Hi Wolfgang,
Whats the advantage of option 2 over 1? Can you give sample code for option 2??
In drl, you could use
dialect "java"
at outermost level, but one never does, because that's the default.
I'd use option (2).

Hi Wolfgang,
I am actually writing all the rules in a .drl and importing them into a guvnor. I didn't mention the dialect explicitly anywhere in the code. Is the default dialect MVEL. Is there a way to make one time declaration of dialect in my case instead of declaring it for all the rules.
2010/10/13 Wolfgang Laun <wolfgang.laun@gmail.com>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 :)
