Hey,
that totally sounds like a bug to me. Usually, the binding has a fallback which
checks the property definition for the event name and should use this. I did a
quick test in the playground and it seems to work in a basic setup:
qx.Class.define("A", {
extend : qx.core.Object,
properties : {
a : {
init: "xyz",
event: "affe"
}
}
});
var label = new qx.ui.basic.Label("test");
this.getRoot().add(label);
var a = new A();
a.bind("a", label, "value");
a.setA("XYZ");
Could you perhaps change the code to fail? Thats something that should work
just out of the box so we should figure out how to reproduce it and open up a
bug for that.
Regards,
Martin
