Method Detail

createComponentEventLink

Link createComponentEventLink(Page page,
                              String nestedId,
                              String eventType,
                              boolean forForm,
                              Object... context)

Creates a stateful action link. Action links are built for components. Action links are encoded by the current request (that is, bound to the current request's session, if any).

Parameters:

page - the page holding the component

nestedId - the component's qualified id (a sequence of simple ids, separated by dots).

eventType - the type of event to trigger

forForm - true if the link is for a form, false otherwise

context - Additional path data, each value will be converted to a string and appended to the URI @return a link

ComponentResourcesCommon.createEventLink(String, Object...)

createPageRenderLink

Link createPageRenderLink(String pageName,
                          boolean override,
                          Object... pageActivationContext)

Creates a render link for the page. If an activation context is supplied then that context is built into the URI. If no activation context is supplied, then the activation context is obtained from the page itself, by triggering a passivate event on its root component. When the activationContext is an empty array, the targeted page is checked to see if it can provide an activation context. This is accomplished by triggering a "passivate" event on the targeted page. If the override parameter is true, this will not occur (even when the activation context is empty).

Parameters:

pageName - name of the page to which a link should be created

override - if true, then the provided activation context is always used even if empty

pageActivationContext - the activation context for the page

Returns:

a link

getLinkCreationHub

LinkCreationHub getLinkCreationHub()

Returns the hub, used to register and de-register LinkCreationListener2s.

Returns:

the hub
