DataMapper ORM v1.8.2

[eluser]WanWizard[/eluser]
Datamapper does:

Code:

static $CI = NULL;

// get the CI instance
is_null($CI) and $CI =& get_instance();

if( ! isset($CI->form_validation))
{
$CI->load->library('form_validation');
$this->lang->load('form_validation');
}
$this->form_validation =& $CI->form_validation;

Which is how you would do it in any library you would create. No rocket science. Do you also autoload the Datamapper library? Which version of CI? Which version of DM? Bootstrap properly installed?

Are you using some form of HMVC, which could interfere with CI's architecture of having a single instance?
