Views and passed variable scopes

The troubling part is the way it holds nested info.

What I find troubling is a situation where I might be repeatedly loading views and data loaded earlier sticks around:

PHP Code:

public function somemethod() {
        $foo = array(
            "val1" => "one",
            "val2" => "two",
            "val3" => "three"
        );
        $this->load->view("testview", $foo);
        
        $bar = array(
            "val1" => "changed one",
            "val2" => "changed two"
        );
        $this->load->view("testview", $bar);
    } 


When I load the view the second time with $bar--an entirely different data array-- then $val3 from $foo which was used the first time is defined. Here's a sample testview.php:

PHP Code:

<?php
/**
 * view to test scope when loading views in CI
 */
?>
<div>val1=<?php echo $val1; ?></div>
<div>val2=<?php echo $val2; ?></div>
<div>val3=<?php echo $val3; ?></div> 


And here's the output:

Code:

val1=one
val2=two
val3=three
val1=changed one
val2=changed two
val3=three

If I load a view and specify some entirely different data array, I would expect that only the keys in that array get expanded into vars within the view.
