$node->body is empty

Probably because I'm using WYSIWYG editor?
I'm not sure what's the correct fix.

print_r(array_keys((array)$node)); in spellcheck_nodeapi():
Array ( [0] => nid [1] => vid [2] => uid [3] => created [4] => type [5] => language [6] => changed [7] => title [8] => format [9] => revision [10] => log [11] => name [12] => date [13] => status [14] => promote [15] => sticky [16] => submit [17] => op [18] => preview [19] => delete [20] => preview_changes [21] => form_build_id [22] => form_token [23] => form_id [24] => teaser [25] => book [26] => menu [27] => path [28] => taxonomy [29] => links_related [30] => tagfields [31] => field_publication_date [32] => field_reference_number [33] => field_file_attachments [34] => field_tpip [35] => field_acknowledgements [36] => field_copyright_description [37] => field_copyright_notes [38] => field_copyright_expiry [39] => nodewords [40] => validated [41] => picture [42] => build_mode [43] => readmore [44] => content )

var_dump($node->body);
null

print_r($node->content);
