Indeed there is a better solution for your issue. You don't have to
write an own "_applyText" method at all. For every property in qooxdoo
there are setter and getter methods automatically created. So you only
have to write
--snip--
construct : function(){
this.base(arguments);
this.initTextBox(new qx.ui.form.TextField());
this.add(this.getTextBox());
},
properties : {
textBox : {
deferredInit : true,
check: "qx.ui.form.TextField"
}
--snip--
to achieve your goal. So you can leave your custom "_applyText" method
behind. With the use of the "deferredInit" key the reference types are
not shared between the instances. However this feature is only available
with the latest copy of the 0.7.x branch or trunk version.

To get to know more about the power of properties just take a look at
the properties section in the online wiki documentation (
http://qooxdoo.org/documentation/0.7#properties )
