<br> Hi Barry,<br><br> I will look into that. Did you opened a JIRA? Which dialect are you using, java or mvel?<br><br> Edson<br><br><div class="gmail_quote">2010/4/7 Barry Kaplan <span dir="ltr"><<a href="mailto:groups1@memelet.com">groups1@memelet.com</a>></span><br>

** warning: This is a rant, but it just might save you some head scratching<br>
if you run into these issues **<br>
<br>
I really hate writing rules. Not, well not rules, but rules in the DRL<br>
language. There are so many edge conditions that fail silently. Here just<br>
two from today:<br>
<br>
...<br>
then<br>
retract(f1) // some comment<br>
retract(f2)<br>
end<br>
<br>
In the above retract(f2) will not be invoke. No message about any problems<br>
-- it just doesn't happen. Remove the comment and f2 is retracted.<br>
<br>
And, where 'ksession' is a global<br>
<br>
...<br>
then<br>
update(ksession.getFactHandle(f1), new MyF1(10, 10))<br>
end<br>
<br>
In this one the constructor used for MyF1 does not exists. No message, just<br>
silent failure. Change the rule to:<br>
<br>
...<br>
then<br>
MyF1 fi_new = MyF1(10, 10)<br>
update(ksession.getFactHandle(f1), f1_new)<br>
end<br>
<br>
And now the error message about the missing constructor is produced.<br>
