Re: [udig-devel] Selection filter changed
Ahh. The WFS layer. We are in the middle of trying to debug problems with wfs and advanced styling. It turns out that only simple styles will work right now. I'm not the one doing the work so I can't say more at the moment.
Cory should be able to say more when he pop's free from the rescue mission he is on right now.

Thanks Jesse. Unfortunately selecting it didn't make a difference. I assume that you mean selecting it in the Layers view? Manually re- rendering the map doesn't work either. 

I did find this in the console output every time I apply the filter:

Any idea where I can debug this? The layer is a WFS layer. Hang on a sec... that is actually a service exception being thrown from GeoServer as a result of this request:

There is no stack trace of where the error occurred.
Why is a request being sent back to GeoServer just to highlight a feature on the map? Has this always been the way? And if so, what changed? It's the same version of GeoServer (1.3.0) that we've been using for a while. 

Thanks,
Mark

Is they layer you are selecting on the selected layer? If it is not it may not be shown. This might also be a bug. Could you make sure that the layer is the selected layer and if it is not highlight then add a bug report. 

Does the highlight appear if you manually re-render the map?

Hi all,
Something else has changed since my last source update to revision 19235 (20/04/06). I used to use LayerImpl.setFilter() to highlight a feature on the map using a FID filter. Now this doesn't seem to work correctly. It just doesn't do anything at all and I can't seem to track down why.
Has anyone changed something to do with the selection stuff? Should I be doing this a new way? 

FYI, here is the code I am using to do this:

       IMap map = ApplicationGIS.getActiveMap();
LayerImpl eventLayer = (LayerImpl) getLayerByName (LAYER_ROADEVENT, map); //My own method 
              FilterFactory filterFactory = new FilterFactoryImpl();
       CompareFilter filter = null;
       try {
FeatureSource featureSource = (FeatureSource) eventLayer.getResource( 
                   FeatureSource.class, null);
filter = filterFactory.createCompareFilter (CompareFilter.COMPARE_EQUALS); FeatureType featureType = featureSource.getFeatures ().getSchema(); filter.addLeftValue (filterFactory.createAttributeExpression(featureType, "roadeventid")); filter.addRightValue (filterFactory.createLiteralExpression(id)); 
           eventLayer.setFilter(filter);
       } catch (Exception e) {
           e.printStackTrace();
       }



Thanks,
Mark
