question

Hello, inside my Pager's onPageChanged I need access to the data/payload of the currently displayed element in order to decide whether to execute a certain command or not. Currently, this is not working, null is returned if I try:

...
"layouts": {
    "CustomPager": {
      "parameters": [
        {
          "name": "data",
          "default": []
        },
        {
          "name": "direction",
          "default": "vertical"
        }
      ],
      "item": {
        "width": "100%",
        "height": "100%",
        "type": "Frame",
        "items": {
          "type": "Pager",
          "data": "${data}",
          "width": "100%",
          "height": "100%",
          "navigation": "normal",
          "pageDirection": "${direction}",
          "id": "myPager",
          "onPageChanged":[
            {
              "type": "SpeakItem",
              "sequencer": "onPageChangedSpeaking",
              "componentId": "invisbleSpeechOuputText${event.source.value}"
            },
            {
               "type": "SendEvent",
               "delay": "${data.delay}",
               "arguments": [
                  "page:${data.number}"
               ]
            }
          ],
 ...

I do not simply need the current page index (I know that you can get it with event.source.value).

Do you know any solution to this problem or any workaround / suggestions to solve it?
