Hi all:
I'm now tring to use ArcSDE 9.3 datasource, with ArcSDE sdk I can fetch a FeatureCollection by query, but when I call the FeatureCollection.features() method, an exception was threw: "PropertyDescriptor is null - did you request a property that does not exist?" at org.geotools.feature.type.ComplexTypeImpl.<init>(ComplexTypeImpl.java:71) at org.geotools.feature.type.FeatureTypeImpl.<init>(FeatureTypeImpl.java:50) at org.geotools.feature.simple.SimpleFeatureTypeImpl.<init>(SimpleFeatureTypeImpl.java:55) at org.geotools.feature.type.FeatureTypeFactoryImpl.createSimpleFeatureType(FeatureTypeFactoryImpl.java:154) at org.geotools.feature.simple.SimpleFeatureTypeBuilder.buildFeatureType(SimpleFeatureTypeBuilder.java:851) at org.geotools.data.DataUtilities.createSubType(DataUtilities.java:1306) at org.geotools.arcsde.data.ArcSDEQuery.getQuerySchema(ArcSDEQuery.java:274) at org.geotools.arcsde.data.ArcSDEQuery.createQuery(ArcSDEQuery.java:186) at org.geotools.arcsde.data.ArcSDEDataStore.getFeatureReader(ArcSDEDataStore.java:365) at org.geotools.arcsde.data.ArcSDEDataStore.getFeatureReader(ArcSDEDataStore.java:316) at org.geotools.arcsde.data.ArcSdeFeatureSource.getfeatureReader(ArcSdeFeatureSource.java:306) at org.geotools.arcsde.data.ArcSdeFeatureCollection.reader(ArcSdeFeatureCollection.java:111) at org.geotools.data.store.DataFeatureCollection.openIterator(DataFeatureCollection.java:229) at org.geotools.data.store.DataFeatureCollection.iterator(DataFeatureCollection.java:199) at org.geotools.data.store.DataFeatureCollection.features(DataFeatureCollection.java:188) ...... GeoTools is the 2.6 snapshot version. Anyone knows why or is working around it? Best regards, Wu ------------------------------------------------------------------------------ Come build with us!

Can you share a code snippet to reproduce?

Hi Gabriel：
I have found the problem, the geometry field which used in a filter is wrong. However, I think when the filter is wrong, featureSource.features(filter) should return null or throw an exception:) 2009/10/15 Gabriel Roldan <[hidden email]> Can you share a code snippet to reproduce? ------------------------------------------------------------------------------ Come build with us!
