<![CDATA[Event Processing Filter Script not filtering]]>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!

We are getting into the system and it's really great, lots of rooms for scripts and customization!

Will be changed to false in next release.

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
