Binding to an indexed property
Hi
Not sure if this is the correct way to do this, but I created
an indexed property ( String array ) in the session bean
with the intention of binding a TextField value to an
indexed position on the indexed property. When attempting
to perform the Property Binding for the TextField component
I don't see the indexed property to bind to.
Is this possible ?
Thanks

System generated index property not generated in database
Hi,
I created an offline table by copying it from an (first) online database to my project. The table contains a unique key constraint, which references a system generated index. Now I used this offline table to generate a table in another (second) online database. This all works well except, that the "System Generated" property of the index is "false" and not "true" as in the offline table (and the first online database). When I manually reconcile the same table to the second online database again, there is always a difference shown for this index property. When I try to continue the reconcile process to change this property I get an error message, that the index cannot be dropped because it is obviousely referenced by the unique constraint.
When I drop the constraint and try to generate the index only I get the following warning message:
Jan 11, 2012 2:08:59 PM oracle.javatools.db.property.AbstractPropertyManager processDiffs
WARNING: Unsupported property: systemGenerated
Is there a way to work around this annoying behavour? Is it possible to change this index property by an ALTER INDEX statement?
Im using JDeveloper 11.1.2.1.0 (Build JDEVADF_11.1.2.1.0_GENERIC_110907.2314.6081)
Thanks for help and hints

Edited by: thmayr on 11.01.2012 05:08Hi,
it might be due to some BUG in RDBMS...
First Check the Secondary index in TEST system
Look at the Transport Number in DEV system, If this is having error, then it will show you the error details also,
If that not moved Properly then you need to create another request for the INDEX and move it again
See the threads with similar problem...

Indexed property - editor needed?
Folks,
I have a bean (MyBean) with a indexed property (array of class type ClassX). It has setter and getters (total of 4) according to Java Beans specification.
On Netbeans, the indexed property appears on Properties list. But, I can�t add itens to it, like it occurs when the property is not indexed or is a String indexed property. I think I should assign an 'editor' to it.
Does anybody knows how to do this?
The idea is: the ClassX is a JComponent and the Frame has some of them (10, for example). This indexed property from MyBean should allow users to add as many as they want, but limited to those already added to the Frame. They could add, for example, 4 of 10 to the array.
Thanks!Did you try selecting portal components like books, pages, portlets. I have seen this problem too. But it would go away when you restart workshop.

Help with array / indexed property
Hi,
I am trying to save the value of multiple dropdowns in the Session Bean. Therefore, I created an index property "rule" in the Bean.
Each time the page is loadad, a different dropdown appears depending on the previous choices. If the ok button is clicked, the action is performed to save the current dropdown value in the index property:
public String button1_action() {
int cnt = 1;
// if page was loaded before, replace count
if (getAdminBean().getCount() > 0) {
cnt = getAdminBean().getCount() +1;
} else {
// save current count in Session
getAdminBean().setCount(cnt);
setValue("#{AdminBean.rule[cnt-1]}", selectme.getValue());
This is the error message:
Exception Details: javax.faces.el.PropertyNotFoundException
Error setting property '-1' in bean of type null
Possible Source of Error:
Class Name: com.sun.faces.el.PropertyResolverImpl
File Name: PropertyResolverImpl.java
Method Name: setValue
Line Number: 153
I have played around and even the following code would not work to save a value at the first position of the index property:
setValue("#{AdminBean.rule[0]}", selectme.getValue());
Can anyone help?
Thanks,
NilsYou can not set the index as you use here i.e
#{AdminBean.rule[cnt-1]}
is not correct. Because in JSF the "[" is used for some other purpose.
I would suggest you to use another property called "index"
setValue("#{AdminBean.index", cnt-1);
setValue("#{AdminBean.rule", selectme.getValue());
Inside the session bean, in the method setRule get the index (already set) and place your value in the correct indexed array.
Same logic you can use to get the value too
setValue("#{AdminBean.index", cnt-1);
getValue("#{AdminBean.rule");
the method getRule() should get the value for the index and return it.

I have several forms each containing a unique product. Each product has 'other' items that can be associated with each product.
Rather than creating setter and getter methods for each 'other' item (too many to do), I thought I'd send the values of those 'other' items to an indexed property like String[] other. A user will be presented with a list of 10 or so 'other' items for each, and each 'other' item will have a checkbox. I'd like only the checked values to show up on another page.
Is an indexed property the way to go with this? Plus I could iterate through the 'other' list on the seperate page. Any examples anyone knows of I can look at for some help? Thanks!public String button1_action() {
setValue("#{AdminBean.rule[1]}",
selector.getValue());
How about
getAdminBean().setRule(1, selector.getValue());Assuming that selector.getValue() returns a Long and that AdminBean is either an Application, Session, or Request Bean.
Best regards

Is there an example out there for a Java Newby - I am trying to save data in an array - that is using the indexed property in a SessionBean.
I have then added the indexed property and bound the value to it:
* Indexed getter for property rule.
* @param index Index of the property.
* @return Value of the property at <CODE>index</CODE>.
public Long getRule(int index) {
return this.rule[index];
* Indexed setter for property rule.
* @param index Index of the property.
* @param rule New value of the property at <CODE>index</CODE>.
public void setRule(int index, Long rule) {
this.rule[index] = rule;
public String button1_action() {
setValue("#{AdminBean.rule[1]}", selector.getValue());
I am getting the followong error:
Exception Details: org.apache.jasper.JasperException

Binding of a dependency property in a userControl does't work!
public static readonly DependencyProperty myTBProperty =
DependencyProperty.Register("myTB", typeof(decimal?), typeof(TB2), new FrameworkPropertyMetadata() { BindsTwoWayByDefault = true });
public decimal? myTB
get { return (decimal?)GetValue(myTBProperty); }
set { SetValue(myTBProperty, value); }
<TextBox Grid.Column="1" Text="{Binding myTB,Mode=TwoWay}" Width="{Binding TBWidth}"/>
The above code is for a UserControl.
Now I used this UserControl into another UserControl like this:
<c:TB2 myText="OutSide Diameter" myTB="{Binding Di,Mode=TwoWay}" TBWidth="120"/>
private decimal? _Di;
public decimal? Di
get { return _Di; }
set
_Di = value;
NotifyPropertyChanged();
But when I change the Value of Di, nothing happens. I have also tried with an ordinary TextBox and it works.You cannot explicitly set the DataContext of the TB2 UserControl.
Give TB2 a name in the XAML markup:
<UserControl x:Class="WpfApplication1.TB2"
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:local="clr-namespace:WpfApplication22"
mc:Ignorable="d"
d:DesignHeight="300" d:DesignWidth="300" Name="tb2">
...and bind to the myTB property of the UC using the ElementName syntax:
<TextBox Grid.Column="1" Text="{Binding myTB,Mode=TwoWay, ElementName=tb2}" Width="{Binding TBWidth}"/>
Do not set the DataContext of TB2 to itself programmatically because then you cannot bind to the Di source property in the other UC.

How to binding and change VM property value when DataTrigger?
Hi all,
Please see the below code. The current work is when mouse over myButton then set textbox value as 3. Then binding this value to ViewModel property, at this time, the new value of ViewModel property also be 3.
The textbox just like a bridge. Can I remove this bridge and change the VM property directly when <setter..... in myTrigger style? thanks.
<Style x:Key="myTrigger" TargetType="TextBox">
<Style.Triggers>
<DataTrigger Binding="{Binding IsMouseOver, ElementName=myButton}" Value="True">
<Setter Property="Text" Value="3"></Setter>
</DataTrigger>
</Style.Triggers>
</Style>This definitely works:
<Button Height="50" Width="100">
<Button.Triggers>
<EventTrigger RoutedEvent="Button.MouseEnter">
<BeginStoryboard>
<Storyboard
Storyboard.Target="{Binding}"
Storyboard.TargetProperty="MyNum">
<DoubleAnimation To="3.0" />
</Storyboard>
</BeginStoryboard>
</EventTrigger>
</Button.Triggers>
</Button>
Viewmodel:
public class MainWindowViewModel : DependencyObject
public double MyNum
get { return (double)GetValue(MyNumProperty); }
set
SetValue(MyNumProperty, value);
// Using a DependencyProperty as the backing store for MyNum. This enables animation, styling, binding, etc...
public static readonly DependencyProperty MyNumProperty =
DependencyProperty.Register("MyNum", typeof(double), typeof(MainWindowViewModel), new PropertyMetadata(callBack));
static void callBack(DependencyObject d, DependencyPropertyChangedEventArgs e)
Console.WriteLine(e.NewValue.ToString());
Hope that helps.

Error Binding DatePicker control Date property
I am building a Universal App and am getting a run time error on my DatePicker control when trying to bind the Date property.
I have this in my XAML:
<DatePicker x:Uid="StartDate" Header="Start Date" Date="{Binding StartDateUtc, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}"/>
I am binding it to a DateTime property called StartDateUtc. However when firing up the app, I am getting this error:
Exception = {"The text associated with this error code could not be found.\r\n\r\nFailed to assign to property '%0'. [Line: 42 Position: 63]"}
Position 63 happens to be the Date Property. If I remove it, the control is displayed.Hi Craig,
>> I'm not sure a whole project is needed. Here's the XAML
I failed to reproduce your issue “Failed to assign to property”. Could you please share a sample project through OneDrive to help us reproduce this issue?
By the way, the type of
DatePicker.Date property is DateTimeOffset rather than DateTime. Please try the ViewModel as following and let me know if it makes any difference.
public class CustomViewModel : INotifyPropertyChanged
public event PropertyChangedEventHandler PropertyChanged;
private void NotifyPropertyChanged([CallerMemberName] String propertyName = "")
if (PropertyChanged != null)
PropertyChanged(this, new PropertyChangedEventArgs(propertyName));
private DateTimeOffset _startDateUtc;
[RestorableState]
public DateTimeOffset StartDateUtc
get
return this._startDateUtc;
set
if (value != this._startDateUtc)
this._startDateUtc = value;
NotifyPropertyChanged();

H:selectOneMenu value binding to managed bean property
Please help. Cannot figure out why selectOneMenu value binding is not working...
The main contents of my jsp:
<h:form id="form1" rendered="true">
<P>
<h:selectOneMenu value="#{MBListBoxExample.selectedProject}" rendered="true"
required="false">
<f:selectItems value="#{MBListBoxExample.items}" />
</h:selectOneMenu>
</P>
<h:commandButton value="ShowSelected" rendered="true" action="#{MBListBoxExample.showSelected}" />
</h:form>I have a managed bean with a property that is basically a custom object:
private Project selectedProject;The selectOneMenu gets populated with the following code in my managed bean:
public List getItems() {
try {
ArrayList projectList = new ArrayList ();
projectList.add(new Project(1, "Project 1"));
projectList.add(new Project(2, "Project 2"));
projectList.add(new Project(3, "Project 3"));
projectList.add(new Project(4, "Project 4"));
ArrayList itemList = new ArrayList();
for (int x=0; x<projectList.size(); x++) {
SelectItem tempItem = new SelectItem();
Project tempProj = (Project) projectList.get(x);
tempItem.setLabel(tempProj.getName());
tempItem.setValue(tempProj);
itemList.add(tempItem);
return itemList;
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
return null;
}The following code is tied to my command button to display some simple output when the button is clicked:
public void showSelected() {
System.out.println("The selected item is: " + selectedProject.getName());
}If I set the value of the SelectItem (tempItem) above to a String and make the selectedProject variable of type String, the code works.
My goal is to have the items in the list reference 'Project' objects and be able to get to the selected object when the user clicks the command button.
Any help is greatly appreciated.The problem is that you're missing a converter. JSF needs to convert your values from Strings into Projects and vica verca.
When you do the form submission the values are passed as strings along with the labels. JSF isn't smart enough to convert them automatically. -
Binding of super class property
can we bind super class property, for example:
class A
private String message;
pubic String getMessage()
return "My Message";
public void setMessage( String message )
this.message = message;
class B extends A
}now my managed bean returns me a collection of class B objects, and i want to bind in JSF page poperty of its super class like that:
<h:outputText value="#{b.message}" />
It gives me a error "PropertyNotFoundException: b.message.
Is it possible in JSF ??
regards,
Y_NOT_I threw a quick test up on my JSF app and it works fine for me. It is not because of polymorphism. It must be in the way you are accessing the method. A typo or something small. Or perhaps it's because you are using a collection (and not accessing the Collection properly)?

Hello,
Dev. Env. : JSP/Struts - Indexed Properties
<c:forEach var="lines" items="${MbrLines.map.lines}">
<td>
<html:select name="lines" indexed="true" property="loc" >

StringBuffer sb = new StringBuffer();
DBAccess dba = new DBAccess();
sb = dba.fillDropdown("ALLLOC",0,"");

This is the code I have in a JSP used for edits. I fill the dropdown with all available locations(e.g. Chicago, Miami etc) from a database table.
How do I set the current value in the record to be edited, say "Chicago", to be "selected" in the dropdown? Or, is there a way to pass the property�s current value to the DB method ?
Any help is greatly appreciated. Thanks in advance.the HTML generated as folllows:
as you may see, the bean has been interpreted to array, which I have correspondent set method in form. Please check the code for form in my previous post.
If I radio button of any row, it sets all the rows. which looks very strange to me, because it shows to me that the beans has been seperated by using different names. as poDisplayVO[0] ; poDisplayVO[1] ; poDisplayVO[2.
