Re: [rules-users] rule does not fire at first event

[ukriegel]

After insertion of the event, fireAllRules() is called.

In fact, there is in addition a default rule

rule "default"

dialect "java"
when Command() from entry-point "XXX"
then
System.out.println("No reaction on Command "+new Date());
end

which fires with the same timestamp as the rule which creates the fact
ActivityState

[Mauricio Salatino]

Are you calling the fireAllRules() method after inserting the events? or
using fireUntilHalt()?
You can activate the log to see what is happening with:
KnowledgeRuntimeLoggerFactory.newConsoleLogger(session);

[rules-users] rule does not fire at first event

[ukriegel]

Hi there,
we use drools fusion 5.3. Final.
In a drl-file, a fact and an event and the following rules are declared

package ... etc

declare ActivityState
@role(fact)
state : StateType
end


rule "set initial state"
dialect "java"
salience 100
when not (exists KFActivityState())
then
ActivityState $actState = new ActivityState();
$actState.setState(StateType.STANDBY);
insert($actState);  
System.out.println("ActivityState inserted "+ new Date());
end




declare Command
@role (event)
end


rule "request information"
dialect "java"
when Command(commandType == CommandType.REQUEST_INFORMATION) from
entry-point "XXX"
 $s: ActivityState(state == ComponentStateType.ACTIVE||state ==
ComponentStateType.PASSIVE||state == ComponentStateType.STANDBY)
then
 System.out.println("Send Report");
end


The rule request information doesn't fire with the first command event, but
from the second one it fires always.

What's wrong with my code?

Thanks in advance

Ulrich
