<div dir="ltr"><br> Yes it is. May I ask you please to open a JIRA? it is a really simple mistake, in case you want to fix it locally and provide a patch while we don't release a new version. It is a wrong cast here:<br>

<blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">Hi,<br>
<br>
<br>
I have the following drl file.<br>
<br>
<br>
==================================<br>
<br>
package bugTestingFail<br>
<br>
rule "Price hits Target"<br>
when<br>
eval ( true )<br>
then<br>
end<br>
<br>
==================================<br>
<br>
<br>
It is managed by a RuleAgent.<br>
<br>
<br>
However, when I change the drl file from the source, I get the following except<br>
ion:<br>
<br>
<br>
RuleAgent(MARKET_DATA) INFO (Wed Aug 06 15:43:53 EST 2008): Applying changes to<br>
the rulebase.<br>

at java.util.TimerThread.mainLoop(Timer.java:512)<br>
at java.util.TimerThread.run(Timer.java:462)<br>
<br>
This only happens to me when I am editing rules files that have an eval<br>
condition.<br>
<br>
Is this a bug?<br>
Cheers,<br>
Niall<br>
