The parser is not finished, so it cannot parse advanced templates as the ones in the STL.
There is an ongoing effort to improve the Code Completion (CC) in a separate svn branch,
but I don't think that that version is capable of parsing the std::map
There are two solutions:
1. you do checkout the cc_refactoring branch and start improving the parser;
2. wait until, someone does 1;
p.s. I'm not a CB developer, so I may be wrong about the things I say.
