Dear all,

Trying to reproduce the example in the biomaRt vignette using a mouse  
instead of
a human Affy array I sumbled on the following:

 > ids
[1] "1415670_at"   "1415671_at"   "1415672_at"   "1415673_at"    
"1415674_a_at"
[6] "1415675_at"   "1415676_a_at" "1415677_at"   "1415678_at"    
"1415679_at"
 > m.mart <- useMart("ensembl", dataset = "mmusculus_gene_ensembl")
Checking attributes and filters ... ok
 > genes <- getGene(id = ids, array = "affy_mouse430_2", mart = m.mart)
Error in getBM(attributes = c(attrib, "hgnc_symbol", "description",  
chrname,  :
	attribute: hgnc_symbol not found, please use the function  
'listAttributes' to get valid attribute names
 >

Any idea of what goes wrong?
Note that the vignette example does work on my system (not shown).
A query BioMart query (http://www.ensembl.org/Multi/martview) with
the same probes and array type did work as well .

I am using the following software versions
