Currently when I open the select widget in web appbuilder the features currently set for selection match the layers I have check on in my layer list. I would like to modify the select widget code so that all the layers are unchecked by default and not tied to items checked on/off in the layer list.

Joel,

  If you are using WAB Dev edition then you can edit the select Widget.js in the _initLayers function (line 13):

_initLayers: function(layerInfoArray) {

      this.layerInfoArray = layerInfoArray;

      this.layerItems = [];

      this.selectionSymbols = {};

      html.empty(this.layerItemsNode);

      array.forEach(layerInfoArray, lang.hitch(this, function(layerInfo) {

        var visible = layerInfo.isShowInMap() && layerInfo.isInScale();

        var item = new SelectableLayerItem({

          layerInfo: layerInfo,

          checked: false,

          layerVisible: visible,

          folderUrl: this.folderUrl,

          allowExport: this.config ? this.config.allowExport : false,

          map: this.map,

          nls: this.nls

        });

Helen,

  Check the layerInfo to see if it is the layer that you need and if so don't change the SelectableLayerItem checked to false.

Hi Robert,

I just tried this line of code to see how it's like and already it gives me error : "Expected identifier or string".

Could you please tell me what is wrong with my codes ?  

Much appreciated!

_initLayers: function(layerInfoArray) {
this.layerInfoArray = layerInfoArray;
this.layerItems = [];
this.selectionSymbols = {};

html.empty(this.layerItemsNode);

array.forEach(layerInfoArray, lang.hitch(this, function(layerInfo) {
var visible = layerInfo.isShowInMap() && layerInfo.isInScale();

var item = new SelectableLayerItem({
layerInfo: layerInfo,


if (item.layerName ==='Accounts'){
checked: visible;
}
else {
checked: false;
}

layerVisible: visible,
folderUrl: this.folderUrl,
allowExport: this.config ? this.config.allowExport : false,
map: this.map,
nls: this.nls
});

Helen,


  You should not have an if statement inside a objects constructor like you do now. You need to do your if statement before the constructor for the layer selection object.

I have a WAB map. when the mapservice is not symbolized by a value the select widget shows the selection

when a map service is symbolized by a value the selection does not show. Is this a bug? The popup shows that I have a selection.
