[mapserver-dev] getExpressionString issue

[Donald]

I'm using MapServer version 6.2.0, in Ubuntu. I pasted a piece of the code
that I'm using that is a little different from the one you presented but
it's working for all expressions that don't have dots in it. Do you think
that it could be a problem related to MapServer version ?


   public static function _zoomtoclass ( $_map, $_classname ){

        $class = $_map->getClassByName($_classname);
        $layer = $class->getLayer();

        if ($class->isPostgisType()){
            $connection = $class->getConnection();

            $metadatatable = $class->getMetadataDataTable();
            if ($metadatatable != ''){
                $table = $metadatatable;
            } else {
                $table = $class->getDataTable();
            }

            $postis_table_obj = new ngPostgisLayer($connection, $table);

            $classitem = $class->getClassitem();

            $expression = $class->getExpressionString();
