Assuming Event has a field called "context" (which is set by the constructor you use in your RHS):-

when

 $p: RuleContext($size: getOldContext().getParent().getUsableSpace() > (30*1024*1024))   

 not Event( context == $p.getOldContext().getParent());

then

   Event event = new Event("folder almost full", $p.getOldContext().getParent(), new Date());

   event.display();

end

hi,

i have the following rule file :

rule "size"

when

 $p: RuleContext($size: getOldContext().getParent().getUsableSpace() > (30*1024*1024))  

then

   Event event = new Event("folder almost full", $p.getOldContext().getParent(), new Date());

   event.display();

end

im loading this rule file and executing the rules once in 10 seconds in a continuous loop from my java class. assuming the when part is always true, the event object created gets displayed each and every time once in 10 seconds. i want to create the object only once with the fact that the event is already there.. i.e.  i dont want to create the object again if it is already created.. how can i do that?

Thanks.
