Version: (using KDE KDE 3.5.3) Installed from: Compiled From Sources Compiler: g++ (GCC) 4.1.1 20060525 (Red Hat 4.1.1-1) OS: Linux The member names are being displayed on the association lines! For instance if you have: class A private: B memberClass; When you place both class A and B in your diagram, class A shows the attribute "memberClass", but ALSO on the drawn composition line is the text "-memberClass". If you delete it, the text returns the next time you open the program.
Still valid in current trunk.
Could not reproduce in git master. If the issue persists feel free to reopen the bug.
