Merging: Revision: [1644] Bad merge last commit had second param in the class_exists() call Revision: [1643] Fixed errors introduced in last changes: Variable that was passed the loadController function was not expected controller class name, It was the name fo the class without Controller. This would cause the loading to fail, since it was possible that a class was already loaded with the name that was passed. Example NewsController and a model called News. Revision: [1642] Added patch for MySql 5 Revision: [1641] removing second parameter in the class_exists function calls. closes Ticket #209 git-svn-id: https://svn.cakephp.org/repo/trunk/cake@1645 3807eeeb-6ff5-0310-8944-8be069107fe0
