I am getting an error when I have something like the following:
rule "test eval"
when
cell1 : Cell(value1 : value != 0)
cell2 : Cell(value2 : value < value1)
eval(true)
then
System.out.println("setting value to " + (value2.intValue() + 1));
cell2.setValue(value2.intValue() + 1);
modify(cell2);
end
where Cell is
public class Cell {
int value = 0;
public Cell2(int value)
{
this.value = value;
}
public int getValue() {
return value;
}
public void setValue(int value) {
this.value = value;
}
}
The error is

When I remove the eval it works.
