Events
Type | Phases | Description |
---|---|---|
javax.faces.event.ValueChangeEvent | Process Validations, Apply Request Values |
The valueChange event is delivered when the value attribute is changed. |
org.apache.myfaces.trinidad.event.AttributeChangeEvent | Invoke Application, Apply Request Values |
Event delivered to describe an attribute change. Attribute change events are not delivered for any programmatic change to a property. They are only delivered when a renderer changes a property without the application's specific request. An example of an attribute change event might include the width of a column that supported client-side resizing. |
Attributes
Name | Type | Supports EL? | Description |
---|---|---|---|
attributeChangeListener | javax.el.MethodExpression | Only EL | a method reference to an attribute change listener. Attribute change events are not delivered for any programmatic change to a property. They are only delivered when a renderer changes a property without the application's specific request. An example of an attribute change events might include the width of a column that supported client-side resizing. |
binding | org.apache.myfaces.trinidad.component.core.input.CoreInputHidden | Only EL | an EL reference that will store the component instance on a bean. This can be used to give programmatic access to a component from a backing bean, or to move creation of the component to a backing bean. |
converter | javax.faces.convert.Converter | Yes | a converter object |
id | String | No |
the identifier for the component. Every component may be named by a component identifier that must conform to the following rules:
|
immediate | boolean | Yes |
Default Value: false whether the value is converted and validated immediately in the Apply Request Values phase, or is handled in the Process Validators phase, the default. By default, values are converted and validated together in the Process Validators phase. However, if you need access to the value of a component during Apply Request Values - for example, if you need to get the value from an actionListener on an immediate commandButton - then setting this to "immediate" makes that possible. |
rendered | boolean | Yes |
Default Value: true whether the component is rendered. When set to false, no output will be delivered for this component (the component will not in any way be rendered, and cannot be made visible on the client). If you want to change a component's rendered attribute from false to true using PPR, set the partialTrigger attribute of its parent component so the parent refreshes and in turn will render this component. |
required | boolean | Yes |
Default Value: false whether a non-null, non-empty value must be entered. If false, validators will not be executed when the value is null or empty. |
requiredMessageDetail | String | Yes |
the message to be displayed, if 'required' validation fails.
Parameters:
|
validator | javax.faces.el.MethodBinding | Only EL | a method reference to a validator method |
value | Object | Yes | the value of the component. If the EL binding for the "value" points to a bean property with a getter but no setter, and this is an editable component, the component will be rendered in read-only mode. |
valueChangeListener | javax.faces.el.MethodBinding | Only EL | a method reference to a value change listener |
