I'm trying to get some custom views for a content query rollup working in SharePoint 2010. I've made a custom News content type with a few basic columns like title, contents, comments and a custom column to toggle showing it on a certain page (boolean/checkbox).
I've edited my ItemStyle.xsl and added a new view type that has a title, image and description. In the settings of the web part (by default) the value of the description is taken from the 'comments' column. However, the description never shows up, just an empty div.
When I added the custom column to the description field (along with the comments column) the value of the custom column was shown. I'm 100% certain all the news items in my rollup do have a comment (it's even a required field). Yet somehow whatever I do the description does not show up.
How do I go about debugging this?
