It's impossible to diagnose exactly what goes on without seeing the LHS patterns in detail. One possible reason for the rules rule[234] in groupX not firing the second time that group is given focus is that none of the objects participating in the LHS of the three rules has changed since the first time. Mixing condition evaluation by pattern matching with explicit control via a-groups and the like is tricky and apt to create surprises galore. Try to write the LHS so that they fully express the condition for firing; use groups only as a last resort. Hint: duplication of RHS code can be avoided by defining and calling functions. -W On Wed, Jun 24, 2009 at 4:42 AM, new2drools <rkbeach(a)gmail.com&gt; wrote: > > Hi All, > > Need some help with understanding setFocus. > > I have the following use case: > > if (condition1) { > > if (condition2) { > > } else if (condition3) { > > } else if (condition 4) { > > } > > } > > if (condition5) { > > if (condition2) { > > } else if (condition3) { > > } else if (condition 4) { > > } > > } > > I created 3 rules (rule2, rule3, rule4) for checking condition2, > condition3, > condition4 and > created 1 agenda group (groupX) for them. > > I created 2 rules (rule1, rule5) for checking condition1, condition5 and > created 1 agenda group(groupY) for them. > > rule "rule1" > agenda-group "groupY" > > when > // > then > drools.setFocus("groupX"); > end > > rule "rule3" > agenda-group "groupX" > activation-group "someActiveGroup" > > when > // > then > // > end > > >From the java code: > > ksession.getAgenda().getAgendaGroup("groupY").setFocus(); > > Problem: The first time, drools.setFocus("groupX") is invoked, I see that > it's working fine. rule2 or rule3 or rule4 get triggered.
