Hello,<br><br>First of all, I&#39;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&#39;ve been having some problems when comparing BigDecimals (using the compareTo method). I didn&#39;t find this issue in any previous post or in Drools&#39; JIRA. However, I&#39;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 &quot;Test Rule&quot;
</span><br style="font-family: courier new,monospace;"><span style="font-family: courier new,monospace;">&nbsp; when
</span><br style="font-family: courier new,monospace;"><span style="font-family: courier new,monospace;">&nbsp; &nbsp; &nbsp; $dec : java.math.BigDecimal() from java.math.BigDecimal.TEN;
</span><br style="font-family: courier new,monospace;"><span style="font-family: courier new,monospace;">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; eval( $dec.compareTo(java.math.BigDecimal.ONE) &gt; 0 )
</span><br style="font-family: courier new,monospace;"><span style="font-family: courier new,monospace;">&nbsp; then 
</span><br style="font-family: courier new,monospace;"><span style="font-family: courier new,monospace;">&nbsp; &nbsp; &nbsp; System.out.println(&quot;OK!&quot;);		
</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:
