Thanks for the pointer. Deleted the whole paragraph because it has been
outdated in total.

I don't know when dispose has been removed or if it was only available in the
manual but its gone. But there is no difference for properties than for members
e.g. If you are the one creating the instance, you have to dispose it in the
destructor. Thats basically it. The dereference key only remove the internal
references which does not help much for qooxdoo objects which are always stored
in the object registry and need to be disposed.
