Arvados » Arvados Workbench 2

Currently to get list of trashed files one has to add:

includeTrash: true

to /groups/{uuid}/contents call. The problem with that is all files that belongs to uuid will be returned even not trashed ones. That causes problems with trash panel where only trashed files should be displayed. Client has to manually filter out items that has isTrashed set to true. That works but doesn't integrate well with limit and offset parameters. Client can't rely on that when user switches page or changes items per row. So it would be good is filtering on server by isTrashed field was possible. Currently that is not working

Filters like this should work:

filters=[["uuid", "is_a", ["arvados#collection", "arvados#group"]], ["is_trashed", "=", true]]

Here is a test case:
