converterfalsefalsejavax.el.ValueExpression
(must evaluate to javax.faces.convert.Converter)
Converter instance registered with this component. As a convenience this attribute is also allowed to evaluate to a java.lang.String, which will be used in a call to Application.createConverter(String converterId) to create the converter instance.
converterMessagefalsefalsejavax.el.ValueExpression
(must evaluate to java.lang.String)
A ValueExpression enabled attribute that, if present, will be used as the text of the converter message, replacing any message that comes from the converter.
idfalsetruejava.lang.StringThe component identifier for this component. This value must be unique within the closest parent component that is a naming container.
immediatefalsefalsejavax.el.ValueExpression
(must evaluate to boolean)
Flag indicating that this component's value must be converted and validated immediately (that is, during Apply Request Values phase), rather than waiting until Process Validations phase.
renderedfalsefalsejavax.el.ValueExpression
(must evaluate to boolean)
Flag indicating whether or not this component should be rendered (during Render Response Phase), or processed on any subsequent form submit. The default value for this property is true.
requiredfalsefalsejavax.el.ValueExpression

Flag indicating that the user is required to provide a submitted value for this input component.
requiredMessagefalsefalsejavax.el.ValueExpression
(must evaluate to java.lang.String)
A ValueExpression enabled attribute that, if present, will be used as the text of the validation message for the "required" facility, if the "required" facility is used.
validatorfalsefalsejavax.el.MethodExpression
(signature must match void validate(javax.faces.context.FacesContext, javax.faces.component.UIComponent, java.lang.Object))
MethodExpression representing a validator method that will be called during Process Validations to perform correctness checks on the value of this component. The expression must evaluate to a public method that takes FacesContext, UIComponent, and Object parameters, with a return type of void. As a convenience this attribute is also allowed to evaluate to a java.lang.String, which will be used in a call to Application.createValidator(String validatorId to create the validator instance.
validatorMessagefalsefalsejavax.el.ValueExpression
(must evaluate to java.lang.String)

The expression must evaluate to a public method that takes a ValueChangeEvent parameter, with a return type of void, or to a public method that takes no arguments with a return type of void. In the latter case, the method has no way of easily knowing what the new value is, but this can be useful in cases where a notification is needed that "this value changed".
