[mart-dev] bug? Missing header info for exons

[Johanna Eddy]

If I use the MartView to obtain exon info along with the transcript sequence, 
the header is missing some of the sequence type and rank data. The query looks 
like this:

my $query = 
BioMart::Query->new('registry'=>$registry,'virtualSchemaName'=>'default');


        $query->setDataset("hsapiens_gene_ensembl");
        $query->addFilter("with_refseq_dna", ["Only"]);
        $query->addFilter("chromosome_name", ["Y"]);
        $query->addAttribute("str_chrom_name");
        $query->addAttribute("gene_stable_id");
        $query->addAttribute("transcript_stable_id");
        $query->addAttribute("transcript_chrom_start");
        $query->addAttribute("transcript_chrom_end");
        $query->addAttribute("exon_stable_id_v");
        $query->addAttribute("type");
        $query->addAttribute("exon_chrom_start");
        $query->addAttribute("exon_chrom_end");
        $query->addAttribute("exon_chrom_strand");
        $query->addAttribute("rank");
        $query->addAttribute("transcript_exon_intron");

And some of the results look like this:

This one has 6 exon IDs, 6 exon start, 6 exon end, and 6 exon ranks, but only 3 
types.

This one has 18 exon IDs, 18 exon start, 18 exon end, but only 4 exon type, and 
15 exon ranks

Is this a bug, and can it be fixed?

Thank you,
