A fix is submitted (​http://trac.osgeo.org/mapguide/changeset/r2678) to address the null pointer use. This fixes the issue of the unhandled exception which is bringing down the web server. A separate ticket is created (ticket #381) for the underlying issue of the incorrect handling for the ftsComposite feature type style.
