EML2 Data Source problem with higgins.5087.3 - 'BaselineLayers'
To reproduce this bug, do a datasearch for 'BaselineLayers'. This shold give the
knb package 'higgins.5087.3'. The data for this package is a zip file stored on
the SRB; the data is treated as a single attribute table (i.e. not really a
table). When this datasource is dragged to the work area, a NullPointerException
is thrown 'at org.kepler.objectmanager.cache.DataCacheObject.getFileName'.
