Aliased Namespace Autocompletion

This bug has been marked as resolved multiple times, however it still appears in my Qt-creator 2.7.0.

For example, if I use
'namespace bfs = boost::filesystem;'
Qt-creator is not able to autocomplete any class, function or object name from this aliased namespace.
However, once I type e.g. 'bfs::exists(', the parameter hinting works.
