Hi Will,

Can you send me the XML? Are you saying you cannot import the assessment
because of the NullPointerException?

Also, can you show me the result of following queries:

Get the item_id of this multiple choice question of the core assessment:
SELECT * FROM sam_item_t WHERE itemid = :item_id
SELECT * FROM sam_itemtext_t WHERE itemid = :item_id
SELECT * FROM sam_answer_t WHERE itemid = :item_id

Get the published_item_id of this multiple choice question of the published
assessment:
SELECT * FROM sam_publisheditem_t WHERE itemid = :published_item_id
SELECT * FROM sam_publisheditemtext_t WHERE itemid = :published_item_id
SELECT * FROM sam_publishedanswer_t WHERE itemid = :published_item_id

Please let me know if you have problem of above queries.

Thanks,
Karen
