RPAS javaexpression and incremental mode of calculation.

Hi everybody!

I have a simple  RPAS javaexpression, that calculates A=B+C. I use it in calc rule group of the workbook. It takes B and C values with PopulatedIterator. There is a problem with calculation in incremental mode. If B or C are changed manually - everything is OK. But if B or C are changed by other rules in Calc rule group, populated iterator does not go through these changed cells, it takes nothing. What is the problem with my java?

Here is a block from my expression:

double[][] B = new double[iProdCount][iLocCount];

double[][] C = new double[iProdCount][iLocCount];
