Start parameter and result grouping

Hi,

I'm trying to implement paging when grouping is on.

Start parameter works, but the result contains all the documents that were
before him.

http://localhost:8983/solr/select?q=test&group=true&group.field=marketplaceId&group.limit=1&rows=1&start=0(I
get 1 document).
http://localhost:8983/solr/select?q=test&group=true&group.field=marketplaceId&group.limit=1&rows=1&start=1(I
get 2 documents).
...
http://localhost:8983/solr/select?q=test&group=true&group.field=marketplaceId&group.limit=1&rows=1&start=N(I
get N documents).

But in all these queries, I should get only one document in results. Am I
right?

I'm using this build: https://hudson.apache.org/hudson/job/Solr-trunk/1297/

Thanks.

Ah, seems you're just one day behind. SOLR-2207, paging with field collapsing, 
has just been resolved:
