In order to display a topic using the new parser you need to ensure that flexwiki.config does _NOT_ have
<DisableNewParser>true</DisableNewParser>
which causes all access to the new parser to be shut off.
Then in the topic you have to add a property DisplayUsingNewParser with a value of 'true' as in this topic. You can verify that the new parser is being used as the division between sections of the borders is now a visible rule rather than just empty space when using the original parser
It is also necessary to modify the borders so that each border is wrapped in a div. If you are using the _ NormalBorders from FlexWiki then you can just copy the current borders fro this site. You will see that each border has a
Presentations.ContainerStart.("div", "Wrapper")
and a
Presentations.ContainerEnd("div")
at the start and end of each definition (though there are additional minor changes needed to make things work )
