I develop with QtC all the time, but I never encountered this problem. Anyway, not a bug in UI toolkit, but qtcreator, and seemingly fixed in an upcoming release.

It always displays 'unimplemented command "evaluate"'. I wonder how the Ubuntu Touch developers manage to debug their code under such conditions. This bug is reported upstream <https://bugreports.qt- project.org/browse/QTBUG-37119> and reported to be "fixed by 6333e0913fc0078c0221a8909ced8df03a568992" in Qt 5.4. I suppose this is commit <https://qt.gitorious.org/qt/qtdeclarative/commit/6333e0913fc0078c0221a8909ced8df03a568992>. Could you please check if it is possible to backport this commit?
