[rules-users] Inserting new Object

[Tina Vießmann]

Hi Edson,

I can't provide a test case. But I've figured out what the exception are 
about. It's not about the code I've posted before. It's about the 
exceptions that the java.util.Set.add() method throws. I've attached the 
concerned code at the end.
That means for me I have to manage the exception handling. I've tried to 
google the topic. The best I came up with is a mailing list entry: 
http://drools-java-rules-engine.46999.n3.nabble.com/Exception-handling-policy-td113782.html  
Would that be the correct solution? If yes, how do I implement the 
handler? I would be thankful for a code example.

The code that the exception references is:

    declare Watcher
         @role ( event )

         triggeringValue : Value
         numberOfContainedValues : int
         valueSet : Set  // Set<Value>
    end

    // ....

    function Watcher generateWatcherEvent(Value firstValue) {
         Watcher watcher = new Watcher();
         watcher.setNumberOfContainedValues(1);
         watcher.setTriggeringValue(firstValue);

         // add value to set
         Set set = watcher.getValueSet();
         set.add(firstValue);
         watcher.setValueSet(set);

         return watcher;
    }


Thanks for your help! :)

Tina
