I have a bit of a problem with WPS(1.0) chaining on GeoServer (2.9.1.).
I am following this tutorial for
http://geoserver.geo-solutions.it/edu/en/wps/chaining_processes.html
Chain 1: Extract the rivers into the “restricted areas” polygons
Problem is in third step, when i am choosing SUBPROCES of gs:CollectGeometries, imput XML looks empty
<?xml version="1.0" encoding="UTF-8"?><wps:Execute version="1.0.0"service="WPS" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://www.opengis.net/wps/1.0.0" xmlns:wfs="http://www.opengis.net/wfs" xmlns:wps="http://www.opengis.net/wps/1.0.0" xmlns:ows="http://www.opengis.net/ows/1.1" xmlns:gml="http://www.opengis.net/gml" xmlns:ogc="http://www.opengis.net/ogc" xmlns:wcs="http://www.opengis.net/wcs/1.1.1" xmlns:xlink="http://www.w3.org/1999/xlink" xsi:schemaLocation="http://www.opengis.net/wps/1.0.0 http://schemas.opengis.net/wps/1.0.0/wpsAll.xsd">
<ows:Identifier/>
<wps:DataInputs/>
<wps:ResponseForm/>
</wps:Execute>
It have no imput at all, and execute of the process will end up with ErrorMessage
"Failed to parse process inputs"
It happends not only with this example, but with all the chaining
This is a whole XML from process imputs/outputs
