[rules-users] Do events have to be unique in terms of their field values?

Dear drools users, when using a rule to add events such as the rule below, I noticed that they are not inserted if the event has identical field values. When I change one of the values to another number they are inserted. Is this normal behavior? I assumed that the timestamp would determine them to be unique. rule "insertevents0" when then insert(new (TestFloatEvent(0)); insert(new (TestFloatEvent(0)); end I figured it might be that the timestamp is equal since they are inserted in the same rule. To be sure I waited and entered a second rule to be picked up by the scanner. rule "insertevents1" when then insert(new (TestFloatEvent(0)); insert(new (TestFloatEvent(0)); end Yet, the amount of events when I query the factbase is still 1 where I thought it would ahave been 4. Is the best way to fix this to add an explicit time attribute? The TestFloatEvents are declared as: package dynamictypesnetworktest declare TestFloatEvent @role(event) value : float @key end --- Dit e-mailbericht bevat geen virussen en malware omdat avast!
