You see the Properties window for a Radio Button Group component
when you select the component on a page you are editing in the Visual Designer or in the Navigator window.
This component has the following properties.
Type: Stringid attribute. In the page bean, this property's value is the name of the RadioButtonGroup object.Type: int<table> element. The number of rows is defined by the length of the items array. The number of columns is defined by the columns attribute. The default layout is a single vertical column. Type: String for property is set to the first radio button in the group.
label property is not as flexible as the Label component. You can use the Label component if you want more control over the label's appearance, such as positioning of the label relative to the component. Type: int label property is set. Type: String position: absolute; left: 288px; top: 312px
You can enter values directly or click the ellipsis (...) button to use the Style Editor.

Type: Converterselected property. Type: Object com.sun.rave.web.ui.model.Option. Each Option instance represents one radio button. The value property of an Option instance represents the value of a selected radio button. If the items property is empty or the array, map or collection is empty, nothing is rendered.
For more information on com.sun.rave.web.ui.model.Option, include this class in the Java view of a page, put the cursor on the class name, and press Alt-F1 to see its Javadoc description.
By default, this property is associated with a com.sun.rave.web.ui.model.SingleSelectOptionsList object with a name similar to radioButtonGroup1DefaultOptions, whose node you can see in the Navigator window. This object serves simply to populate the group with default radio buttons. It is in the page bean.
Type: booleanfor property to this component, an error message will be displayed if the user tries to submit the page without selecting a radio button.
Type: Object At least one radio button should be selected by the application. The selected property must be set to a value binding expression that is evaluated to read and write an Object. When an Object value is read from the value binding expression, it identifies the selected radio button. The Object value must be equal to the value property of at least one Option instance specified in the array obtained from the value binding expression assigned to the items property.
The write method of the selected property's value binding expression is called during the UPDATE_MODEL_PHASE of the JavaServer Faces lifecyle. If a radio button is selected, an Object value is passed as an argument to the write() method. The Object value is the value of the selected radio button.
See the link to the Using Listbox Components tutorial at the end of the page for more information.
Type: MethodBinding(null), no validator is called. If you choose a validator, also select the required property to ensure that the validator is used.
Set the event properties by right-clicking the component in the Visual Designer and choosing Edit Event Handler > eventname.
validator property, right-click the component and choose Edit Event Handler > validate. The default name for the method is component-id_validate, where component-id is the value of the component's id property. When you define this method in this way, the validator and validate properties are automatically set for you. If you define a validator, also select the required property to ensure that the validator is used.
validator property. If you define your own validate method, do not separately change the value of the validator property, or you could lose the connection to your validate method.null. You typically define this method in the page bean by right-clicking the component in the Visual Designer and choosing Edit Event Handler > processValueChange. The default name for the method is component-id_processValueChange, where component-id is the value of the component's id property. Type: booleanreadOnly property concerning the effects of using the disabled property versus the effects of using the readOnly property. Type: booleandisabled property, JavaServer Faces does not detect that any value at all was submitted. Type: String title attribute for the component. The text value of this property displays if the user hovers the mouse cursor over the radio button group's label.
Type: booleanrendered property. Type: String Type: String Type: String Type: String Type: String Type: String Type: String Type: String Type: String Type: String Type: String Type: booleanThe most common example of an immediate action is a Cancel button. You make it immediate so that the normal validation and update steps can be skipped, but the action handler can still do whatever is necessary. Typically, the action handler will navigate back to some previous page. In some designs the action handler might also enqueue an informational message like "Transaction cancelled". It is possible to do more: for example, an application might record the fact that the user cancelled the current operation.
Type: booleanvisible property instead of this property.
You can bind this property to a JavaBeans property that determines when the component does get rendered. For example, an airline reservation form might show a component for frequent flyers and not show it for the general public. To bind this property, click the ellipsis button (...) to the right of the property and choose Use Binding in the dialog box.
Type: MethodBindingvalueChange property above, which provides an easier way to set this property's value. The valueChangeListener property is the MethodBinding that underlies the valueChange event property. The valueChangeListener property is updated when you set the method for the valueChange event property.
If you click the ellipsis button next to the valueChange property, you can use that property's property editor to choose an existing method to bind to, or you can create a new method or unbind an existing method. If you are an expert, instead of using the valueChange property, you can type a MethodBinding expression directly into this valueChangeListener property, for example, if you want to call a method that is not in the page bean.
