getDefaultTemplate

protected String getDefaultTemplate()
Description copied from class: AbstractUITag
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 AbstractUITag
Returns:
The name of the template to be used as the default.

evaluateExtraParams

protected void evaluateExtraParams(com.opensymphony.xwork.util.OgnlValueStack stack)
First looks for the token in the PageContext using the supplied name (or TokenHelper.DEFAULT_TOKEN_NAME if no name is provided) so that the same token can be re-used for the scope of a request for the same name. If the token is not in the PageContext, a new Token is created and set into the Session and the PageContext with the name.

Overrides:
