_getResultsViewRecordFields does not need fields argument anymore. It now returns its own filter dictionary when called. Should be overwritten by subclasses who wish to use other filters.

 This module houses the GEOS exceptions, specifically, GEOSException and

    This exception is raised when an invalid index is encountered, and has
    the 'silent_variable_feature' attribute set to true.  This ensures that

    an Exception is raised.  Fixes ticket #4740.
