Comments on Column Macro (Velocity)

how can i include link into this macro? the result i get is the xwiki syntax, i.e. ~~[[[http://code.xwiki.org/xwiki/bin/view/Macros/ColumnMacro]]~~]~~

This macro seems to not work properly at version 2.1.25683. First: the way to create and use macros in this version has changed. Second: When I call the first column macro, the renderer seems to create a </div> automatically and does not wait for the endcolumn to create it.
