Hi Justin,
I ran now testEncodeFeatureCollection(), unfortunately I do get the same
error. Perhaps I still do something wrong with my POM file. I checked
manually the contents of the featureCollection and it contains
SimpleFeatures exclusively.
This is the error message:
3, 2008 11:39:11 AM org.geotools.xml.impl.GetPropertyExecutor visit
WARNING: [EMAIL PROTECTED]
(org.geotools.feature.DefaultFeatureCollection$1) is not of type
org.opengis.feature.simple.SimpleFeature
Any hint is highly appreciated.
Best regards
Theodor
