Hello,
I would love a pointer. Nodes in our system have a custom attribute "map" and I would like to filter event processing rules based on this value. What I have setup does not work. The filter passes all events, regardless of the custom attribute value. 
Does my filter look right? I would expect that if I've screwed it up, it would pass 0 events, but for some reason it passes everything.
Thanks a bunch!

				Okay I think I've solved my problem. Some nodes are missing the attribute.
if (GetCustomAttribute($node, "map") like "[RTH]*") {
    return true;
}
return false;
Into 
map_attr = GetCustomAttribute($node, "map");
if (map_attr != null && map_attr like "[RTH]*") {
    return true;
}
return false;
I assume 'null like "[RTH]*"' produces an exception. Though I would think an exception in the filter script would be equivalent to accept=false, but it seems exception means accept=true
			
			
			
				Yes, currently error is treated as true, which is not good. Will be changed to false in next release. 
			
			
			
				Great, thanks for all your hard work. We are getting into the system and it's really great, lots of rooms for scripts and customization!
