It is a feature of the language, really. Changes to a variable containing a
number gives you a whole new number in that variable. What the variable
references actually changes. OTOH, changes to a member of a map or an array
does not change the map or the array that the variable is referencing.
Instead, it changes the contents of that map or array. If you were to assign
a new map or array to the variable, you'd get the desired effect. (That's
what you did when you moved the assignment into the constructor.) If you
just modify the map or array that was provided in the members: section, the
reference to the map or array is unchanged, so all instances are playing
with the same map or array.
There is qooxdoo documentation talking about this issue. I don't recall
exactly where, though.
Cheers,
