<div class="jive-rendered-content"><p>Hi,</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>I create prototype of business rule task for bpmn2 support. I tried to follow spec as much as possible (and as much as I understood it).</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>In general, it follows the same concept as RulesActivity and uses Drools for rules evaluation. So, you need to to provide facts for the business rule task that will be used to create state full knowledge session and fires all matching rules.</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>This is how definition of business rule task should look like (there can be many dataInputRefs)</p><pre class="jive-pre"><code class="jive-code jive-xml"><span class="jive-xml-tag"><businessRuleTask id="_3" name="Validation"></span>
