&nbsp;<br>&nbsp;&nbsp; 1.3.9 will work. You may try 1.3.12, but I didn&#39;t tested it myself.<br><br>&nbsp;&nbsp; []s<br>&nbsp;&nbsp; Edson<br><br><div class="gmail_quote">2009/2/3 Gras, Patrick <span dir="ltr">&lt;Patrick.Gras@generali.ch&gt;</span><br><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">

<p><font size="2" face="Arial">Hello,</font>
</p>

<p><font size="2" face="Arial">I just started to use Enums in my rules and I got following Exception during execution of the rule (compilation of rules is OK)</font></p>

<p><font size="2" face="Arial">[…]</font>

<br><font size="2" face="Arial">Caused by: org.mvel.PropertyAccessException: unable to resolve property: unable to resolve token: MetaType.cover</font>
</p>

<p><font size="2" face="Arial">MetaType is an Enum…</font>
</p>

<p><font size="2" face="Arial">I know my error may not be related with the version of mvel but I noticed I'm using mvel-1.3.1-java1.4.jar which looks like a version for java 1.4, so my question is what version of mvel should I use?</font></p>


<p><font size="2" face="Arial">I know I have to use a 1.3.* version, but I've read somewhere 1.3.13 won't initialise, so I guess I should use 1.3.12?</font>
</p>

<p><font size="2" face="Arial">Thanks for your help</font>
