Load select layers into templatePicker

williamcarr — Wed, 02 Apr 2014 14:24:02 GMT

Greetings,

I'm throwing together an app to add a series (107) feature layers for the attribute inspector. I also have a Editor/Template for adding point features. The problem is that the template picks up all the feature layers that are loaded.

var templateLayers = arrayUtils.map(evt.layers, function(result){
            return result.layer;

Is there a way to only display a couple feature layers for the template picker? I don't want to clutter the content pane and REALLY don't want anybody contaminating the other feature layers. I've checked samples and examples all day but, no joy.

Any ideas?

Sounds like you want to use filter instead of map?

http://dojotoolkit.org/reference-guide/1.9/dojo/_base/array.html#filter

I think your code would look something like this

var templateLayers = arrayUtils.filter(evt.layers, function(result){
                        return result.layer.id == "id of layer you want";
                    });

Found the answer after a couple more looks at it.

I pulled the

var templateLayers = arrayUtils.map(evt.layers, function(result){

return result.layer;

out completely. and changed

featureLayers: templateLayers,

featureLayers: [layer,layer2,layer3]

Tim's filter worked, but I was running too many layers(my best guess) and it was causing a timeout.

Cheers.
