Data binding to DataGrid problem

• 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.

• 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);
  	}
  	/**
  	* @inheritDoc
  	*/
  	public void willTrigger(type:String):Boolean
  	{

• 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:

  <? XML version = "1.0" encoding = "utf-8"? >
  " < = xmlns:mx mx:Application ' http://www.Adobe.com/2006/MXML "layout ="absolute"> "
  < mx:Script >
  <! [CDATA]

  < mx:Panel id = "panel1" >
  < mx:TextInput id = "text1" / >

  < / mx:Panel >
  < / mx:ViewStack >
  < / mx:Application >

  -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)

  = > and this time, the "Text2" TextInput is not being updated. the value is not changed (always "valeur123").

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

  Thank you for your help.

• 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.

• Trying to Oracle data BINDING

  This should be very simple, but it gives me a lot of problems. I am return to Oracle data in a datagrid, and then I'm trying to use the BINDING attribute on CFINPUT tag to display the data.

• 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.

  Suggestion of levancho on sends an event seems good to me.

  This could look like this:

  var userEvent:UserEvent = new UserEvent ("new user", newUser);
  dispatchEvent (userEvent);

  Where UserEvent is an event with the new object.
  Then all the elements that need this change pourraient, follow these steps:

  addEventListener ("new user", userChanged);

  private void userChanged(evt:UserEvent):void
  {
  evt. User; Update the link with the new user...
  }

  After looking more on the problem, I found:
  Initially, the main problem was that the variable in the function will not update the refence sent in the function when you create a new instance, regardless of the use of data binding or not...

  Do not use "mx.utils.ArrayUtil.toArray" with XML. It is only for tables that you get with mx: Model.

  Your class and function can be linked? There is no argument on the function, so how is the framework going to know when the connection of fire?

  You do not receive warnings of liaison?

  Use a lableFunction so you can debug the objects of the item in the dataProvider.

• Alignment columnar with DataGrid problem

  Hi all.
  
  I have the following data grid:
  
  http://www.joshbeall.com/personal/Flex/Grid1.PNG
  
  If you filter some of the results with zeros in columns cited/applied, that's what you get:
  
  http://www.joshbeall.com/personal/Flex/Grid2.PNG
  
  See how the column heads are not aligned with the columns? Oddly enough, I still don't understand this behavior, but it often happens. If I click a column head (to change the sort order), the alignment is corrected.
  
  I have attached the full MXML for this application.
  
  BTW, another problem, I had (and have given up trying to hunt down is), why should I declare my WebService as < mx:WebService >, instead of simply do entirely in code? You can see in my MXML that I put in the comment a few lines of AS the initialization of the instance of WebService. I was originally, declaring and using my WebService entirely in code. However, data binding didn't work - the grid never filled. When I changed it to be declared as a < mx:WebService > tag, everything started working.

  Peter, I caught SDK build 180310/Wed Aug 22 2007 and that fixed the display problem.

  Rvollmar, thanks for the tip on [Bindable]. Add this attribute corrected the problem. You call the 'attributes' in ActionScript? 'attribute' is the name of .NET.

• &amp; quot; data binding will not be able to detect assignments &amp; quot; warning

  new features in Flex Builder 3, Beta 2 (I did not have this problem with Beta 1), I have randomly (it seems) get warnings "data binding will not be able to detect assignments to < property >" for properties that are Bindable. If I run my AIR application while I have these warnings the app will not be able to detect assignments to these properties, as warning says. However do a rebuild/clean removes these warnings and my app then works well, with data binding works as expected. I have not found a way to force this behavior, it seems just occur occasionally during development.
  
  others have this problem?
