Cannot get MMM-Carousel 'positional' to work

[khrusher]

I am trying to use MMM-Carousel to swap out two modules located in the same location. Namely MMM-MyStandings and MMM-MyScorboard. I believe I have the configurations correct, however, they just display above each other.

In an attempt to debug and look for possible conflicts, I have created a very minimalist config. these two modules display at the same time. I added “showPageIndicators” to aid in debug, they do not display. it is if Carousel is not running

"modules":[
     {
        "module": "MMM-Carousel",
        "position":"bottom_bar",
        "showPageIndicators":true,
        "config": {
          "transitionInterval": 10000,
          "mode": "positional",
          "top_left": { "enabled": true }
        }
     },
   {
         module: "MMM-Pollen",
         position: "top_left",
         header: "Aiken Pollen",
         config: {
             updateInterval: 3 * 60 * 60 * 1000, // every 3 hours
             zip_code: "29801",
             show_icons: false
         }
     },
 {
        "module":"clock",
        "position":"top_left",
        "config":{
           "displaySeconds":false,
           "displayType":"analog",
           "analogSize":"180px",
           "analogFace":"face-003"
        }
     },
  ]

OK, I got this to work. there was an error in the console that I chased with some added console logging.

Positional does work as I had initially thought. I have two modules now swapping out in my bottom_left area.

The ignoreModules inside the position config is not optional.

@khrusher looking thru the code, I think the meaning of positional is ambiguous

this rotates BY POSITIONS… all modules in position top_left, then all modules in top_right
(if you defined BOTH those positions)

it does NOT rotate the modules inside A position…

I think positional is a shortcut to having to specify all the modules in the same position on a page…
