AW: [rules-users] How to avoid circular rule activation fornoncircular problems?
Sorry for the line breaks. Here I post my changes in a (hopefully) more readable format:
rule "Calc StartTime with predecessors"
when
$t : Task(predecessorCount > 0, $predecessors : predecessors )
forall( $succTask : Task( this == $t )
$predTask : Task( this memberOf $predecessors, endTime > 0 ) )
$endTime : Number() from accumulate ( $p : Task() from $predecessors,
max($p.getEndTime()) )
# new constraint
Task( this == $t, eval($t.getStartTime() != $endTime.longValue()) )
then
$t.setStartTime( $endTime.longValue() );
System.out.println( "Drools: " + $t.toString() + " has new
StartTime" );
# new update
update( $t );
end
Best regards
Ralph
