Rather than storing a new copy of a string, perhaps you could simply store the
disposition enum, and reflect a constant string back to JavaScript based on that
enum's value?

Spent a lot of time on this today:) Please check if the approach is in the right
direction.. Still cannot make IDL not to treat disposition as a string.. 

     String m_sourceFile;
     int m_lineNumber;
     int m_columnNumber;
