Hi Wolfgang,<br>Whats the advantage of option 2 over 1? Can you give sample code for option 2??<div><div></div><div><br><br><div class="gmail_quote">2010/10/13 Wolfgang Laun <span dir="ltr"><<a href="mailto:wolfgang.laun@gmail.com" target="_blank">wolfgang.laun@gmail.com</a>></span><br>

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.<br>

I'd say you are using <br> dialect "mvel"<br>There is no try/catch statement in MVEL. You have the options:<br><br>(1) Use Java, not MVEL.<br><br>(2) Surround the fireAllRules() with try/catch and put it in a loop that's terminated<br>
if there is no exception.<br><br>-W<br><br><br><div class="gmail_quote"><div>2010/10/13 sumatheja <span dir="ltr"><<a href="mailto:sumatheja@gmail.com" target="_blank">sumatheja@gmail.com</a>></span><br>

Hi All, <br><div><div></div><div> 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]"<br>
<br>Here follows my code<br><br><br clear="all"><b>rule 'Test rule'<br>ruleflow-group "Test Ruleflow"<br>no-loop<br> when<br> $c:Car()<br> Driver()<br> <br> then <br> try{<br>
$c.getModel()<br> } catch (Exception Ee) {<br> System.out.println("caught an exception: "+Ee.toString());<br> }<br>end</b><br><br>However if i remove the try catch block it buils fine.<br>
<br>Can anyone let me know if i'm missing something here.<br><br>Thanks in advance :)<br>-- <br>cheers<br><font color="#888888">Sumatheja <br><br><br>
