In many cases, what shows in the preview pane is not actually an accurate preview of what the code will display. It shows correctly if I click to preview the page, but it doesn't display correctly in the preview pane of the editor.
And in some cases, it shows correct formatting in the preview pane, but when I actually click to view the page, it shows formatting codes rather than actual formatting.


@Suzanne Goldlust: The main reason for this difference is due to the way we currently implemented the solution. We use different rendering engines (one on the client side, when you are editing) and one on the server (for user facing website). We had to do this due to technology differences (Javascript on client and C# on the server).
We are going to address this issue by having the same engine on both client and server (Javascript). This task is now prioritized.
@Saravana Kumar: Terrific, thanks.
We have switched a single parser for markdown parsing. The same parsing engine will be made use of inside portal and inside the Knowledge base website. You will start noticing the differences for all the newly published articles and in preview.
