JSF + Liferay: Cannot send parameters from a bean to another -


i've tried methods, nothing works, in destination @postconstruct parameter null.

i sending redirect beana page (backed beanb) , trying extract parameter beanb. requirement not add parameters url.

i tried methods:

  • facescontext.getcurrentinstance().getexternalcontext().getsessionmap().put("userid", userid);
  • @sessionscoped bean,
  • ec.getflash().put("userid", userid);

any suggestions? redirecting with:

 facescontext facescontext = facescontext.getcurrentinstance();         facescontext.getexternalcontext().redirect(url);

the portlet api knows 2 session scopes: portlet_scope , application_scope

the default bridge maps attributes in session map portlet_scope, means attributes visible portlet.

if want write , read session attributes portlets, have use: 

portletsession session = ((portletsession) facescontext.getcurrentinstance().     getexternalcontext().getsession(true));  // set session.setattribute(attributename, value, portletsession.application_scope); // object value = session.getattribute(attributename, portletsession.application_scope);

in xhtml can use #{httpsessionscope.attributename} well.
