Left menu not generated when run site:site outside the pom.xm directory specifying the pom.xml location with -f maven argument

When a run the mvn site:site outside the root pom.xml 's directory, specifying the location of the pom.xml with the -f argument, the site menu is generated empty!

That is my dir structure:

My_CC_View\
       |
       |____My_CC_VOB\
                |
                |____project
                        |
                        |___pom.xml

So, I go to the My_CC_View and run the command:

mvn -f My_CC_VOB/project/pom.xml site:site site:deploy

The build goes ok, the site is generated, but without the left menu!!!!

This is because I'm using Continuum with ClearCase, and the directory structure is aways created like this on checkout, so I have to specify the pom.xml file with the relative path, and continuum runs the maven commands on the root view directory... and that is used as the basedir, not the pom.xml 's dir...
