What's the correct syntax for adding multiple operationalLayers?

IB1 — Sat, 02 Mar 2013 22:17:41 GMT

I'm working off of a template and am trying to add multiple operationalLayers. I feel like I've tried every possible combination.

If I just add one layer, it works fine:

operationalLayers: [{
  type: "feature",
  url: "http://xxxxxx.com/arcgis/rest/services/xxx/xxx/FeatureServer/5",
  options: {
   id: "Fiber1",
   title: "Cable",
   opacity: 1.0,
   visible: true,
   infoTemplate: new esri.InfoTemplate(),
   mode: esri.layers.FeatureLayer.MODE_SNAPSHOT
  }
 }],

But when I try to add another, none of them load when I start the index.html:

operationalLayers: [{
  type: "feature",
  url: "http://xxxxxx.com/arcgis/rest/services/xxx/xxx/FeatureServer/5",
  options: {
   id: "Fiber1",
   title: "Cable",
   opacity: 1.0,
   visible: true,
   infoTemplate: new esri.InfoTemplate(),
   mode: esri.layers.FeatureLayer.MODE_SNAPSHOT
  }
  type: "feature",
  url: "http://xxxxxx.com/arcgis/rest/services/xxx/xxx/FeatureServer/4",
  options: {
   id: "Fiber2",
   title: "Junction",
   opacity: 1.0,
   visible: true,
   infoTemplate: new esri.InfoTemplate(),
   mode: esri.layers.FeatureLayer.MODE_SNAPSHOT
  }
 }],

What am I doing wrong here?

Thanks for any help.

Asked too soon! I figured it out. My brackets probably aren't how they are suppose to be location wise, but oh well.

operationalLayers: [
  {type: "feature",
  url: "http://xxxxxx.com/arcgis/rest/services/xxx/xxx/FeatureServer/5",
  options: {
   id: "Fiber1",
   title: "Cable",
   opacity: 1.0,
   visible: true,
   infoTemplate: new esri.InfoTemplate(),
   mode: esri.layers.FeatureLayer.MODE_SNAPSHOT
  }},
  {type: "feature",
  url: "http://xxxxxx.com/arcgis/rest/services/xxx/xxx/FeatureServer/4",
  options: {
   id: "Fiber2",
   title: "Junctions",
   opacity: 1.0,
   visible: true,
   infoTemplate: new esri.InfoTemplate(),
   mode: esri.layers.FeatureLayer.MODE_SNAPSHOT
  }}
],

It would indicate to you if your json was fomatted corretly. Basically it would have indicated to you that you had the parens incorrectly placed.
