Very very strange behaviour:
var log= qx.log.Logger.ROOT_LOGGER;
log.setMinLevel(qx.log.Logger.LEVEL_ALL);
qx.Class.include(qx.ui.basic.Atom,qx.io.databinding.MDataManager);
qx.Class.include(qx.ui.basic.Label,qx.io.databinding.MDataManager);
qx.Class.include(qx.ui.form.List,qx.io.databinding.MDataManager);
qx.Class.include(qx.ui.form.TextField,qx.io.databinding.MDataManager);
var at = new qx.ui.basic.Atom;
var la = new qx.ui.basic.Label;
var li = new qx.ui.form.List;
var tf = new qx.ui.form.TextField;
log.info ("qx.ui.basic.Atom.getDataBinding: " + at.getDataBinding);
log.info ("qx.ui.basic.Label.getDataBinding: " + la.getDataBinding);
log.info ("qx.ui.form.List.getDataBinding: " + li.getDataBinding);
log.info ("qx.ui.form.TextField.getDataBinding: " +
tf.getDataBinding);
INFO: root: qx.ui.basic.Atom.getDataBinding: undefined
INFO: root: qx.ui.basic.Label.getDataBinding: undefined
INFO: root: qx.ui.form.List.getDataBinding: function () { return
qx.core.Property.executeOptimizedGetter(this, clazz, name, "get"); }
INFO: root: qx.ui.form.TextField.getDataBinding: undefined
So the mixin seems to "stick" only to the qx.ui.form.List, but to none
of the other classes. Does anyone have an explanation?
