[OpenLayers-Users] WPSExecute with a WFS reference using filter

[Alexandre Dubé]

Hi list,

   I found the answer in the tests for the WPSExecute format: 
https://github.com/openlayers/openlayers/blob/master/tests/Format/WPSExecute.html#L519. 
So "Yes", the WPSExecute does support wfs query references that with 
filters.

   Here's what I added to make it work, data being an instance of 
OpenLayers.Protocol.WFS.v1 :

         if (data.defaultFilter) {

           input.reference.body.wfs.filter = data.defaultFilter;

         }


   On the app side, here's how I use the WPSProcess object:

   wpsProcessBoundary.execute({

     inputs: {

       'InputPolygon': wfsProtocol

     },

     output: "Result",

     success: function(outputs) {

       console.log(outputs);

     }

   });


   So everything's working fine for me now.  Still, I'd be happy to hear 
about my approach, that being sending a wfs protocol as input data and 
using its inner defaultFilter property as the way to know if the 
protocol is using a filter or not.  Comments would be welcome.

Thanks,

Alexandre
