Hi

I'm trying to destroy an instance of the CKEditor with the destroy method but all I get is a JS-Error

"Message: 'theme' is null or not an object
Line: 22
Character: 1717
Code: 0"

URI: [blah]/ckeditor/ckeditor.js

my code is

window.onload = function() 
{

// CK Editor mit CKFinder 
CKEDITOR.replace( "t_text", { 
filebrowserImageBrowseUrl : "[removed unnecassary code]" 
});

CKEDITOR.instances['t_text'].destroy(); 
};

I also tried

CKEDITOR.instances.t_text.destroy();

same result
