Hello Dietrich,
currently only the "init" value can be altered in "refined" properties.
Currently you have only two options:
1. Use the "changeValue" event. Everything you can do with an apply
method can also be done in the change event
2. Ask the original author (us) to add an apply method.
qooxdoo does have very few properties without either "apply" or "event"
so in must cases it is possible to catch the value change.
Best Fabian
