Steps to Reproduce

https://zkfiddle.org/sample/3b89sim/1-ForEachStatus
Check the result

Current Result

The last is always false.

Expected Result

Only the last row is true, otherwise false.

Debug Information

public boolean isLast() {
	return getIndex() == getEnd();
}

The expression is always false since the end value can't be reached. 18 != 20.
