Looks like the problem is that there are two agenda filter classes:<br>
org.drools.runtime.rule.AgendaFilter and org.drools.spi.AgendaFilter.<br>
<br>
odrr.AgendaFilter is what is required by the StatefulKnowledgeSession, this then wraps it in a class to convert it to an ods.AgendaFilter which is what the internal classes use.<br>
RuleNameEndsWithAgendaFilter seems to implement ods.AgendaFilter and not odrr.AgendaFilter which is what I'd expect - this is possibly a bug.<br>
Your options are to create a simple wrapper which converts an ods.AgendaFilter to an odrr AgendaFilter so that when you pass it into the knowledge session that can then wrap it back to an odsAF. Alternatively you could just copy or extend RuleNameEndsWithAgendaFilter and give it the 'correct' interface.<br>
