Errors with ocular v0.25 - undefined property: CI_Loader::$CI

[eluser]Gaz[/eluser]
HI all,

I'm getting an error when calling

Code:

ocular::yield()

from my view file. The error is

Code:

ERROR - 2008-10-31 12:55:01 --> Severity: Notice  --> Undefined property: CI_Loader::$CI /Users/Gaz/Sites/cisitebuilder/application/libraries/Ocular.php 182
ERROR - 2008-10-31 12:55:01 --> Severity: Notice  --> Trying to get property of non-object /Users/Gaz/Sites/cisitebuilder/application/libraries/Ocular.php 182

I'm sure this is something simple (Ocular is loaded via autoload.php), but I thought someone else might have seen this error before.

I'm using CodeIgniter version 1.7, by the way.

Cheers,
Gaz.
