jpa - Dynamically loading data according to a session attribute -

i'm trying dynamically load dataset accordingly user session attribute, inject , set parameter in namedquery.

the namedquery works fine, i'm not getting dataset desired.

i mean, when session attribute 9882, dataset loaded corresponds findall query. but, in meantime, if user logs in app - , session attribute 4207 - dataset stills same 9882, means dataset still correspond findall query; , vice-versa: if 1st session attribute 4207, uses findbyprefdep query, expected, dataset still same 9882 session attribute logged after 4207 user.

@inject private string sessionprefdep; public collection<t> getitems() { if (items == null) { if (integer.valueof(sessionprefdep) == 4207) { items = this.ejbfacade.findbyprefdep(); } else if (integer.valueof(sessionprefdep) == 9882) { items = this.ejbfacade.findall(); } } homecoming items; }

does knows how can accomplish desired control?

thanks in advance.

----------- new section

the producer:

@applicationscoped public class beancdi { private final string sessionprefdep = (string) facescontext.getcurrentinstance().getexternalcontext().getsessionmap().get("xprefdep"); @produces public string sessionprefdep() { homecoming sessionprefdep; } }

the controller:

@inject private instance<string> sessionprefdep; public collection<t> getitems() { int sessionid = integer.valueof(sessionprefdep.get()); if ((items == null) && (sessionid == 4207)) { items = this.ejbfacade.findbyprefdep(); system.out.print("****************** findbyprefdep() - sessionid:" + sessionid); } else if ((items == null) && (sessionid == 9882)) { items = this.ejbfacade.findall(); system.out.print("****************** findall() - sessionid:" + sessionid); } homecoming items; }

you can via

@inject private instance<string> sessionprefded; //then in code int sesionid = integer.valueof(sessionprepdef.get());

this way should fresh value. depends how create object, far remember can inject strings in cdi producers.
