Method Details

getDefaultTemplate

protected String getDefaultTemplate()

Description copied from class: UIBean

A contract that requires each concrete UI Tag to specify which template should be used as a default. For example, the CheckboxTab might return "checkbox.vm" while the RadioTag might return "radio.vm". This value not begin with a '/' unless you intend to make the path absolute rather than relative to the current theme.

Specified by:

getDefaultTemplate in class UIBean

Returns:

The name of the template to be used as the default.

getControlType

protected HtmlControlType getControlType()

Description copied from class: UIBean

The kind of HTML control this component renders, used to decide which HTML5 constraint attributes are legal on it. Defaults to HtmlControlType.UNSUPPORTED, which supports no constraints — so a component that does not override this emits none.

Overrides:
