<b>What steps will reproduce the problem?</b>

Simply send an &lt;asks...&gt;&lt;roleFillers id=&quot;..:&quot;&gt;...&lt;/roleFillers&gt;&lt;/asks&gt; query.

<b>What is the expected output? What do you see instead?</b>

Unsupported 'ask' command response.

<b>What version of the product are you using? On what operating system?</b>

1.1.7 on linux.

Any chance this gets implemented any time in the near future? I guess there's some good (technical) reason for not supporting it (now). Just out of curiosity, what would that reason be?

This happens because in old days individuals were simulated by concepts in FaCT++, and the related commands were translated into concept axioms. So it was really hard to quickly answer queries like roleFillers and relatedIndividuals. Now individuals are singletons, but we forget to update code to support these features. Fixed now in trunc, would be available in 1.1.8.
