tMemorizeRows - ArrayIndexOutOfBoundsException

Hello, I'm getting an ArrayIndexOutOfBoundsException error. I think I know why but wondering what the work around is.

So I have a dataset where a datetime column is being used in tMemorizeRows (column startTime). Since tMemorizeRows gets the previous value, I think I'm getting the error because of the first row, yes? Since the first row has no previous value.

When I get the value of startTime_tMemorizeRows_1[0] (position zero), it works fine because it's referencing the same row, but I get the error when reference position 1, startTime_tMemorizeRows_1[1].

Again, is it because of the first row? In my tJavaRow component, I tried to use an if conditional before assigning output value. But I still get the same error.

if (startTime_tMemorizeRows_1[1] != null)

what is the value of the Row count to memorize field? By default, it is 1, if you want to meorize multiple rows, you should increase this value.
