How to put watch on non static map within class

[pdk5]

Hi,

In the following class

class CDiaConnection
{
public:
map<string, CDiaSession *> m_mSessions;
}

I am trying to add watch on the following map..How can i do this, as it is not global, it comes out of member functions, and it is lost..

somehow this map gets empty after some runs and i want to see where

thanks
