<div class="comment-block" style="background-color:#edf5ff;border:1px solid #dddddd;color:#000000;padding:12px;"><p>From that it seems that WARN is never appropriate. INFO might be.</p>
<p>The coding issue here is that the evaluation of the condition is done inside the plugin (in this case the specific attribute resolver). So by the time the engine notices that we got nothing back the decision was made.</p>
<p>In V2 it was considered bad enough to be a warning since I guess in that case it would be (for example) a SimpleAttribute Definition which returned no value because the data connector it was speaking to had not set up the attribute. In this case it was misconfiguration and so warn seems reasonable. In V3 we have this new reason for not returning the attribute which is perfectly accpetable and surely not a WARN or an INFO.</p>
<p>The options seem to include:</p>
<ul class="alternate" type="square">
<li>Move the test of the condition from the plugin to the Engine (or, perhaps just do it in both cases).</li>
<li>Make the warning debug and forget about it.</li>
<li>If we got no attribute back then decide about what level to log based on the presence of a condition on the plugin.</li>
<li>As above but actually run the (arbitrarily expensive) condition again.</li>
</ul>
<p>I think these all suck, but so does INFO/WARNing in this case.</p>
<p>I guess I favour the first.</p></div>
