Hi Kiran,
Attribtues from multiple AttributePages are not allowed to be queried
together. However, you can move (create a pointer) to the attribute that
you need from the offending page and leave them with other das
attributes within the same page.
Hope this helps,
Syed

I am getting the error: "Attributes from multiple attribute pages are
not allowed" when trying to use the built-in DAS server of BioMart 0.7.
My local mart is configured similar to Ensembl mart and so the filters
and attributes for the importable/exportable pairs ensembl_das_chr and
ensembl_das_gene are identical to Ensembl.
das_gene request works:
myserver/biomart/das/default__hsapiens_gene_ensembl__ensembl_das_gene/features?segment=....
but das_chr request
(myserver/biomart/das/default__hsapiens_gene_ensembl__ensembl_das_chr/features?segment=....)
doesn't work, and shows this error:
"Attributes from multiple attribute pages are not allowed"
The attributes listed in the ensembl_das_chr exportable are:
ensembl_gene_id,start_position,end_position,strand,ensembl_transcript_id,transcript_start,transcript_end,ensembl_exon_id,exon_chrom_start,exon_chrom_end
which does include attributes from multiple pages. If the I remove the
attributes from the structure page, I don't get an error.
I did see the post
(http://www.mail-archive.com/mart-dev@ebi.ac.uk/msg02381.html) saying
this feature (supporting exportable with attributes from multiple pages)
is not supported in BioMart 0.7.
How did Ensembl get around this? See :

Thanks,
