Hi, people!

Problem resolved!

How I already had replaced the widget Beta 1 by Beta 2, I discovered that a array was being created wrong, including the indexs of groups. So I manipulated this array to remove all index of all groups before send to toggle the visibility.

This array is manipulated in ...\jimu.js\LayerInfos\LayerInfoForMapService.js, the method is "setSubLayerVisible". Follows the code of my solution:

   // Gets the correspondent layer info

   getLayerInfo: function(layerInfos, id) {

      var layerInfo = null;

      for (var i = 0; layerInfos.length; i++) {

        if (layerInfos.id == id) {

          layerInfo = layerInfos;

          break;

        }

      }

      return layerInfo;

    },

    // Removes all indexs of all groups

    clearVisibleLayers: function(visibleLayers, layerInfos) {

      var myVisibleLayers = lang.clone(visibleLayers);

      var myLayerInfos = layerInfos;

      var layerInfo = null;

      array.forEach(visibleLayers, lang.hitch(this, function(idVisibleLayer){

        layerInfo = this.getLayerInfo(myLayerInfos, idVisibleLayer)

        if (layerInfo && layerInfo.subLayerIds != null) {

          var index = array.indexOf(myVisibleLayers, idVisibleLayer);

          myVisibleLayers.splice(index, 1);

        }

      }), this);

      return myVisibleLayers;

    },

    setSubLayerVisible: function(subLayerId, visible) {

      var ary = [],

        index;

      if (subLayerId !== null) {

        // Here is the alteration

        ary = lang.clone(this.originOperLayer.layerObject.visibleLayers);

        ary = this.clearVisibleLayers(ary, this.originOperLayer.layerObject.layerInfos);

        index = array.indexOf(ary, subLayerId);

        if (visible) {         

          if (index < 0) {

            ary.push(subLayerId);

            this.originOperLayer.layerObject.setVisibleLayers(ary);

          }

        } else {         

          if (index >= 0) {

            ary.splice(index, 1);

          }

          if (ary.length === 0) {

            ary.push(-1);

          }

          this.originOperLayer.layerObject.setVisibleLayers(ary);

        }

      }

    },
