How to bind a complex object to a composite component

I'm using JSF2 and having an issue binding an object (EL Expression) as a parameter to my composite component.
I have written a composite component (not very complex) that will display a drop-down list of countries and should bind the selection to a provided target bean.

<h:message id="country-list-error" for="country-list" style="color:red"/>
</a4j:outputPanel>
</h:panelGrid>
</h:panelGrid>
</composite:implementation>
</html>
I want to be able to use the composite component in the following way:
<util:country-select
label="#{msgs['label.countryOfBirth']}"
requiredMessge="#{msgs['error.birthCountryRequired']}"
target="#{participant.countryOfBirth}"/>
When I load the page everything renders correctly, but when I select an item from the drop-down I get a validation error.
apply-form:j_idt77:country-list: Validation Error: Value is not valid
I know that it must be something with the way that I have the parameters defined but I simply can't find any information to help me figure this out.
Any light that you might be able to she on this would be greatly appreciated.
Thank you for the help...

Hi,
well, you can. What the ADF Data Control and thus the binding gives you is the JSF component binding and the business service access.
If you don't want to use ADF, then what you can do is
- Create an ADF BC root Application Module from a managed bean
e.g. see http://docs.oracle.com/cd/E21764_01/web.1111/b31974/bcservices.htm#CHDDDBFC
- Access the View Object for querying the data to display
- Expose the queried data so the component can handle it e.g. setter/getter for input components, ArrayList for tables (or you create the more complex component models like table and tree models)
Having outlined the above, here are some gotchas to watch out for
- Make sure creating the root application module is done such that you don't create/release it with each request. So you may consider a data serving managed bean in a scope like page flow or session
- Ensure you have helper methods that allow you to query and CRUD operate the View Object data

How to bind "Image Field" object on a database

Hi to all
I inserted into a dynamic PDF (Livecycle ES3 trial) an image field, but I don't understand how I can to bind a JPG into a database.
In (F5) preview... I'm able to open a image file on filesystem and visualize it on PDF form... but then? How to bind on database?
In my several tentatives I'm using a MS Access 2010 database table, where I defined a OLE object... but doesn't work.
Thank you at all.

Creating a new cell factory, how to bind to my object's property

As near as I can tell, the javafx binding using observable values, alot like jgoodies and its not like SWT databinding or WPF binding.
I was creating a cell factory for a TreeView. Just using a label to display the contents and calling toString, alot like the way it works now. However, I could not figure out to create a binding that would bind to a property on my domain object. Is there a way to specify the binding to the Label's text property so that whatever object that the cell's item's value has I can bind to a property that I specify on it e.g. the "name" property. But I could not see how to do that. Also, the only way I could figure out how to update the Label's value was from updateItem. I thought maybe I could even setup the binding in updateItem so that when the TreeItem's value changed at least it would automatically update the label binding, but the API did not seem to support that.
What's the right coding pattern to use when using straight Java coding?
I know in jgoodies I could do this using the PresentationModel approach or master-detail SWT or WPF with just specifying the property on the item's property that I want in WPF.
public static class MyTreeCell extends TreeCell<Object> {
 Label label;
 public MyTreeCell() {
 label = new Label();
 setNode(label);
 @Override
 public void updateItem(TreeItem<Object> arg0, boolean arg1) {
 if (arg0 != null && arg0.getValue() != null) {
 System.out.println("New value: " + arg0.getValue());
 label.setText(arg0.getValue().toString());
 } else {
 System.out.println("New value is null and this println is called alot, why is that?");
 super.updateItem(arg0, arg1);
 }

Well the presentation model thing worked fine and I have some machinery for the cell factory/cell item to obtain a tree cell based on the domain object type (a template/factory is placed into the properties in the scenegraph hierarchy). But its not smooth yet and the pattern does not quite translate well into javafx. Because the cell factory produces cells that could be used for a variety of domain object types, all the logic gets pushed down to the treecell subclass which makes it messy. Maybe this is where CSS selectors need to come in, you specify the class of a tree cell for a specific domain object type and you can set that at the root of the application so it cascades. I'll see if this approach works.
Here's the code for the javafx version of jgoodies' presentation model, less the corner cases. This allows you to bind to a property and change the bean underneath that the property accesses. I'm not convinced that having properties has observable values directly on the objects is the right model for javafx because of the coupling to the actual object the property represents. Sometimes, you need to represent the property concept separate from the actual object instance. Maybe this already exists in the library.

How to bind a String object to java:comp/env name space?

Hi, does anybody know how to declare a String as a JNDI object in OC4J V904. I want to register a String named 'Foo' with the value 'val' with JNDI. Eventually I want to get the value of this by referencing this JNDI name:
java:comp/env/ejb/Foo
I don't really care how this is done either by declaring it by way of ejb-jar.xml or a global setting at the application server level.
Please assist!
Thanks
J

There are many possible ways.
- (BEST) Use the J2EE resource environment variable mechanism (ie resource-env-ref in ejb-jar.xml).
- (MEDIUM) Use OC4J startup classes.
- (IF ELSE FAILS) Use the InitialContext.rebind method.

How to bind Hibernate domain objects to the UI layer

Dear All,
I am trying to bind FX UI controls to properties of a Hibernate Domain object. Is there any good example to refer to for this purpose?
Thanks & Regards,
Nitin Gupta

Assuming you do not formulate your hibernate objects as pojos with javafx properties directly, if the hibernate object is a pojo with or without PCL, you can convert the properties of the pojo to observable values (or properties) directly. These are used in a bind statement.
Check out what jgoodies does with BeanAdapter or PresentationModel. You need the same concept. I've attached a class that does this for a pojo already (its an incomplete port of jgoodies PresentationModel). It will work for any pojo. It does not have setter support as it was just a demonstration. Its efficient for a pojo with a large number of properties. You could also write a very short property connector to produce one observable value per property. The value of the class below is to be able to swap out the bean being observed without having to change or reset the property observable values each time. Bind once and then just reset the bean (think master detail).

* An object binding object that creates object bindings based on property names

* values directly dependent on the underlying bean. The actual bean the

* the bean to bind to or the bean to bind to will change as in the detail part
* of a master-detail screen. Generally, the return values from
* <code>getProperty()</code> should be used for binding not the factory itself.
* The object should be a domain object bean with bean methods to get or set the
* value using java bean naming conventions OR it should use javafx property
* definition conventions. The factory will automatically listen for standard
* java bean changes using <code>PropertyChangeListener</code> approaches unless
* you indicate to not to.
* 
* When the bean itself changes, the properties fire to indicate that their

How to bind complex input/output types in web service data control

Hi,
I have created data control using external web service for simple input & output data type and its working fine.
But I don't know how it can be done for complex data types.
My external Web services have complex input & output types. Such as java object which contains another java object again it contains another java object or arry or java collection etc.
Each my service has one complex input data type and for this no user input is require so how I can do it without using any component for it.
I want to bind my page components with this input & output type.
What is the best approach to do this and how to bind screen component.

How to convert an array collection instance to a complex object for interaction with webservice

Hi there,
I have a stubborn problem that I am trying to work out the best way to solve the problem. I am interacting with a WebService via HTTPService calling a method called find(String name) and this returns me a List of ComplexObjects that contain general string and int params and also lists of other Complex Objects. Now using the code:
ArrayCollection newOriginalResultsArray = new ArrayCollection(event.result as Array)
flex converts my complex objects results to an arraycollection so that I can use it in datagrids etc. Now up until this part is all good. My problem is when getting a single instance from the results list, updating it by moving data around in a new datagrid for example - I want to interact with the webservice again to do an create/update. This is where I am having problems - because these webservice methods require the complex object as a parameter - I am struggling to understand how I can convert the array collection instance back to my complex object without iterating over it and casting it back (maybe this is the only way - but I am hoping not).
I am hoping that there is a simple solution that I am missing and that there is some smart cookie out there that could provide me with an answer - or at least somewhere to start looking. I guess if I have no other alternative - maybe I need to get the people who built the service to change it to accept an array - and let them do the conversion.
Any help would be greatly appreciated.
Bert

Hi Bert,
According to my knowledge you can use describeType(Object) method which will return an XML... That XML will contain Properties and values just iterate through the XML and create a new Object.. Probably u can use this method...
public function getObject(reqObj:Object,obj:Object,instanceName:String,name:String=null,index:int=-1):Obj ect
 if(!reqObj)
 reqObj = new Object();
 var classInfo:XML = describeType(obj);
 var className:String = instanceName;
 if(name!=null)
 className=name+"."+className;
 if(index!=-1)
 className=className+"["+index+"]";
 for each (var v:XML in classInfo..accessor)
 var attributeName:String=v.@name;
 var value:* = obj[attributeName]
 var type:String = v.@type;
 if(!value)
 reqObj[className+"."+attributeName] = value;
 else if(type == "mx.collections::ArrayCollection")
 for(var i:int=0;i<value.length;i++)
 var temp:Object=value.getItemAt(i);
 getReqObject(reqObj,temp,attributeName,className,i);
 else if(type == "String" || type == "Number" || type == "int" || type == "Boolean")
 reqObj[ className+"."+attributeName] = value;
 else if (type == "Object")
 for (var p:String in value)
 reqObj[ className+"."+attributeName+"."+p] = value[p];
 else
 getReqObject(reqObj,value,attributeName,className);
 return reqObj;
Thanks,

How to bind schema form data to existing objects?

I imported an existing PDF as my template and it make all the text, check boxes and text fields into objects - Great!
But now when I add a schema with my DB data field names I am unsure how to turn the existing objects on the form to the schema fields!!
Can anyone help?

Open the DataView where your schema is visually represented and simply drag and drop the schema item onto the object that you want to bind it to. If the bind is successful a little icon will appear in the DataView beside the node.
If you select on object in the form and click on the Binding tab, you will see an expression representing what you are bound to. You can also use the icon there to navigate to the appropriate node in the schema.

How to bind Link Details Button to an object?

Each object has a unique id associated to it. One can retrieve that id string from an object by calling the toString() method, as long as this method hasn't been overridden from its default behavior.and if it has System has a method to help you.
But it is not quite a unique id. It might be, but a different JVM could implemented it as "return 1" and it would still technically satisfy the contract.
As much as is reasonably practical, the hashCode method defined by class Object does return distinct integers for distinct objects. (This is typically implemented by converting the internal address of the object into an integer, but this implementation technique is not required by the JavaTM programming language.)

how to bind bar chart(columns) to array list object in c#win form

Hi Ramesh,
Did you want to bind list object to bar chart? I made a simple code to achieve binding list to bar chart.
public partial class Form0210 : Form
public Form0210()
InitializeComponent();
private void Form0210_Load(object sender, EventArgs e)
BindData();
public void BindData()
List<int> yValues = new List<int>(new int[] { 20, 30, 10, 90, 50 });
List<string> xValues = new List<string>(new string[] { "1:00", "2:00", "3:00", "4:00", "5:00" });
chart1.Series[0].Points.DataBindXY(xValues, yValues);

How to bind a user selected value to a view object bind variable?

Hi
I have two pages in ADF BC application. In the first page ,i will give a drop down menu to user which displays all the table names in my databse.
when the user selects a table and goes to the second page..he should be given a menu or a check list of all the columns in the user selected table....
to display the columns i have used the query
Select COLUMN_NAME from user_tab_columns where table_name = : table_name in the view object.
now how to bind the user selected table value in the first page to the table_name bind variable in view object ?
thanks
swathi.

Hi,
depends on how the select box is implemented. With ADF and ADF Faces, the default value selection is the list index. In a value change listener you could look up the selected value from the underlying iterator. Store this value e.g. in a session attribute and point the NDValue of the ExecuteWithParams operation to #{sessionScope.your_attribute}

To bind an object into the JNDI tree check the documentation here:
http://e-docs.bea.com/wls/docs81/jndi/jndi.html#475702
If this is to be used by all your applications that you deploy on the server check out the startup/shutdown class documentation here:

How to bind list data to XML Web service request

How do I bind specific columns in a DataGrid to the Web
service request? I'm having trouble finding any documentation that
addresses that specific pattern, i.e. sending a complex list to the
server via a Flex Web service send() command. I'm fairly new to
Flex programming and don't know if what I want to do is possible.
Here what I've been able to do so far.
1. Using a Web service called a service on the server and
retrieved a complex list.
2. Poplulated a DataGrid with the result
3. The user has selected multiple rows from the DataGrid
using a checkbox column
4. The user pressed a button that calls a Web service send().
This Web service should only send data from only two columns and
only for those rows the user has checked.
5. I can loop over the DataGrid and find the selected rows
and put them in another ArrayCollection called 'selectedRows'.
The issue is that I don't know how to bind 'selectedRows' to
the Web service. Right now I'm reading up on "Working with XML" in
the Programming with ActionScript 3.0 chapter. But I'm just fishing
here. No bites yet.

Don't bind. Build the request object programatically, as you
are doing with your selectedRows AC, and send(myObject) that.

How to Bind a Combo Box so that it retrieves and display content corresponding to the Id in a link table and populates itself with the data in the main table?

I am developing a desktop application in Wpf using MVVM and Entity Frameworks. I have the following tables:
1. Party (PartyId, Name)
2. Case (CaseId, CaseNo)
3. Petitioner (CaseId, PartyId) ............. Link Table
I am completely new to .Net and to begin with I download Microsoft's sample application and
following the pattern I have been successful in creating several tabs. The problem started only when I wanted to implement many-to-many relationship. The sample application has not covered the scenario where there can be a any-to-many relationship. However
with the help of MSDN forum I came to know about a link table and managed to solve entity framework issues pertaining to many-to-many relationship. Here is the screenshot of my application to show you what I have achieved so far.
And now the problem I want the forum to address is how to bind a combo box so that it retrieves Party.Name for the corresponding PartyId in the Link Table and also I want to populate it with Party.Name so that
users can choose one from the dropdown list to add or edit the petitioner.

Hello Barry,
Thanks a lot for responding to my query. As I am completely new to .Net and following the pattern of Microsoft's Employee Tracker sample it seems difficult to clearly understand the concept and implement it in a scenario which is different than what is in
the sample available at the link you supplied.
To get the idea of the thing here is my code behind of a view vBoxPetitioner:
<UserControl x:Class="CCIS.View.Case.vBoxPetitioner"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
xmlns:v="clr-namespace:CCIS.View.Case"
xmlns:vm="clr-namespace:CCIS.ViewModel.Case"
mc:Ignorable="d"
d:DesignWidth="300"
d:DesignHeight="200">
<UserControl.Resources>
<DataTemplate DataType="{x:Type vm:vmPetitioner}">
<v:vPetitioner Margin="0,2,0,0" />
</DataTemplate>
</UserControl.Resources>
<Grid>
<HeaderedContentControl>
<HeaderedContentControl.Header>
<StackPanel Orientation="Horizontal" HorizontalAlignment="Right">
<TextBlock Margin="2">
<Hyperlink Command="{Binding Path=AddPetitionerCommand}">Add Petitioner</Hyperlink>
| <Hyperlink Command="{Binding Path=DeletePetitionerCommand}">Delete</Hyperlink>
</TextBlock>
</StackPanel>
</HeaderedContentControl.Header>
<ListBox BorderThickness="0" SelectedItem="{Binding Path=CurrentPetitioner, Mode=TwoWay}" ItemsSource="{Binding Path=tblParties}" />
</HeaderedContentControl>
</Grid>
</UserControl>
This part is working fine as it loads another view that is vPetioner perfectly in the manner I want it to be.
Here is the code of vmPetitioner, a ViewModel:
Imports Microsoft.VisualBasic
Imports System.Collections.ObjectModel
Imports System
Imports CCIS.Model.Party
Namespace CCIS.ViewModel.Case
''' <summary>
''' ViewModel of an individual Email
''' </summary>
Public Class vmPetitioner
Inherits vmParty
''' <summary>
''' The Email object backing this ViewModel
''' </summary>
Private petitioner As tblParty
''' <summary>
''' Initializes a new instance of the EmailViewModel class.
''' </summary>
''' <param name="detail">The underlying Email this ViewModel is to be based on</param>
Public Sub New(ByVal detail As tblParty)
If detail Is Nothing Then
Throw New ArgumentNullException("detail")
End If
Me.petitioner = detail
End Sub
''' <summary>
''' Gets the underlying Email this ViewModel is based on
''' </summary>
Public Overrides ReadOnly Property Model() As tblParty
Get
Return Me.petitioner
End Get
End Property
''' <summary>
''' Gets or sets the actual email address
''' </summary>
Public Property fldPartyId() As String
Get
Return Me.petitioner.fldPartyId
End Get
Set(ByVal value As String)
Me.petitioner.fldPartyId = value
Me.OnPropertyChanged("fldPartyId")
End Set
End Property
End Class
End Namespace
And below is the ViewMode vmParty which vmPetitioner Inherits:
Imports Microsoft.VisualBasic
Imports System
Imports System.Collections.Generic
Imports CCIS.Model.Case
Imports CCIS.Model.Party
Imports CCIS.ViewModel.Helpers
Namespace CCIS.ViewModel.Case
''' <summary>
''' Common functionality for ViewModels of an individual ContactDetail
''' </summary>
Public MustInherit Class vmParty
Inherits ViewModelBase
''' <summary>
''' Gets the underlying ContactDetail this ViewModel is based on
''' </summary>
Public MustOverride ReadOnly Property Model() As tblParty
'''' <summary>
'''' Gets the underlying ContactDetail this ViewModel is based on
'''' </summary>
'Public MustOverride ReadOnly Property Model() As tblAdvocate
''' <summary>
''' Gets or sets the name of this department
''' </summary>
Public Property fldName() As String
Get
Return Me.Model.fldName
End Get
Set(ByVal value As String)
Me.Model.fldName = value
Me.OnPropertyChanged("fldName")
End Set
End Property
''' <summary>
''' Constructs a view model to represent the supplied ContactDetail
''' </summary>
''' <param name="detail">The detail to build a ViewModel for</param>
''' <returns>The constructed ViewModel, null if one can't be built</returns>
Public Shared Function BuildViewModel(ByVal detail As tblParty) As vmParty
If detail Is Nothing Then
Throw New ArgumentNullException("detail")
End If
Dim e As tblParty = TryCast(detail, tblParty)
If e IsNot Nothing Then
Return New vmPetitioner(e)
End If
Return Nothing
End Function
End Class
End Namespace
And final the code behind of the view vPetitioner:
<UserControl x:Class="CCIS.View.Case.vPetitioner"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
xmlns:vm="clr-namespace:CCIS.ViewModel.Case"
mc:Ignorable="d"
Width="300">
<UserControl.Resources>
<ResourceDictionary Source=".\CompactFormStyles.xaml" />
</UserControl.Resources>
<Grid>
<Border Style="{StaticResource DetailBorder}">
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="Auto" />
<ColumnDefinition Width="*" />
</Grid.ColumnDefinitions>
<TextBlock Grid.Column="0" Text="Petitioner:" />
<ComboBox Grid.Column="1" Width="240" SelectedValuePath="." SelectedItem="{Binding Path=tblParty}" ItemsSource="{Binding Path=PetitionerLookup}" DisplayMemberPath="fldName" />
</Grid>
</Border>
</Grid>
</UserControl>
The problem, presumably, seems to be is that the binding path "PetitionerLookup" of the ItemSource of the Combo box in the view vPetitioner exists in a different ViewModel vmCase which serves as an ObservableCollection for MainViewModel. Therefore,
what I need to Know is how to route the binding path if it exists in a different ViewModel?
Sir, I look forward to your early reply bringing a workable solution to the problem I face.
Warm Regards,
Arun
