Question

Is it possible to exclude certain Facebook IDs in the apprequests dialog like the exclude_ids parameter in the old fb:multi-friend-selector?
I know about the filters property, but it seems not sufficient.

Answer 1

UPDATE:
Exclude Ids are now supported with Requests 2.0. You can pass a comma delimited list of UIDs with:

FB.ui({method: 'apprequests',
  message: 'Hello World',
  exclude_ids: '499802852,499804089'
  }, requestCallback);
