Finding org.jboss.seam.international.timezoneSelector

[lee3star.lee3star.gmail.com]

this is something I don't understand:

if I try to find it using API:

[lee3star.lee3star.gmail.com]

Contexts.getSessionContext().get(org.jboss.seam.international.timezoneSelector);

it returns null, even though I can find it from debug page:

[lee3star.lee3star.gmail.com]

debug console:

Session Context
...
org.jboss.seam.international.timeZoneSelector
...

however, if I use injection:

@In
private TimeZoneSelector timeZoneSelector;

the right value is injected.

why is that?
