dear list,
when i try to search a geoserver wms layer that is not queryable
(layer/publishing/wms settings Queryable unchecked), i've got an
error, which is misleading saying: "class java.util.HashMap produced
when FeatureCollection expected check schema use of
AbstractFeatureCollection".
the cause is:
at org.geotools.GML.decodeFeatureCollection(GML.java:451) the parsed
server response object is a HashMap, with contents:
{ServiceException={null=Layer Pilot:HouseNumbers_point_eov is not
queryable, locator=QUERY_LAYERS, code=OperationNotSupported},
version=1.1.1}
but the toFeatureCollection method is not able the handle the error
and throws an exception on line 484.
i am using geomajas 1.12.8 with gt-xml-2.7.4-GBE-276.jar, but the
relevant code in the trunk is the same. geoserver is 2.1.2,
(maven, win7, eclipse, gwt)
java.lang.ClassCastException: class java.util.HashMap produced when
FeatureCollection expected check schema use of
AbstractFeatureCollection
