Just a follow up on this one.

I just updated to DNN Article 6.01.03 and the problem persists.

Whenever I use Metapost to post an article the artcile contents end up in the description field instead of the content field.

I'm really sorry about the delay regarding this issue.  I see that the first entry was made on 2/7.  Arghh!  I didn't see this come through and I apologize for not seeing it until now.

Regarding the behavior of the ZLDNN metaPost provider, this was the behavior designed by ZLDNN for this module.  If there is only an entry (no use of the more tag which I'll describe in a second), then that entry is treated as the description.  If this entry is moved to the main content region, then nothing shows up as a description for the entry.

If you want the content to be saved in the content field, you can accomplish this is WLW by adding a split post marker (the More tag available from Format | Split Post) as follows:

In most cases, though, you’ll want to include both a description and a content region.

Again, I apologize for the delay and hope this answers your question. 

Thanks for using metaPost!
