But what is funny for me - in rule "Check Object A and Set Default"<br>1) RHS = insertDefault(drools.getWorkingMemory()) - EXAMPLE IS NOT WORKING<br>2) RHS = drools.getWorkingMemory().insert(new SomeDefault()) - EXAMPLE IS WORKING CORRECTLY<br>

Agenda-groups segment the agenda and not the working memory :)<br>
Probably that is part of your confusion.<br>
