Geoffrey De Smet updated DROOLS-467:
------------------------------------
Description:
*The DRL in the first comment should throw a better error message than just IndexOutOfBoundsException. It should at least mention the line number.*
The rest of this discussion - which relates to decision tables etc - is irrelevant.
I apparently did something wrong in my xls. But the error message doesn't give me a clue.
