Hello,
working on a project with qooxdoo I recognized, that the preconditions I
set in an interface were not evaluated correctly. It seems that my
classes do not implement their interfaces at all, although the code
looks fine and no error is thrown.
An example to illustrate the issue:
IMyInterface.js:
qx.Interface.define("itest.IMyInterface",
{
members:
{
testMe: function() { return false; }
}
});
MyClass.js
qx.Class.define("itest.MyClass",
{
extend: qx.core.Object,
implement: [itest.IMyInterface],
members:
{
testMe: function() { alert("You should not see this!"); }
}
});
Application.js (excerpt):
...
var test = new itest.MyClass();
alert("implements interface: "
+ qx.Class.implementsInterface(test, itest.IMyInterface)
+ ", has interface: "
+ qx.Class.hasInterface(test, itest.IMyInterface));
test.testMe();
...
The output is "implements interface: true, has interface: false" as if
the implement statement in the class definition is being ignored.
The testMe() method gets executed even though the precondition of the
interface evaluates to false.
A project of this simple example is avaiable here:

It would be very kind if someone could enlighten me.
Regards, eB.
