The error is due to the getChildAt(0) in:
public int getIterationDepth(Map<String, Integer> inputDepths)
throws IterationTypeMismatchException {
// Check that all input depths are the same
int depth = getChildAt(0).getIterationDepth(inputDepths);
for (IterationStrategyNode childNode : getChildren()) {
if (childNode.getIterationDepth(inputDepths) != depth) {
throw new IterationTypeMismatchException(
"Mismatched input types for dot product node");
}
}
return depth;
}
It should, for safety, check that there is at least one child of the dot
product.
There's a larger problem in that a DotProduct somehow has no children.
I've added the two issues into Jira.
