Comparison check in CActiveFinder->Tablematch() method

I am running into a small problem when trying to get a simple relational AR query to work.  The error I am getting is:

'The relation "{relation}" in active record class "{class}" is specified with an invalid foreign key "{key}". The foreign key does not point to either joining table.'

I am curious if the following method should compare case-insensitive $table->name to $name?:

private function tableMatch($schema,$table,$name)

{


	if(strpos($name,'.')===false)   

                    return $table->name===$name;

	else


	{


		$table2=$schema->getTable($name);


		return $table->rawName===$table2->rawName;


	}


}       

In my case, it seems to be returning false based on comparing Tablename===tablename

(if this is not the issue, I will post more about the specifics of my tables, relations, etc…)

The comparison should be case-sensitive. Would you please show me the DBMS, table name and relation information?

Sure.  Here are the two related parent and child tables:

The Parent:

CREATE TABLE Post (

  id int(11) NOT NULL auto_increment,

  userId int(11) NOT NULL,

  title varchar(255) NOT NULL, 

  blurb text, 

  content text NOT NULL,

  createTime int(11) NOT NULL,

  updateTime int(11) NOT NULL,

  PRIMARY KEY  (id),

  FOREIGN KEY (userId) REFERENCES User(id)

  ON DELETE CASCADE

) ENGINE=INNODB;     

The Child:

CREATE TABLE Comment (

  id int(11) NOT NULL auto_increment,

  postId int(11),

  content text NOT NULL,   

  author varchar(150) NOT NULL,

  createTime int(11) NOT NULL,

  updateTime int(11) NOT NULL,

  PRIMARY KEY  (id),

  FOREIGN KEY (postId) REFERENCES Post(id)

  ON DELETE CASCADE

) ENGINE=INNODB;       

Post has one entry with id = 1, with two related comments in Comment. 

The relation defined in Post AR:

public function relations()

{


	return array(


		'comments'=>array(self::HAS_MANY, 'Comment', 'postId', 'order'=>'Comment.createTime DESC'),


	);


}   

And the query that generates the error:

$postList=Post::model()->with('comments')->findByPk(1);

Thanks.
