Add possibiliti to generate stateless links Page and External links.
--------------------------------------------------------------------
Key: TAPESTRY-1895
URL: https://issues.apache.org/jira/browse/TAPESTRY-1895
Project: Tapestry
Issue Type: Improvement
Components: Core Components
Affects Versions: 4.1.3
Reporter: Alexander Gavrilov
Fix For: 4.1.4
For now External and Page service always generated statefull links.
In my application i generate links to send to the users, and those links
includes all "client" persistent state of pages, and encodes session ID. This
state ans session ID is not required for users when they access page first
time.
Whe can add parameter statfull to the ExternalServiceParameter class, and add
new class PageServiceParameter with page name and statefull attributes. In
PageService we can check what the type of passed parameter, and if it is
PageService, use it if not use the default behaviour. The defined "statefull"
parameter whe can bypass to the _linkFactory.constructLink method.
for ExternalService:
ExternalServiceParameter esp = (ExternalServiceParameter) parameter;
Map parameters = new HashMap();
parameters.put(ServiceConstants.PAGE, esp.getPageName());
parameters.put(ServiceConstants.PARAMETER, esp.getServiceParameters());
return _linkFactory.constructLink(this, post, parameters,
esp.isStatefull());
for PageService:
Map parameters = new HashMap();
final PageServiceParameter psp = parameter instanceof PageServiceParameter
? (PageServiceParameter)parameter : null;
parameters.put(ServiceConstants.PAGE, psp != null ? psp.getPage() :
parameter);
return _linkFactory.constructLink(this, post, parameters, psp != null ?
psp.isStatefull() : true);
