Commit 6cdc9859c38e55748bc20ac9fab7f4d2a3c14d9c

Fixing duplicate 'loading animation' getting added on  linked-data page.

     id: 'linked-data-container',
     initialize: function() {
       var self = this;
       this.loader_template = _.template($("#loader-template").html());
       $("#linked-data-page").prepend(this.loader_template());
       swtr.LDs = new LDSwts();
       swtr.LDs.getAll({
         what: 'img-anno',
         success: function(data) {
           swtr.LDs.add(data);
           if(!swtr.tagCloudView) {
             $("#spinner").remove();
             swtr.tagCloudView = new TagCloudView({collection: swtr.LDs});
+      if(!swtr.LDs) {
+        swtr.LDs = new LDSwts();
+      }
+      if(!swtr.LDs.length) {
+        console.log(swtr.LDs);
+        this.loader_template = _.template($("#loader-template").html());
+        $("#linked-data-page").prepend(this.loader_template());
+        swtr.LDs.getAll({
+          what: 'img-anno',
+          success: function(data) {
+            swtr.LDs.add(data);
+            if(!swtr.tagCloudView) {
+              $("#spinner").remove();
+              swtr.tagCloudView = new TagCloudView({collection: swtr.LDs});
+            }
           }
+        }
       });

     },
     destroy: function() {
