Registering a Custom Validator on a Component

To register a custom validator on a component:

In the Visual Editor, select the component on which you wish to register a custom validator.
In the Component Palette, select the JSF Core page from the dropdown list, and then click Validator .
A dialog appears for you to enter the identifier (ID) of the custom validator as it is registered in the application.
Enter the validator ID and click OK.
This inserts the f:validator tag in the page.
(Optional) In the Component Palette, click Attribute in the JSF Core page.
A dialog appears for you to enter the name and value of the component attribute to set. Click Help if you need information about using the dialog.

Code sample

<h:inputText id="name" 
             value="#{MyBean.name}" 
             size="10" ... >
  <f:validator validatorId="customValidator" />
  <f:attribute name="someName" value"someValue" />
</h:inputText>
