Hi Joel,
The whole point of globals is that you don't need to assert them you just
set them from the calling code, ie:
workingMemory.setGlobal("myList", arrayList);
You can then use myList in your consequence.
There is no way to use an asserted object in a consequence without binding
it to a variable in one of the conditions.
cheers
Steve
