Rolando,

You can get this date by getting the description property of a FeatureLayer:

FeatureLayer | API Reference | ArcGIS API for JavaScript 3.18 | Description

Or you can use esriRequest to get this as well.

Robert,
Can you explain me this example?
At this lines:
// InfoWindow expects an array of features from each deferred
// object that you pass. If the response from the task execution
// above is not an array of features, then you need to add a callback
// like the one above to post-process the response and return an
// array of features.
map.infoWindow.setFeatures([deferred]);

yes, it has comments but I don't understand.
Instead,
   var deferred = identifyTask
   .execute(identifyParams)
   .addCallback(function (response) {..} ,
I'm making,
   identifyTask.execute(identifyParams, function (response) {..} .

Instead .setFeatures([deferred]), I'm sending .setFeatures(feature), where feature = response[0].feature, and is saving the infoTemplate.

When I click the map, the infoWindow content is 'No information', Why?

Thanks a lot.

Thanks Rober, It was really helpful.

Rolando,

OK that is a very different question then. You would use the IdentifyTask for that.

thanks Robert,

But I want to know anything else:
Suppose that I click on map, right? So, the map is composed by little rectangs [0,1,2 ... sublayers or really, satellital images] at respective places. How can I get what layer (or rectangle of satellital image) I am clicking?

(sorry, if this question should not be here, I will republish it again)

Thanks a lot.
