dojo/promise/all not working with esri/request

This seems pretty straightforward, but I'm unable to get it to work.

I'd like to get the layer infos for selected layers in my map service using multiple esri/requests with a promise. I have a visibleLayers array that I'm using to create each request:

<code>

var visibleLayers = [0,1];

var requestGroup = [];

array.forEach(visibleLayers, function(visibleLayer,i)

{

var requestHandle = esriRequest(

{

url: dynamicLayer.url+"/"+visibleLayer,

content: {f: "json"},

callbackParamName: "callback"

});

requestGroup.push(requestHandle);

});

promises = all(requestGroup);

promises.then(processResults);

function processResults(results)

{

//process results

}

</code>

Everything looks ok, but I never enter my processResults function. I know that the return for esriRequest is deferred, so I'm not sure what's going wrong.

Any ideas?

Thanks,

Jason
