Reflow Manager reflows ViewPools not obtained

[rampr]

I enabled debug in ReflowManager and tried the following code:

import ui.View as View;
import ui.ViewPool as ViewPool;

var Complex = Class(View, function(supr) {
  this.wrapper = new View({
    layout: "box",
    width: 350
  });
});

exports = Class(GC.Application, function () {

  this.initUI = function () {
    this.pool = new ViewPool({
      ctor: Complex,
      initCount: 1
    });
  };

  this.launchUI = function () {
  };
});
