Application layout

[eluser]emperius[/eluser]
I just read the wiki article http://codeigniter.com/wiki/layout_library/

and tried to do this at my application but I get a error
Fatal error: Call to a member function on a non-object in /home/worldofm/public_html/apartments/system/application/controllers/chisinau.php on line 12

When I tried to find out what's the problem I saw that load object doesn't exist in the controller

chisinau Object
(
[_ci_ob_level] =>
[_ci_view_path] =>
[_ci_is_php5] =>
[_ci_is_instance] =>
[_ci_cached_vars] => Array
(
)

[_ci_classes] => Array
(
)

[_ci_models] => Array
(
)

[_ci_helpers] => Array
(
)

[_ci_plugins] => Array
(
)

[_ci_scripts] => Array
(
)

[_ci_varmap] => Array
(
[unit_test] => unit
[user_agent] => agent
)

[_ci_scaffolding] =>
[_ci_scaff_table] =>
)

What is the problem?
