Because the service model is threaded, this information is specific to a single request, and
will be discarded at the end of the request.public void store(java.lang.String pageName, java.lang.String idPath, java.lang.String propertyName, java.lang.Object newValue)

have to reflect changes made during the current request (this method is typically invoked as
part of rolling back a page to a prior state, before any further changes are possible).getStoredChanges

encoding
- Service encoding, which indentifies the URL and the query parameters from which
the ILink
will be created.post
- if true, then the link will be used for a post (not a get, i.e., for a HTML form);
