Ditto call ignoring Filter

Hi, I’m using the following Ditto call for a blog system, with a Filter set in order to stop child containers from being outputted along with recent blog posts:

[!Ditto? &parents=`10` &depth=`0` &filter=`id,12,13,14,15,16` &sortBy=`createdon` &showPublishedOnly=`1` &tpl=`ditto.archivesummary`!]

So in theory it should stop containers with IDs 12 to 16 being shown. Unfortunately it isn’t working... can’t see why? Anyone have any ideas?

&filter=`id,12,2|id,13,2|id,14,2|id,15,2|id,16,2`

Thanks- seems to work well. I guess the "2" is interpreted as exclude... would a "1" be include?

No, it means the opposite - "exclude any document whose id field DOES NOT EQUAL 12 or 13 etc".
