Subform with data binding that repeats

Similar Questions

• Problem with data rawValue is repeated

  The value in quotes get repeated twice. Any idea?

  If (this.rawvalue! = null) {}

  this.rawValue = "/" + this.rawValue;

  }

  Desired result = / SampleData.

  Obtained result = / / Sample Data. Gets "/" repeated twice.

  To test against the null value, you must use the operator! == instead of! =

  If (this.rawValue! == null) {}

  this.rawValue = "/" + this.rawValue;

  }

  Well, this propably will not avoid the slash repeats because the script will add an extra slash every time it is drawn.

  You will need to check the current value of a forward slash at the beginning by using a regular expression:

  /^\//g

  The script him were like as:

  If (this.rawValue! == null) {}

  If (! this.rawValue.match(/^\//g)) {}

  this.rawValue = "/" + this.rawValue;

  }

  }

• Is it possible to access control with data binding to the page

  Hello
  
  I want to know if we can access the datacontrol operations in the bean with managed to link these operations to the definition of the page.
  
  For example: I have a method in the application Module that is under the control of data and create an impression of the page with link of this operation to the definition of the page.
  I created a button on the page and when you click on the button it calls a method in the managed bean.
  Can I run the operation in the data from the managed bean code control? Can I handle for the data from the managed bean code control?
  
  Please let me know if this can be done or not.
  
  Thank you
  Stephanie

  Why you don't want to use binding for this? Is there a specific reason for it, or you want to just make life harder?
  You could write a managed bean that has a method that creates and instance of AOS and calls the method - and then just call managed method from your page bean.

• 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.

• 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 >

  < / 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.

  Yes you were not trying to bind your data to 2 channels, but I said that because assumes that if you have two way data binding support now, so know you only problem.consider the following two lines, which run two way data binding

• Outerjoin in data binding?

  Hello
  I have a report that uses two queries with data links in the data model. I wish that requests to join as an outerjoin. It is if there is no trace in the query in detail then also the lines must be returned. Please tell us how I can do this.
  
  Thank you

  I don't think that you can do with data binding in groups. It is best to merge this request in detail in the main query and
  use outer join it and create groups as the group above report.

• &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.

• 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.

• The research of Web applications with fields of the Data Source that contains multiple values

  I have a Web application with a field that allows multiple values to be recorded similar to the list box. I need limit the allowed values for a large, over the list of the values currently stored in another Web application as a data source. I can not apply to the type of Data Source field that allows only single value selection. I also need to be able to use the search form Web App to search for items containing 1 OR more of the values in this field (a type of list control field search functionality). Here's what I tried to field types:

  • Text (String) or text (multi-line) field type - By saving a list of values separated by commas (outputs in the same way this list box) to an entry of text or textarea, the search only logic search exact string (including commas) and does not analyze individual values.
  • Type of list (checkbox) field - it allows me to search for multiple values using the logic of the GOLD, but the web application stores only the values that have been entered as an option in the field settings real web app. I tried to use a checkbox with minimal or empty options list, hoping that some values I sent more separate by a comma value chain would be still stored, but because the values come from my Web App data source and not stored with the field options list, they were not saved.

  Someone at - he found a way to do it?

  My other question is how can I use a multivalued field to similar as described above but return results containing the elements with ALL the values of this field (AND logic).

  Can someone enlighten me to the inner workings of the search BC logic web app?

  You don't need to use the predefined boxes or types of entries. Everything you can represent as a string (such as the values separated by commas in your example) can be saved in any field of webapp. The types of fields defined in the Web application are only used to translate internal representation (all channels) to the various user-friendly interpretations (checkboxes, radios, dates, links, etc.)

• 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,.

  Pete

  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
  	{
  		Return _bindingEventDispatcher.willTrigger (type);
  	}

• How to create a subform with several rows initialized?

  I have a repeating subform on my form that should start with several lines initialized.

  I can create several blank lines by setting the binding "repeat subform for each data element" and set the number of 'min', but I would like to have values in one of the columns so that doesn't happen.

  I can create multiple instances of my subform named and initialize the value of the column in question, but then if I have the "repeat subform for each data item" checked I get additional dups, but the first row and the button Delete (right-click action "this.parent.instanceManager.removeInstance (this.parent.index);" ')»» and Add button (click an action "_rates.addInstance (1)" "") erratic behavior.  I mean here the button Add adds sometimes lines with values that have been deleted previously, and the delete button sometimes a warning saying something like "topmostSubform [0]: Page1 [0]: rates [10]: delete_button [0] .click on Index value is out of range.

  There is no connection to a data source where I could get the values for the column, I want to initialize.  In my opinion, I'm close, if only I could find the correct settings for the links palette.

  Thanks for your suggestions!

  If you have columns and rows, why not use a table instead of subform...

  Check the setting of binding to "repeat the line for each data item.

  Add the button 'Delete Row' to each line in the last column.

  Add the button 'Add Row' under the Table.

  Add text fields to the columns that you want the data displayed / modified by the user.

  I hope this helps.

  If not, let me know...

  Thank you

• About the data binding object

  I've set up a Repeater to display XML data. A single field, called rsvpStatus, is a Boolean value, returning as Y or N. I'd rather see something like YES or no. so I thought I could put in place the following text box:
  
  < mx:Text text="{Constants.yesNoTranslator[data.rsvpStatus]}"/ >
  
  and also to set up an associative array reflecting O/N YES/no such as:
  
  [Bindable]
  public static var yesNoTranslator:Object = {N: 'No', Y: 'Yes'};
  
  I'm being warned by Flex Builder that:
  "Data binding will not be able to detect changes when using square brackets operator. For array, use ArrayCollection.getItemAt (). »
  
  Despite this warning, it seems to work.
  
  My question is:
  I've set up with this warning and assume it is useless, or is there a good reason to change the structure of my code?
  
  See you soon
  Craig

  Thanks good for this Sreenivas I'm much clearer about all this now.
  all this got me thinking - it would make sense to create a new class, say "ObjectCollection' ObjectProxy extension with a"getItemAt"method to facilitate the fixation on objects in situations such as these:
  (my apologies but no button code to join for some strange reason)

  
  http://www.Adobe.com/2006/mxml">
  
  
  [Bindable]
  public var yesNoTranslator:ObjectCollection = new ObjectCollection({Y:"Yes",N:"No"});)
  [Bindable]
  public var rsvpStatus:String = 'Y ';
  ]]>
  
  

  package
  {
  Import mx.utils.ObjectProxy;

  SerializableAttribute public class ObjectCollection extends ObjectProxy
  {
  public void ObjectCollection (point: Object = null, uid:String = null, proxyDepth:int = - 1).
  {
  Super (item, uid, proxyDepth);
  }
  [Bindable (= "propertyChange" event)]
  public void getItemAt(index:String):Object {}
  Return (this [index]);
  }

• 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.

• data binding single graphic multiple graphic xpf in curves

  I am to evaluate MS2013 in VS2012.  I have a long history with MS and Visual C++.  My goal is to trace frequency vs. voltage data from two channels of dac.  I collect data at a particular frequency for both channels, process the data and then plot two points xy resulting.  As indicated in the messages earlier I found examples of bind a data set unique xy via an array of points connected with. Source of data but not a way to bind to multiple locations.  I tried without success to find a ChartCollection who would treat a double clue and two values double y.

  A stated differently, I would link two chart XY plots in one NOR: Graph of unique to a data source wpf I can fill over time and I am the Microsoft graph chart throughout the period.

  My apologies if I missed an element of documentation that addresses this requirement.

  Unfortunately, we do not have predefined data types that will draw more than one value of Y against a single value X. Using a ObservableCollection<Point[]> is a valid approach.

  If you draw (X-values are always growing), you can use a table of ChartCollection instead and imitate a picture to multiple values by using an extension method:

  public static class ChartExtensions {

  public static void Append( this ChartCollection[] charts, double x, params double[] ys ) {
            for( int i = 0; i < ys.Length; ++i ) {
                double y = ys[i];
                var chart = charts[i];
                chart.Append( x, y );
            }
        }

• Data binding occurs after onAdded() in CellRenderer?

  Hi all, I extend the qnx.ui.listClasses.CellRenderer for my TileList. I noticed that sometimes the this.data would be null in my overridden onAdded() function.

  After some tests, I realized that if I use a timer to check this.data seconds later, it would be filled with the correct data, it seems that the data binding happens a moment after the onAdded() function is called.

  I'm happy to rely on the timer to the time delay, but someone has a better solution? Is there something else I should listen to instead of according to onAdded()?

  Hey,.

  This kind of thing makes me forget all sleep haha clearly that I don't SLEEP much at all!

  OK, so I think I got the fix for this. instead of simply relying on onAdded() method that we must look in the drawLabel() method. in the contstructor this time, we do the new CheckBox object where our customization starts later with so we don't have duplicates of this object that is created each time the drawLabel method is called. instead of making the bulk of the work in the onAdded method, we will just to remove the object from the label that is displayed via the cell rendering engine. After that when the drawLabel() method is called, which is when we do our customization. mine includes a checkbox just to test. then we finally remove our object as usual in the onRemoved() method.

  Here's the code for update for the rendering engine:

  package
  {
      import flash.events.Event;
      import flash.events.MouseEvent;
