timeout for Map#addLayers

Question

Hello All,

I'm looking for a way to set the timeout for the addLayers method on esri.Map, similar to the way in which one sets a timeout on esriRequest.

When I add a list of mapservices to a Map, and one of them is unresponsive, I have to wait for 60 seconds before the layers-add-result event fires.

Can someone please help?

Thanks!

Thanks for your reply Manish.  I don't think though that your suggestion will address my problem.  I'm already checking for the timeout on individual layer, e.g.
setLayerTimeouts: function() {
   //setup timeouts for each layer to load
   this.layerTimeouts = {};
   dojo.forEach(this.mapServices, function(svc) {
      this.layerTimeouts[svc.id] = setTimeout(dojo.partial(this.layerTimeoutHandler, svc), 5000);
   }, this);
},

layerTimeoutHandler: function(mapservice) {
   logger.warn("failed to load layer "+mapservice.id);
   mapservice.suspend();
},

My issue is that if I wish to take advantage of the DeferredList and not have to track the status of the collection myself, I'm subject to the 60 second timeout before the onLayersAddResult event fires.

Hi John,

You can try the below function change the values as required. you can use a conditional check such as while you add layer to map provide a Id to it. and check map.getLayer(Id). if this is not undefined then add another else you can set the timeout.

//Add the layers, after pausing briefly

setTimeout(function()
{     
    console.log("pausing a few seconds");     
    map.addLayers(mapLayers); 
},1000);

hope this helps.
