I get these errors when try to use my defined class.
1. The configuration key "deferredInit" of property "textBox" in class
"custom.TextBox" is not allowed!
2. this.initTextBox is not a function
So i'm totally clueless now, how to solve these problems. I can use the
class as i defined first, and it seems to me it works correctly, but still a
i wish to know how to use the initMyProperty() function. (I read the whole
qooxdoo manual
(http://qooxdoo.org/documentation/0.7<http://qooxdoo.org/documentation/0.7#properties>)
not just the property part)
