<br> Looks like a bug to me. May I ask you plz to open a JIRA?<br><br> []s<br> Edson<br><br><div><span class="gmail_quote">2008/1/25, José Arrarte <<a href="mailto:jarrarte@gmail.com">jarrarte@gmail.com</a>>:</span><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">
Hello,<br><br>First of all, I'd like to thank all the people involved in making this tool such a great one (this includes whoever writes the reference manual as well).<br><br>I've been having some problems when comparing BigDecimals (using the compareTo method). I didn't find this issue in any previous post or in Drools' JIRA. However, I've been using Drools for a short time, so I hope you people can help me.
<br><br>The problem:<br><br>Firing this (simple) rule:
<br>
<br><span style="font-family: courier new,monospace;">
rule "Test Rule"
</span><br style="font-family: courier new,monospace;"><span style="font-family: courier new,monospace;"> when
</span><br style="font-family: courier new,monospace;"><span style="font-family: courier new,monospace;"> $dec : java.math.BigDecimal() from java.math.BigDecimal.TEN;
</span><br style="font-family: courier new,monospace;"><span style="font-family: courier new,monospace;"> eval( $dec.compareTo(java.math.BigDecimal.ONE) > 0 )
</span><br style="font-family: courier new,monospace;"><span style="font-family: courier new,monospace;"> then
</span><br style="font-family: courier new,monospace;"><span style="font-family: courier new,monospace;"> System.out.println("OK!");
</span><br style="font-family: courier new,monospace;"><span style="font-family: courier new,monospace;">end
</span><br style="font-family: courier new,monospace;">
<br>Fires this exception:
<br>
<br><span style="font-family: courier new,monospace;">
