Get wpsResponse with application/json directly

[Gaetanbrl]

Hi,

We get a GeoJSON response from WPS as application/json to display on our OpenLayers map.

In this current version, we can only use row or document (textxml output format) but Openlayers can't correctly parsed the XML return by this type or response.

So, we need to allow application/json output format with wps-js lib because it works well with OpenLayers (tested).

For the test, we have change this code :

wps-js/src/web/lib/wps-js-all.js

Lines 1580 to 1583 in e56ffe3

	var ExecuteResponse_v1_xml = ExecuteResponse
	.extend({
	instantiate : function(wpsResponse) {
	if ($(wpsResponse).find("wps\\:ExecuteResponse, ExecuteResponse").length > 0) {

By adding on top something like that :

if (wpsResponse.type && wps.type == "featureCollection") { // get featureCollection json from wps response
	return wpsResponse
}

... and this work better.

Is it correct and how allow application/json format if not ?
