[rules-users] DSL debugging?

I have a very simple DSL snippet: PPositionQuantityAllocatedToLegs {position} {rulePriority}= Integer(intValue < {position}.quantity) from accumulate( StrategyLeg(priority > {rulePriority}, instrument == {position}.instrument, longShort == {position}.longShort, legQuantity : quantity) legsQuantity(legQuantity) ) In the IDE it seems to expand correctly without errors. However, at runtime I get the below error. How does one decipher such a message?
