Description
In RHDM 7.4.x / 7.5.0, there is a limitation of 12 consequence bindings in the LHS of a rule when using the executable model. The following rule results in an error during the rule base compilation:
rule useSumOf when
$input : InputDataTypes( $no1Count_1 : no1Count
, $no2Count_1 : no2Count
, $no3Count_1 : no3Count
, $no4Count_1 : no4Count
, $no5Count_1 : no5Count
, $no6Count_1 : no6Count
, $no7Count_1 : no7Count
, $no8Count_1 : no8Count
, $no9Count_1 : no9Count
, $no10Count_1 : no10Count
, $no11Count_1 : no11Count
, $no12Count_1 : no12Count
, firings not contains \"fired\")
then
$input.setNo12Count(functions.sumOf(new Object[]{$no1Count_1, $no2Count_1, $no3Count_1, $no4Count_1, $no5Count_1, $no6Count_1, $no7Count_1, $no8Count_1, $no9Count_1, $no10Count_1, $no11Count_1, $no12Count_1}).intValue());
$input.getFirings().add("fired");
update($input);
end
In 7.5.1, this limitation is being changed to 13 bindings due to RHDM-1130 / DROOLS-4672.
For 7.6.0, the plan is to allow 24 bindings, see RHDM-1133.
These limitations should be listed in the documentation.
