void value (v: Number): void

  {

  stupid logic to raise 29 and 30

  If (v == 29) {}

  _Value = 30

  } else {}

  _Value = v;

  }

  }

  Now, when someone calls the following code, the value of the 'value' property is actually on 30 and anyone "linked" to this property will get the value 30.

  The following documents may be useful:

• How to fix this bug in data binding?

  Hi all

  I need a mutual-except component as ToggleButton behaves. There is a public property viewMode, which indicates which button is selected. It works fine when I click on other buttons. But when I click the button selected again, it seems that the link does not work.

  The project file is attached. Please help me to fix this problem.

  Thank you and best regards,

  Try adjusting the rocker to false.  Data binding does the right thing, but because you have to toggle the value true, the button is activating / disabling selected after data binding has done his thing.  Try looking at Button.setSelected () to see what I mean.

• refresh of data binding problem

  Hello

  I am a beginner in Flex, and I have a problem with data binding. I have this little program:

  -J' I spend 2 panels ('A' button).

  -When I go to the panel1 to panel2 (click on event), I change the variable 'value' for 'test' (with data binding, Text2 is updated).

  -After this, I manually change the value in Text2 (for example "valeur123").

  -J' I spend panel2 to panel1 (button 'B')

  -J' I go once more of the panel1 to panel2 ('A' button)

  So why the data binding does not work in this case?

  Thank you for your help.

• What is data binding

  Sorry for wasting your time to ask such a simple question. But I'm new to this language and don't understand either terminology of advanced programming.
  
  Can someone explain to me what data binding means. I see this tag in mxml scripts but do not really understand.
  
  I tried to read the documentation from adobe, but it seemed to complex for me.

  Basically, I think, it will simply update items that are related to what the thing said [Bindable] is changed.

  How could a routine walk-run? Inside, Indoor walk or another run? I do this routine outdoors with Gps first so that I'm not kidding my calibration data? Help please and thank you!

  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.

• How to use the data binding on a cluster?

  Hello

  I just discovered the data binding and used it on some primitive controls/indicators. I love the cleanliness of the approach (no additional querying and son required!)

  Now, this page gives to think I can link a cluster with a shared too variable. However, when I right click-> properties, I see that the tabs appearance and Documentation (and I know that I did not accidentally choose an element inside the cluster, because (1) there is a typedef strict, and said the title of (2) 'The Cluster Properties' dialog box). Where can I find the data binding tab?

  Thank you

  Hi JKSH,

  What you're doing is possible if you make the file .ctl as the definition of type rather than a strict definition of type. With a strict definition of type all instances of the same .ctl file link that is why you cannot use data binding.
