Get a continuation knowing its identifier, and set it as the current continuation
in the object model, in the same manner as cocoon.sendPageAndWait() does.
This action is useful when an Ajax request is made that needs to access data related
to the continuation that originally displayed the current page.
The continuation id is either the src attribute in <map:act>
or, if not specified, the continuation-id request parameter.
This action is successful if the continuation exists and is still valid.
act(Redirector redirector,
SourceResolver resolver,
Map objectModel,
String source,
Parameters parameters)
Controls the processing against some values of the
Dictionary objectModel and returns a
Map object with values used in subsequent
sitemap substitution patterns.

NOTE: This interface is designed so that implentations can be ThreadSafe.
When an action is ThreadSafe, only one instance serves all requests : this
reduces memory usage and avoids pooling.
objectModel - The Map with object of the
calling environment which can be used
to select values this controller may need
(ie Request, Response).
source - A source String to the Action
parameters - The Parameters for this invocation
Returns:
Map The returned Map object with
sitemap substitution values which can be used
in subsequent elements attributes like src=
using a xpath like expression: src="mydir/{myval}/foo"
If the return value is null the processing inside
the element of the sitemap will
be skipped.
