public class Token
- extends UIBean
Stop double-submission of forms.
The token tag is used to help with the "double click" submission problem. It is needed if you are using the
TokenInterceptor or the TokenSessionInterceptor. The ww:token tag merely places a hidden element that contains
the unique token.
Examples
<ww:token />

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.
evaluateExtraParams
protected void evaluateExtraParams()
- 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:
evaluateExtraParams
in class UIBean
getTokenNameField
public String getTokenNameField()
- Deprecated. Templates should use $parameters from now on, not $tag.
- This will be removed in a future version of WebWork.
