[rules-users] Please help

[Edson Tirelli]

   I may be misinterpreting your message bellow, but the way I read it,
being sarcastic instead of explaining what is your problem will not make
people help you.

   I think you need to read the manual, Rule language chapter. To raise only
one exception in case there is on or more matches, use the "exists" CE:

 when
    exists( LineItem( $parent: parentId ) and LineItem( id != $parent ) )
then
    // raise the exception
end
