layer problems with recent geoserver and virtual service

[ischneider]

For some background: https://groups.google.com/a/opengeo.org/group/dev-mapstory/browse_thread/thread/e52db1a125e080e1?hl=en#

The problem is that recent geoserver builds do not include the workspace name in the virtual WMS getcapabilities response. This results in a layer not appearing in the viewer. At the time of this writing, this is not reproduceable on the dev server. A recent geoserver trunk build is needed. Removing the workspace name on the server side 'fixes' this issue.

The main reason is that we do a findExact in gxp's WMSSource plugin:

var index = this.store.findExact("name", config.name);

Maybe we could detect if a URL is virtual service, and then also match without the prefix? But if feels kind of hacky.

We can easily fix this at the GeoExplorer level, I think that makes more sense and is less hacky.

However it's kind of hard to make it work for both the old as well as the new situation, let me know when it makes sense to make the switch.

This would be the change in GeoExplorer.js:

diff --git a/src/geonode-client/app/static/script/app/GeoExplorer.js b/src/geonode-client/app/static/script/app/GeoExplorer.js

This would also require a Django change in the data page where the sources and layers are created for the viewer, it would need to do something similar as is done in javascript above.

config = Ext.apply(config, {"sources": {"1": {"url": "http://localhost:8080/geoserver/geonode/DC/wms", "restUrl": "/gs/rest", "ptype": "gxp_wmscsource"}, "0": {"ptype": "gx_olsource"}, "local": {"url": "/geoserver/wms", "restUrl": "/gs/rest", "ptype": "gxp_wmscsource"}}, "about": {"abstract": "", "title": ""}, "localGeoServerBaseUrl": "http://localhost:8080/geoserver/", "map": {"layers": [{"opacity": 1, "group": "background", "args": ["No background"], "visibility": false, "source": "0", "fixed": true, "type": "OpenLayers.Layer"}, {"opacity": 1, "group": "background", "args": ["OpenStreetMap"], "visibility": true, "source": "0", "fixed": true, "type": "OpenLayers.Layer.OSM"}, {"opacity": 1, "group": "background", "args": ["bluemarble", "http://maps.opengeo.org/geowebcache/service/wms", {"layers": ["bluemarble"], "tiled": true, "tilesOrigin": [-20037508.34, -20037508.34], "format": "image/png"}, {"buffer": 0}], "visibility": false, "source": "0", "fixed": true, "type": "OpenLayers.Layer.WMS"}, {"opacity": 1, "group": "background", "args": ["Wayne", "http://maps.opengeo.org/geowebcache/service/wms", {"layers": ["Wayne"], "tiled": true, "tilesOrigin": [-20037508.34, -20037508.34], "format": "image/png"}, {"buffer": 0}], "visibility": false, "source": "0", "fixed": true, "type": "OpenLayers.Layer.WMS"}, {"opacity": 1.0, "name": "geonode:DC", "selected": true, "visibility": true, "source": "1", "fixed": false}], "wrapDateLine": false, "projection": "EPSG:900913", "center": [null, null], "zoom": null, "units": "m", "maxResolution": 156543.03390625, "maxExtent": [-20037508.34, -20037508.34, 20037508.34, 20037508.34], "numZoomLevels": 22}, "defaultSourceType": "gxp_wmscsource", "apiKeys": {"google": "ABQIAAAAkofooZxTfcCv9Wi3zzGTVxTnme5EwnLVtEDGnh-lFVzRJhbdQhQgAhB1eT_2muZtc0dl-ZSWrtzmrw"}, "authorizedRoles": ["ROLE_ANONYMOUS"], "id": null});

I think this has all been addressed right @ischneider ?

Please reopen if I am wrong in closing this ticket.
