I'd say you are using
   dialect "mvel"
There is no try/catch statement in MVEL. You have the options:

(1) Use Java, not MVEL.

(2) Surround the fireAllRules() with try/catch and put it in a loop that's terminated
if there is no exception.

Hi All,
        I have a set of rules. After firing the rules if an exception occurs in a rule the following rules are not getting evaluated. So i tried writing a try catch block inside the consequence part of the rule, but then i get an error saying "'unable to build the consequence.[Error:was expecting type: java.lang.Object but found type:null]"

Here follows my code


rule 'Test rule'
ruleflow-group "Test Ruleflow"
no-loop
    when
        $c:Car()
        Driver()
       
    then
       try{
          $c.getModel()
          } catch (Exception Ee) {
           System.out.println("caught an exception: "+Ee.toString());
          }
end

However if i remove the try catch block it buils fine.

Can anyone let me know if i'm missing something here.

Thanks in advance :)
