It would be nice to add posibility to configure path to extensions directory without redefining __create() method of application.
Problem is that in this case:
$app=Yii::createWebApplication($config);
Yii::setPathOfAlias('ext',$pathToExt);
$app->run();
Yii autoload can’t find classes.
Helps only using Yii::import(‘ext.path.ClassName’) necessary with ClassName, but it isn’t good.
Using other path alias for dir with extensions isn’t good because some extensions use path aliases with ‘ext.’
