Preview doesn’t work when using Custom Post

Hi,

I’ve been google-ing for days, hopefully someone out there can help me out with my problem.

I created custom post (ie “Column”) using the plugin Custom Post Type UI,
and changed the permalink for my custom post using Custom Post Type Permalinks.

Post Name: Custom
Permalink: http://DOMAIN/column/%post_id%.html

Everything works well,
– I can post my post correctly
– My post URL are correct

Except that, i can’t preview my post before publishing it.
When i tried to preview it, the preview URL shows :
http://DOMAIN/?post_type=column&p=102&preview=true
And it redirects me to my top page.

Once the post is published, the “Preview” button returns the following URL.
http://DOMAIN/column/102.html?preview=true

I’m assuming that something to do with the permalink, may i have any advise on how to fix the URL for preview ?

Thank you.
