System information (as much as possible)

Additional comments

transitions is set before calling test for workflow_enabled:
See line 89ff in Featured/HtmlView for example:

	$this->transitions   = $this->get('Transitions');
	$this->vote          = PluginHelper::isEnabled('content', 'vote');

	if (ComponentHelper::getParams('com_content')->get('workflow_enabled'))
	{
		PluginHelper::importPlugin('workflow');

		$this->transitions = $this->get('Transitions');
	}
