Using
drools 5.1
mvel 2-2.0.14
In consequence (then) block : (dialect strict or not does not make a difference)
Trying to sum up some numbers after a multiplication operation. For example :
t.out = t.in2*t.in3 + t.in3*t.in4 + t.in2*t.in4;
(the object t has all its attributes of the type String), and all the t.in
parameters are actually numbers-as-strings.
So the multiplication is going on fine, as expected, but the addition (+) sign,
is concatenating instead of adding.
So the for inputs "1", "2" and "3", the result looks something
like : 2.06.03.0 (i.e concetenated) instead of the expected 11.0.
What is going worng How does the + operator decide to do concat instead of
doing addition.
Any documentation on this + operator logic ?
Note : The above works fine when I use MVEL without Drools.
Thanks
