  • I'm studying the tutorials and I have run into something unexpected.

    This is the code taken from Layout tutorial. I only changed the setLabel text (OneOne11111, TwoTwo22222:

    var Layout = require("Layout");
    var layout = new Layout({
      type: "v",
      c: [{
          type: "txt",
          font: "6x8:2",
          label: "A Test",
          id: "label"
          type: "btn",
          font: "6x8:2",
          label: "One",
          cb: l => setLabel("One11111")
          type: "btn",
          font: "6x8:2",
          label: "Two",
          cb: l => setLabel("Two22222")
    }, {
      btns: [{
        label: "Three",
        cb: l => setLabel("Three")
      lazy: true
    function setLabel(x) {
      layout.label.label = x;

    After the second click the label gets dirty (both on emulator and physical device). What's wrong?
