Thanks for the details.
The global doSomething(); I have used because I had no idea how to pass
the 'this' pointer.
Using the global doSomething(); is a similar approach as you describe
(I store the 'this' in a global
variable and use it later in doSomething();.
Is it possible to pass some hash code of 'this' to
doSomething(hashValue); (or to your static method)
and find the 'this' later by using this hashValue; Is there a lookup
built into qooxdoo to
search for a 'this' by having its 'hashValue' or similar?
Thanks
