Hi,
I don't know if your "dialog.Login" class is derived from
"qx.ui.window.Window"...
But if it is, the code (see below) works fine for me

// Center this window on screen as proposed here:

loginWidget.addListenerOnce("resize", this.center, loginWidget);
I think you can remove the following block, then:
