Can't use $this->load->database() anywhere?

[eluser]Unknown[/eluser]
Hi,

I'm using CI 1.7 with codecrafter to generate the scaffolding. This makes me realize the i can't use $this->load->database() anywhere, only in the constructor, otherwise no connection is created.
What could be happening? am i doing something wrong?

I think that using $this->load->database() in any function should work because the codecrafter use it a lot.

any ideas?

thanks
